P e t r o l - L i n e X t r a

Petrol-Line Xtra and Petrol-Line Vent Xtra complement the existing Petrol-Line systems with a range of Polyamide lined ‘fuelproof’ medium density polyethylene pipe in sizes 50mm, 63mm,90mm and110mm. For ease of assembly and jointing sizes50mm and 63mm Petrol-Line Xtra are available as single wall or‘close fit’ secondary contained coils.

Manufactured utilising the latest co-extrusion technology, Petrol-Line Xtra has a sophisticated, wholly polymeric, structurethat gives superior performance. Technically advanced polymertechnology ensures liner to pipe integrity even at maximum extension.

The highly visible bonded polyamide liner demonstrates excellent resistance to petrol and alcohol fuel blends and allowsno measurable permeation of fuel through the pipe wall underindependent testing. The smooth surface of the barrier layer provides superior hydraulic flow characteristics.

Petrol-Line Xtra pipes are fully compatible with the existing range ofPetrol-Line electrofusion and transitionfittings and accessories.

The enhanced ductility of mediumdensity polyethylene allows tightbends to be formed more easilyduring installation and improvesthe ‘systems’ overall flexibility andease of handling.

Offset Fill, Vent and Vapour recovery

Designed to improve the service and operation of petrol filling stations, Petrol-Line Vent Xtra reduces filling time and increasesthe venting characteristics of underground storage tanks (UST).

Polyamide lining ensures immeasurable permeation, providing a

cost-effective and environmentally sensitive pipework solution to

service station installations.

Petrol-Line Vent Xtra has been independently tested and is

approved to the Institute of Petroleum

Performance Specification for Pipework at Petrol Filling Stations.

Superior mechanical and physical properties

Petrol-Line Vent Xtra has a wholly polymeric structure that

combines the strength and flexibility of medium density

polyethylene with the chemical resistance of polyamide.

Pipe is rated SDR17* to support improved flow characteristics

and available in sizes 63mm, 90mm and 110mm, jointed using

the full range of Petrol-Line electrofusion fittings.

Lined to resist absorption and permeation

With an identical polyamide liner to that employed in Petrol-Line

Xtra, the Vent Xtra system displays exceptional resistance to

absorption and permeation of petrol and alcohol fuel blends, and

outstanding dimensional stability.

When used in conjunction with Petrol-Line Xtra delivery lines, the

complete system has negligible system losses through permeation

of fuel in either its liquid or saturated vapour phase.

Improved flow characteristics

The smooth bore and low frictional resistance of Petrol-Line Vent

Xtra, and an approximate 20 per cent improvement in cross

section area, ensure faster site fuel deliveries and reduced risk of

back pressures being generated in the underground storage tank.

Vent Xtra Petrol-Line Xtra

Improved flow characteristics

* Standard Dimensional Ratio (SDR) The ratio between the wall thickness and outside pipe diameter remains constant. This relationship is called the standard dimensional ratio or SDR. It can be expressed as an equation:

SDR= nominal ( minimum ) outside diameter

minimum wall thickness

Secondary containment pipes arealso available in straight lengths for90mm and 110mm sizes.

Manufactured ‘in line’ the systemcombines the integrity of Petrol-Line Xtra with a robust,close fitting, polyethylene outersheathing. Self centering ribsadd to the system’s strength andmaintain the intertitial space.

Petrol-Line Xtra – Secondary Containment

To satisfy the environmental con-cerns with respect to emission ofVOCs and accidental fuel lossesparticularly in pipe systems convey-ing fuels under pressure, Petrol-Line Xtra in sizes 50mm and63mm can be supplied with closefitting secondary containment pipein 6m and 10m straight lengthsand 50m coils.

Sump connections are made usingflexible rubber boots and connectortubes.

System DescriptionThe Durapipe Petrol-Line system comprises a complete range of polyethylene pipes,electrofusion fittings (couplers, elbows and tees) together with electrofusion long spigotand extended, threaded and compact flange, transition fittings.

Petrol-Line Technology and Product DesignAll Petrol-Line pipes have been designed to provide optimum performance in Forecourt/Service Stationapplications. Petrol-Line Xtra and Petrol-Line Vent Xtra are manufactured to comply with the requirements ofthe IP Specification for Underground PipeworkSystems at Petroleum Filling Stations.

Electrofusion FittingsAll Petrol-Line electrofusion fittings employ thesame basic principles of operation. The sockets ofthe fittings incorporate an electrical heating coil. An Electrical Control Unit (ECU) supplies the controlled electrical energy necessary to heat the coilto form and expanding pool of polyethylene material.The continued induction of heat energy causes the jointinterfaces to melt under controlled pressure mixing the pipe meltand fitting melt, which is vital to produce good fusion. On completion of the heating cycle the pipe/fitting assembly is left to cool whilst the polyethylene material solidifies to form an homogenous union which is stronger than either the pipe or the fitting. This method of jointing produces high integrity, consistently reproducible electrofusion joints.

Hot and cold zones, sometimes called melt and freeze zones, areformed when energising the fitting coil. The length of these zonesis particularly important. The precisely controlled pitch and positioning of the coil in relation to the inner surface of the fittingnecessary to ensure uniform heat distribution is achieved by theuse of unique preform technology.

Each zone ensures that fusion is controlled to a precise length ofthe fitting socket and that the melt pressure is controlled throughout the entire jointing process.

Petrol-Line electrofusion fittings are manufactured with 39.5 voltconstant voltage operation for safe site installation.

E l e c t r o f u s i o n P r i n c i p l e s

• Heating coils are as close to the joint interfaces as possible.

• Wire position is accurately controlled during manufacture andthe subsequent fusion process.

• Heat distribution is uniform over the length of the hot zone.

• Melt pressure and temperature are both accurately controlled.

• Coils are protected from damage prior to, during and afterfusion.

• Pipe and spigot ends are peeled.

The design and unique manufacturing techniques of the Petrol-Line system ensures positive compliance with all these criteria.

Electrofusion Control UnitDurapipe manufactures electrofusion control units to meet all conceivable needs. In addition, a comprehensive range of accessories is also offered. Electrofusion control units are designedto operate from an electrical mains or field generator supply having an output of 110v and a rating of generally 3 to 3.5kVAfor 39.5v fittings and 6 to 7kVA for 80v fittings.

All ECUs manufactured after 1st Jan. 1996 for sale into Europecomply with the Electro-Magnetic Compatibility Directive and areCE marked.All units have been designed for arduous site conditions. They areequipped with combined carrying and protective frames.

Bar Coded Electrofusion FittingsTechnology is now available which eliminates the need to enterthe fusion time manually. Special control units can be suppliedwith the ability to read a bar code where fixed to an electrofusionfitting. These machines have a ‘light pen’ attached which theoperator uses to input the data contained within the bar code. Barcode control units also have data logging facilities to ensure traceability of welding parameters. An output socket allows thedownloading of this information onto a computer database orprinter to obtain a complete record of the joints which have beenmade. This information can be downloaded daily, or on completion of the project. The units will store up to 200 operations.

The ECU will display a description of the fitting which includesthree digits to denote size and this should be read and checkedby the operator before proceeding.

Temperature/Fusion time comparisonDuraFuse products are designed to work on a fixed fusion time fortemperatures between -5ºC and +23ºC. Where the time is beingentered manually then temperature compensation is not normallynecessary within these parameters. The bar code system willautomatically adjust the fusion time by small amounts to compensate for variations in ambient temperature can be obtainedfrom Durapipe Technical Support Department.

Durapipe recommend the Electrical Control units are serviced tocheck the calibration of the machine every 12 months to ensureoptimum performance.

The joint is achieved by eliminating all rubber sealing rings, gland nuts etc. normally associated with alternative mechanicalcompression fittings, and replacing with a simple copper crimp ring.

The crimp joint is made by pushing the pipe onto the spigot ofthe fitting (joiner or transition) and then crimping the copper ringon to the assembly using the hand operated crimping tool.

NB. The 32mm Petrol-Line Xtra pipe at each end of the coil maybe oval where it has been cut during the manufacturing process.To enable the Crimp fitting to be inserted in to the bore of thepipe it may be necessary to form an internal chamfer at the pipe end.

Jointing• Where required, cut the 32mm Petrol-Line Xtra pipe to the

required length. Ensure that the pipe is square.

• Form an internal chamfer inside the pipe to ease the insertionof the crimp fitting spigot.

• Slide the copper ring onto the pipe.

• Remove and discard the cardboard protection.

• Install the fitting in the required position – particularly relevantto transition fittings where the threaded joint should be com-pleted before the crimp is made.

• Push the 32mm Petrol-Line Xtra pipe on to the spigot of the fitting.

• Slide the crimp ring over the pipe so that it is in contact withthe acetal location washer. (Which should, itself, be in contactwith the central shoulder of the fitting.)

• Position the 32mm crimping tool centrally over the coppercrimping ring.

• Close the jaws of the tool lightly over the crimp ring and checkthat the tool is centrally located and completely covers thecopper ring.

• Screw the arms of the tool fully together until the tips of bothjaws touch. This completes the joint.

• Remove the crimping tool.

• Test the pipework to the appropriate standards.

Petrol-Line electrofusion fittings are designed to operate on a fixedfusion time for ambient temperatures between -5°C and +23°C.Jointing in extremes of ambient temperatures falling outside ofthis range will affect the amount of power (electrical energy)needed to produce a satisfactory weld and minor adjustments willneed to be made to the fusion time.

When installing Petrol-Line fittings using a Manual ElectrofusionControl Unit (ECU) the fusion time will have to be adjusted inline with the Temperature Compensation table detailed below.

Automatic Electrofusion Control Units are programmed to meas-ure the ambient temperature and will automatically adjust thefusion time. This information will be stored in the unit’s memoryand can be downloaded to create a permanent record of theinstallation parameter.

Prepared surfaces should always be clean and dry. Pipe preparationshould always take place immediately prior to fusion. If for any reason fusion is not possible, the prepared surfaces must be coveredto keep them clean, for example using a clean plastic bag.

If left for any considerable time the surfaces must be cleaned withan Isopropanol wipe (Code 53 451 100).

Pipe surfaces should always be prepared using the Petrol-Line Multipipe preparation kit developed to achieve positive grip in the pipebore. Interchangeable mandrels and sleeves ensure that a firm basefor the pipe peeling tool will be provided whether the pipe wall sections are Petrol-Line Xtra or Vent Xtra.

Cut the pipe square using the pipecutter. The use of a cutter ensures a square swarf-free pipe end preparation.

Pipe Surface Preparation -Petrol-Line XtraPrepare the pipe surface using thePetrol-Line Multi Surprep tool.

Mark the socket depth of the fittingon the outside of the pipe using amarker pen.

Select the correct size mandrel to fit the pipe being prepared.

Select the correct size sleeve for the pipe being prepared, where required.

Rotate the mandrel shaft anti-clockwise so that the mandrelsleeve is slightly expanded. Presentto the pipe bore and further rotatethe mandrel stem anti-clockwise sothat the assembly expands andfirmly grips the inside of the pipe.

Place the preparation toolonto the shaft and slidealong by depressing therelease button to disen-gage the drive until thecutter is aligned with themarked socket depth.Slacken the tool post tightener so that the cutter shoe is1mm above the pipe surface. Tighten the tool post tightener and rotate the knob onthe top of the tool post through 90º so that the springtension is applied to the cutter tip.Rotate the tool clockwise along the mandrel shaft untilthe cutter has moved over the length of pipe to be prepared and a continuous ribbon of polyethylene material has been removed.

Rotate the knob on thetop of the tool postthrough 90º so that thespring pressure isreleased. Remove thetool from the mandrelby depressing therelease button andcarefully draw over the shaft. Take care not to damage the prepared pipe surfaces.Remove the mandrel/sleeve assembly.

The pipe is now ready to be inserted into an electrofusion fitting.

Finally tighten themandrel by rotatingthe shaft in an anti-clockwise direction, using thespanner provided.

Do not overtighten.

M a k i n g t h e E l e c t r o f u s i o n J o i n t

Remove the Petrol-Line electrofusion fitting from itsbag and insert the preparedpipe fully in to the socket ofthe fitting.

To ensure correct insertion.It is advisable to mark the outsideof the pipes as shown

Care must be taken to preventmovement of the assembly duringthe fusion cycle. The use of pipeclamps will minimise the risk of accidental movement.Connect the Petrol-Line Electrical Control Unit (ECU) to a suitable power supply (3kVA minimum) and connect the leadsfrom the ECU to the terminals on the fitting.It does not matterwhich lead connector is attached to which terminal.

Durapipe manufacture both Manual and AutomaticElectrical Control Units for use with the Petrol-Linesystem.

Observe the fusion time shown onthe fitting. Switch on the ECU andpress the ‘UP’ button until therequired time appears in the LCDdisplay. Press the green ‘START’button to begin the fusion cycle.The LCD display will show theremaining time throughout the fusion process.

An audible bleep will be emitted each second followed by a seriesof rapid bleeps to indicate completion on the fusion cycle. Wherethe fittings have melt indicators, check that these have risen afterthe fusion cycle.

The joint must not be disturbed for the cooling period as shownon the fitting. Careful removal of the leads is acceptable to allowthe ECU to be use on subsequent joints.

The mushroom caps supplied with each electrofusion fittingshould be inserted in to the terminal shroud on completion of thefusion cycle and after the removal of the leads. These caps will,together with the fusion indicators (where fitted), remind theinstaller that the fusion process has been carried out.

Automatic ElectrofusionControl UnitsTechnology is now available whicheliminates the need to enter thefusion time manually. Special control units can be supplied withthe ability to read a bar code wherefixed to an electrofusion fitting. These machines have a ‘light pen’attached which the operator uses to input the data containedwithin the bar code.

Automatic control units also have data logging facilities to ensuretraceability of welding parameters. An output socket allows thedownloading of this information onto a computer database orprinter to obtain a complete record of the joints which have beenmade. This information can be downloaded daily, or on completion of the project. The units will store up to 200 operations.

Automatic ECUs have the ability to compensate for variations inambient temperature. No compensation is required between -5ºand +23ºC.

Bar CodesAll Petrol-Line electrofusion fittings are fitted with bar code labels.

Trouble-shooting procedure for Petrol-Line ECUsWhere problems occur during the fusion cycle, for example,because the input voltage to the ECU is to high or low, or theleads are not properly connected to the fitting, or they are damaged, the display will show an error message.Reference to the Handbook provided with each machine willexplain the cause of the displayed error either as letters or, inmachines of more recent manufacture, in words.

Where a transformed power supply is being utilised make surethat the power cable to the ECU is not of excessive length. Never extend the length of the leads from the ECU to the electrofusion fitting.

Note:Fusion indication is an aid to check that the fitting has been powered up but does not guarantee that a correctly fused jointhas been achieved. It is essential that the outer layer of the pipeis correctly removed by peeling or scraping and that the pipe iscorrectly inserted into the fitting socket. Pipe and fittings mustalways be correctly aligned and preferably clamped to prevent anymovement during the fusion cycle.

Transition connectionsWhere Petrol-Line Xtra coiled pipe (single wall or Secondary contained) is to be used, the transition connection componentsmust be correctly aligned with the end of the coiled pipe for theduration of the electrofusion process. Misalignment of the pipewithin these areas during the fusion process may result in displacement of the wires and distortion of the fitting.

Adjustments to pipe alignment/routing can be made after thefused joint has been allowed to cool using the inherent flexibilityof the pipe material.

Petrol-Line Xtra

Petrol-Line Xtra and Vent Xtra

Installation of Petrol-Line pipe systemsPetrol-Line systems manufactured by Durapipe are designed tomake the installation of fuel lines quicker, easier and morecost-effective than when using traditional materials.

Installation is as much a part of the costing equation as easeof maintenance and the cost of the pipe system materials.The great advantage with the installation of Petrol-Linesystems is the lightness and flexibility, coupled with itsdurability and totally secure jointing methods.

Trench excavationWhere pipework has to be laid in trenches, the installation of Petrol-Line systems requires minimal excavation.

Trench dimensions are normally governed by the pipe diameterand the prevailing site conditions. Trench widths should be asnarrow as possible, but typically not less than the outsidediameter of the pipe plus 250mm to allow for correct compaction of the sidefill.

It is acceptable to lay pipes directly on the bottom of thetrench, provided that the soil is uniform, relatively soft andfine grained and free from large flints, stones and other hardobjects which could damage the pipe wall. The trench bottomshould be brought to an even finish to provide consistentsupport to the pipes along their complete length.

Forecourt installationWhere pipes are to be laid side by side in wide/open trenches,as used in forecourt installations a minimum cover of 100mmis required and a minimum gap of 100mm should be leftbetween pipes.

100mm thickness of selected bedding material must beplaced below the pipe. Gravel or broken stone graded betweenfive and ten millimetres in size will provide suitable bedding since it requires little compaction. Coarse sand is alsoacceptable provided that the particle size is not less than3mm but care must be taken to ensure that such backfillcannot migrate as the result of high water tables. Where thispossibility prevails then the trenches must be lined with ageotextile material to prevent the migration.

Pipework must be laid to a gradient of 1:100 back to thetank. Heavy compaction equipment should not be used untilthe fill over the crown of the pipe is at least 300mm.

Any temporary levelling supports must be removed before thepipework is backfilled to prevent any damage to the piperesulting from uneven settlement.

Pipework laid in shallow depths

Protection must be provided to the pipe where it passes through a supporting wall or concrete manhole or chamber by using polyethylenesleeving to prevent the pipe being subjected to shear loads.

Where pipes are to be laid to shallow depths, the pipe must be protected by reinforced concrete to transfer any excessive loadingsresulting from the passage of heavy vehicles.

In exceptional circumstances, where pipework needs to be totally encased in concrete, the pipework should also be wrapped to preventdifferential stresses being applied to the pipe. Petrol-Line pipes are supplied wrapped in protective polyethylene sleeving, this sleevingcan be left in situ in these circumstances, and utilised to reduce the loading stresses.

Pipe bending

The minimum bend radius for Petrol-Line product lines (SDR11 wall sections) is 25 times the pipe outside diameter.

The safe bending radius for the Offset Fill and Vent pipes (SDR17 wall section) is 35 times the pipe outside diameter.

In the case of coiled pipe the above values apply only if the pipe is bent in the same direction as it was previously supplied.

Bending should be accommodated using the natural flexibility of the pipe. Avoid bending where there are joints.

Utilise the flexibility of the pipe.

NB. All existing pipework, adjoining tanks etc. must be drained,disconnected/isolated from source and purged with nitrogen beforeany electrofusion process is carried out to extend or re-route aPetrol-Line system.

Below ground The use of Mechanical type fittings is not allowed for belowgroundpipe systems.

The pipe stops incorporated in Durapipe Petrol-Line electrofusioncouplers are easily removed for the specific purpose of using thefittings for breaking into existing pipelines or making repairs.

Excavation should be carried out to expose sufficient pipe to allowthe ends to be peeled using a Petrol-Line Surprep preparationtool.

Measure the distance between the exposed pipe ends and cut asection of Petrol-Line pipe, to include any fitting, such as a tee,equal to the measured length less 10mm.

The marked surfaces of the inner pipe should then be scrapedusing a Petrol-Line Surprep preparation tool.

Remove the pipe stops in the coupler using a sharp blade, taking care not to damage the bore and the wires of the coupler.

Check that all the joint surfaces are clean and dry. Use Isopropanol wipes if necessary.

Place the couplers over the exposed lengths of the insertion pipe.Insert this pipe into the gap between the installed pipe. Slide thecouplers away from each other ensuring that the socket mouthsline up with the insertion marks on the inserted pipe.Carry out the correct electrofusion jointing procedures asdescribed earlier in this brochure.

Above ground - transition pointThe differences in length, resulting from the removal of atransition fitting can be accommodated by utilising a ‘Petrol-Line’Pecat® style Extended Transition fitting. These fittings are suppliedwith 750mm of pipe which can be shortened to suit the lengthrequired to effect a new connection.

All Petrol-Line Pecat® style transition fittings have continuity forthe control of static electricity.

It may be possible to use mechanical fittings (when available) to make a connection where space is restricted.

H a n d l i n g a n d S t o r a g e

Petrol-Line products are resilient, lightweight and easy to handle,however, care must be taken to avoid damage to the pipe sur-faces such as scuffing or gouging. In addition to the guidelinesset out below, the handling and storage of petrol pipes is coveredby the codes of practice issued in the IP Specification forUnderground Pipework Systems at Petrol Stations.

HandlingPipes A flat bed vehicle, free from sharp objects and projections shouldbe used for the transportation of Petrol-Line pipe systems. Whenlifting pipe bundles by crane, wide polypropylene slings must beused. Do not use chains, hooks or hawsers. When lifting pipebundles containing pipe lengths greater than six metres a load, a spreading beam should be used.

Allow for a certain degree of deflection or slight bending of thepipe bundles when loading or unloading. Standard six metre bun-dles may be handled using a fork lift, but longer lengths shouldbe moved using a side loader fitted with a minimum of four supporting forks, or using a crane fitted with a spreader beam.

Coils Coils of small diameter pipes are easily manhandled. Where fork-lifts are used to off load coils of larger diameter pipe, the forksshould be protected to avoid damage to the outer surfaces.

Storage

Badly stacked coils or bundles of pipe may slip or collapse caus-ing injury to personnel as well as damage to the product.The pipe sleeving intended to prevent ingress of contaminationshould be kept in place during storage.

Pipes - Individual lengthsPipe lengths stored individually should be stacked in a pyramidnot more than one metre high with the bottom layer fullyrestrained by wedges. Where possible the bottom layer of pipesshould be laid on timber battens at one metre centres to lift thepipe above sharp stones etc.

BundlesBundled packs of pipe should be stored on clear, level groundwith the battens supported by timbers. Bundled packs shouldnever be stacked more than three metres high.

CoilsCoiled pipe should be stored on firm level ground which has suit-able protection for the bottom of the coil. Facilities for safe lifting,movement and loading/unloading must be available.

Fittings Petrol-Line fittings are placed in heat-sealed polyethylene bags at the point of manufacture and then placed in cardboard boxes. The fittings must be kept in their boxes or packaging under cover in dry conditions until required foruse. Electrofusion fittings must not be removed from their plastic bags until immediately before use to prevent contami-nation and oxidation.

Pipe Petrol-Line pipes are supplied individually sleeved with colour coded polyethylene sleeving, to assist pipe identification,and to prevent oxidation and ingress of contamination during storage. (It is not essential to completely remove this sleev-ing prior to use.)

Releasing coils Petrol-Line pipes supplied in coils may be hazardous if released in the incorrect manner.The coiled pipe may be under tension and the incorrect release of the stored energy mayresult in the pipe uncoiling in a haphazard manner, particularly if the end of the pipe is notrestrained. Coiled pipes are secured by outer restraining bands with additional inner bandsbeing provided to secure the inner layers. Remove the bands carefully from the outer layerfirst so that only the length of pipe required is released.

Successive layers of pipe can then be released by removing the inner bands as the pipe isdrawn away from the coil.

ALWAYS

• Store pipes on flat, firm ground, able to withstandthe weight of the pipe/fittings and lifting apparatus.

• Keep pipe/fittings away from sharp objects suchas flints.

• Use wide non-metallic slings for lifting (ie nylon or polypropylene).

• Keep protective packaging intact until pipe/fittingsare required.

• Allow for some bending deflection of pipes duringloading and unloading. Ensure that lifting pointsare evenly spaced.

NEVER

• Drag individual pipes, bundles or coils.

• Throw/drop pipe/fittings from delivery vehicles.

• Use metal slings, hook or chains to offload pipes.

• Expose pipe/fittings to prolonged sunlight. (Product intended to be stored outside in excess of 12 months should be covered with black polyethylene sheeting and stored under cover.)

• Stack pipe bundles more than three metres high.
