General Guidelines oFreeze Plug Application

General Design Criteria

CRYO Pipe Freeze Kits are recommended for use on uidssuch as water, water solutions with simple anti-corrosion and/

or anti-bacterial treatments with system pressures no greaterthan 300 psi and temperatures less than 110F. CRYO PipeFreeze applications on uids other than water and/or withpressures greater than 300 psi and temperatures greater than110F should never be attempted by an inexperienced person.Please consult our technical support for alternatives.

Nominal Pipe Sizes & Types

Both CRYO 102 & 204 Pipe Freeze Kits are recommended foruse on most all nominal pipe size ranges from 1/2 through4.0. The CRYO 102 Pipe Freeze Kit is specically designedfor nominal pipe size ranges from 1/2 through 2.0 as wellas 2-1/2 copper pipes. The CRYO 102 Pipe Freeze Kit isspecically designed for nominal pipe size ranges from 2-1/2

through 4.0. Both kits are intended for use with most alltype of pipe material in the 1/2 through 4.0 size range. It isrecommended that the applicator consult with the each pipemanufacturer for information regarding the effects pipe freezeapplications to each individual pipe material.

Pre-Job Safety Meeting

Every CRYO Pipe Freeze application should be preceded by apre-job project / safety meeting. It is important to plan out allaspects of the project between the pipe freeze applicator andthe project foreman.

General Pipe Conditions & Examinations

When selecting the section of piping for the freeze plug areait should be thoroughly examined for possible defects. CRYOPipe Freeze Kits should only be used on sections of pipingwhich are in good to excellent condition. Examinations shouldbe done on a minimum length of pipe of 3 x the CRYO PipeFreeze Chamber Length and the chamber should be placed inthe center of the examined area (Fig. 1).

During pipe examinations pay close attention to the bottoarea of the pipe since corrosion is often found on pipes whihave been insulated or buried. Some scaling or light rust mbe acceptable but be careful to avoid severe pitted or corrosareas of piping.

In rare instances pipe walls have been known to have seous defects within the internal wall material. If there is areason to suspect that a potential freeze plug location mighide such defects, the customer should conduct an NDT spection or other applicable testing method to assure that tpipe wall is sound. It is NOT recommended to perform a freeplug procedure on pipes which have a wall thickness less thmanufacturers listed design.

Chamber Placement: Recommended

Recommended placement of the CRYO Pipe Freeze Chamb

should be on a clear and unobstructed length of piping closer than 1-1/2 x the CRYO Pipe Freeze Chamber Lengfrom any pipe obstructions such as pipe welds or ttings. TCRYO Pipe Freeze Chamber should NEVER be placed direcon top of welds, pipe ttings or joints of any kind.(ie: CRYO 102 Pipe Freeze Chamber is 5 long therefore 1-1x 5 = 7-1/2) (Fig. 2).

Chamber Placement: Dead Head Obstructions

In regions that are prone to very cold winter months you mnd domestic piping systems that experience damage whexposed to extreme cold temperatures. This type of pipe daage is usually caused directly from the hydraulic forces cated by an unintentionally formed freeze plug as it expan

internally against a dead headed restriction such as a closvalve. This uncontrolled lateral freeze plug growth up againsdead headed obstruction may over pressure the piping uto a point where it could possibly damage the pipe. It is reommended that CRYO Pipe Freeze Chambers NOT be placany closer than 15 x the Pipe OD of any closed valves, bli

anges, pipe caps or any type of dead headed obstructio(ie: Pipe OD of 1-3/8 x 15 = 20-5/8) (Fig. 3).

However, if there is no other available option on the pipi

system within the recommended placement distance of 15the Pipe OD the applicator may utilize a pressure control appratus such as a hot tap saddle / nozzle equipped with a valvMost any pressure control point on the piping system shouallow any pressure buildup to be relived in a controlled maner (Fig. 4).

Chamber Placement: Flowing Headers / Branch

Pipes

CRYO Pipe Freeze Chambers should not be placed closer th15 x the Pipe OD from any active owing pipe. PerformiCRYO Pipe Freeze applications closer than the recommend

distance may result in the failure of the CRYO freeze plug establish. This is due to the uid movement in the mouth the branch pipe created from ow turbulence generated by towing pipe. This placement distance from owing headersonly a recommendation and may vary with each applicati(Fig. 5).

Heat Convection

Heat Convection ow currents are created inside pipes wa constant source of heat. Heat Convection ow currents amost always associated with vertical freeze plug applicationHowever, when there is a constant source of heat availablea horizontal pipe application it can play a critical factor in tfreeze plug formation. The heated uid within the horizon

pipe literally rises to the high point and is drawn into the coing formation of a developing freeze plug, cools down and thfalls to the low point of the pipe. This hot / cold reaction cates a convective ow resulting in a constant heat transfer thwill prevent or greatly slow the freeze plug formation (Figs& 6.1).

Pressure Relief Points

When installing a CRYO Pipe Freeze Chamber on a dead headed section of pipe having less than the recommendedlength, certain steps can be taken to eliminate the potential of pressure damage. A pressure control point can be utilizedby using an existing vent valve, periodically loosening a flange, stroking a downstream block valve or installing a hot tap

saddle all of which will allow a controlled means to relieve the increased pressure created from the expanding CRYOFreeze Plug. These orifices may also make good controlled drain down ports as well as re-refill ports upon completion.

Chamber Placement: Torch / Flame Cuts or Field

Welds

A recommended distance for torch cuts and eld welds from

freeze plugs should be no less than 3 x the CRYO Pipe FreezeChamber Length (Fig. 7). In some applications the distancecan be reduced (Fig: 7.1). However, close attention should begiven to the freeze plug and both the frost bands and tempera-ture readings should always be monitored during the repairprocess.


Fig. 7

Fig. 7.1

Fig. 8

Chamber Placement: Pipe Orientation

CRYO Pipe Freeze Chambers can be installed on pipes in ther a horizontal or vertical position. However the preferrrecommended installation position favors a horizontal sectiof piping due to the possible effects of heat convection fouin vertical pipe applications. This is especially true when tuid temperature is in the higher ranges.

Flow

Freeze plug applications require that ZERO FLOW be obtainin the system prior to the start of the freeze plug applicatioAttempting to achieve a workable freeze plug with any amouof ow is extremely difcult and/or impossible (Fig. 8).

Impact or Strain Generating Work Activities

When repair work is initiated in close proximity of the freeplug location it is recommended that the planned work on tpiping system not produce impact or strains such as bendior twisting action to the pipe. When possible the freeze plapplication should be located a safe distance from the woarea and well supported. Never place excessive weight onfreeze plug area. Always support the pipe.

Project Preparation

As much maintenance or pipe repair work should be compled prior to starting any pipe freeze project. This may inclusuch steps as exercising old ange bolts, pre-assembly of picomponents and having all necessary items staged. Each pi

freeze application is different and the applicator should codinate with the project foreman to complete any pre-projepreparation.

Work Area Safety Perimeter

The applicator should erect a sufcient Safety Perimearound all pipe freeze projects including the general work areliquid nitrogen tanks and equipment. Only pertinent projepersonnel familiar with the project should be allowed acces

PPE

The applicator should consult the area safety manager for sitespecic PPE requirements. Also see General Liquid Nitrogen

Safety for additional recommended PPE requirements.

Liquid Nitrogen Supply

Recommended liquid nitrogen tanks used in both CRYO 102and 204 pipe freeze applications should be LN-160 or LN-180 Low Pressure (22psi) Dewar Tanks. Please consult yourlocal area Welding Supply Company for availability, pricing andpertinent safety information.

Liquid Nitrogen Vapors: Job Site Ventilation

Liquid Nitrogen Vapors are generated by most typical pipefreeze operations utilizing Liquid Nitrogen. Liquid NitrogenVapors are heavier than air and CAN displace the oxygen in thearea if proper ventilation is not maintained. Area ventilation

can be maintained using one or multiple fans to keep fresh airmoving through the work area. The applicator should contacttheir Liquid Nitrogen supplier directly for a current MSDS andpertinent safety information. Also contact your safety managerand/or OSHA for recommended safety guidelines.

Liquid Nitrogen Vapors: Below Ground

Excavations

Areas which may not be dened as a conned space area (e.g.,very shallow ditches or immense excavations) may not requirespecial ventilation. However general work practices cautionthat low areas or exceptionally still air areas could have hazard-ously reduced oxygen levels. It is recommended to use force

air ventilation. Please consult with your safety department,oxygen monitor manufacturer, liquid nitrogen supplier and/orOSHA for specic safety details.

Liquid Nitrogen Vapors: O2 Monitors

It is HIGHLY recommended during all aspects of a pipe freezeplug applications that area worksite oxygen levels be moni-tored continuously by an OSHA approved oxygen monitor. Ac-cording to OSHA guidelines the breathable air should never beless than 19.5%. Please consult with your safety department,oxygen monitor manufacturer, liquid nitrogen supplier and/orOSHA for more details.

Halon, Smoke & Flame Detectors

Be aware of halon and smoke detectors in the immediate area.Nitrogen vapors have similar characteristic as smoke and willactivate these devices. Also be aware of re/ame detectorsand be careful not to upset them during the procedure. If nec-essary you may want to consult with the project site coordina-tor to de-activate these devices.

Temperature Monitoring Equipment

It is HIGHLY recommended to utilize temperature monitoriequipment on all freeze plug procedures. CRYOLATOR PiFreeze Products has developed a Freeze Plug Temp MonitoriKit specically for pipe freeze applications. (part # ACL-601015-C). Please consult our sales staff for additional informtion (Fig. 9).

Conrmation of Freeze Plug

Once both the Frost Band and Temperature criteria have be

meet it is time to check the integrity of the newly formFreeze Seal Plug. Open a controlled means of drain on tdrain down side of the Freeze Seal Plug. (i.e: controllmeans may be a valve or other mechanical means which cbe isolated as needed) (Fig. 10).

SIGN OF GOOD PLUG: During the drain down process the PiEnd Thermocouples Temperature readings maintain tempeture reading of no less than -35F and continue to drop as tuid is drained.

SIGN OF GOOD PLUG: During the drain down process tFrost Band growth distance continues to maintain and/or grin length as the uid is drained. Normal Frost Band growth

1-1/2 to 2-1/2 in length out from the chamber end (Fig. 1

SIGN OF GOOD PLUG: During the drain down process tcalculated uid drain amount is completely emptied from tpiping system.

SIGN OF BAD PLUG: During the drain down process the PiEnd Thermocouples Temperature readings start to increaand continue to increase beyond the recorded drain down teperature start points. Immediately stop the drain down and DNOT proceed. The plug is not solid or workable.

Fig. 9


9/30




SIGN OF BAD PLUG: During the drain down process the FroBand growth distance starts to melt and shorten from the etablished start points inward to the chamber ends. Immeately stop the drain down and DO NOT proceed. The plug is nsolid or workable (Fig. 12).

SIGN OF BAD PLUG: During the drain down process the cculated uid drain amount is exceeded and uid continues drain.

NOTE: All (3) of the GOOD PLUG SIGN criteria should met before proceeding.

NOTE: If at any time during the drain down process (1) the (3) BAD PLUG SIGN criteria is noted the drain doSHOULD BE STOPPED and the situation be evaluated by tapplicator.

Equalization & Warm-UpBefore a freeze plug is allowed to thaw it is highly recomended that the downstream piping section be relled aif possible the pressure equalized to the upstream side. Thpractice may prevent possible system damage which may ocur from the sudden release of a downstream freeze plug. Sytem crossover piping or hose-jumped hot taps may be utilizto equalize the pressure across the freeze plug. Additioncaution should be given to the possible pipe travel of a looened/thawed plug once it has released from the internal piwall. A owing freeze plug could damage downstream pipelipumps and equipment. To accelerate the thawing process ofreeze plug the applicator may remove the CRYO Pipe FreeChamber and using a commercial heat gun to apply direct he

across the freeze plug to accelerate the thawing process. exible feed hoses and CRYO Pipe Freeze Chambers should warmed above 0* F before being removed and exed.

Final Responsibility

CRYOLATOR Pipe Freeze technical personnel may at timconduct preliminary telephone, email, off site project assesments and project evaluations for our clients. However the cutomer is responsible for all pipe inspections, potential freeplug locations and any damage caused to their piping systemas a result of pipe freeze applications.

Liquid NitrogeInformatio

General

Liquid nitrogen is inert, colorless, odorless, non-corrosive,nonammable, and extremely cold. Nitrogen makes up themajor portion of the atmosphere (78.03% by volume, 75.5%by weight). Nitrogen is inert and will not support combustion;however, it is not life supporting. Nitrogen is inert except whenheated to very high temperatures where it combines with someof the more active metals, such as lithium and magnesium, toform nitrides. It will also combine with oxygen to form oxidesof nitrogen and, when combined with hydrogen in the presenceof catalysts, will form ammonia.

Health Effects

Although nitrogen is nontoxic and inert, it can act as a simpleasphyxiate by displacing the oxygen in air to levels below thatrequired to support life. Inhalation of nitrogen in excessiveamounts can cause dizziness, nausea, vomiting, loss of con-

sciousness, and death. Death may result from errors in judg-ment, confusion, or loss of consciousness that prevents self-rescue. At low oxygen concentrations, unconsciousness anddeath may occur in seconds and without warning. Personnel,including rescue workers, should not enter areas where theoxygen concentration is below 19.5%, unless provided with aself-contained breathing apparatus or air-line respirator.

Containers

Fig. 13 shows a typical cryogenic liquid cylinder. Cryogenicliquid cylinders are insulated, vacuum-jacketed pressure ves-sels. They come equipped with safety relief valves and rupturediscs to protect the cylinders from pressure build-up. These

containers operate at pressures up to 350 psig and have ca-pacities between 80 and 450 liters of liquid. Product maybe withdrawn as a gas by passing liquid through an internalvaporizer or as a liquid under its own vapor pressure (Fig. 13).

Handling and Storage

Store and use this product with adequate ventilation. Do nstore in a conned space. Cryogenic containers are equippwith pressure relief devices to control internal pressure. Undnormal conditions, these containers will periodically vent prouct. Do not plug, remove, or tamper with any pressure reldevice. Never allow any unprotected part of the body to comin contact with uninsulated pipes or equipment that contacryogenic product. The extremely cold metal will cause tesh to stick fast and tear when one attempts to withdrfrom it. Use a suitable hand truck for container movemeContainers should be handled and stored in an upright potion. Do not drop, tip, or roll containers on their sides. Do nremove or interchange connections. Contact the vendor if yexperience any difculty operating the container valve or wthe container connections. Discontinue use. Use the propconnection.

Use piping and equipment designed to withstand the presures to be encountered. On gas withdrawal systems, usecheck valve or other protective apparatus in any line or pipifrom the container to prevent reverse ow. To prevent crygenic liquids or cold gas from being trapped in piping betwevalves, the piping should be equipped with pressure reldevices. Only transfer lines designed for use with cryogenliquids should be used. Some elastomers and metals may bcome brittle at low temperatures and will easily fracture. Thematerials must be avoided in cryogenic service. It is recomended that all vents be piped to the exterior of the buildior to a well ventilated indoor space.

NOTE: It is recommended Liquid Nitrogren feed pressure limited to 22psi. This will prevent the CryoFoam ChambGaskets & Pipe Seals from experiencing an LN2 blowofailure.

Personal Protective Equipment (PPE)

One must be thoroughly familiar with the properties and safetyconsiderations before handling a cryogenic liquid and its asso-

ciated equipment. The eyes are the most sensitive body part tothe extreme cold of the liquid and vapors of cryogenic liquids.The recommended personal protective equipment for handlingcryogens includes a full face shield over safety glasses, loose-tting thermal insulated or leather gloves, long sleeve shirts,and trousers without cuffs. In addition, safety shoes are rec-ommended for people involved in the handling of containers.Depending on the application, special clothing suitable forthat application may be advisable.

A special note on insulated gloves: Gloves should be loose-ting so they are able to be quickly removed if cryogenic liquis spilled on them. Insulated gloves are not made to permit thands to be put into a cryogenic liquid. They will only provishort-term protection from accidental contact with the liquIn emergency situations, self-contained breathing apparat(SCBA) may be required.

Our Hot TappingService utilizes various sizes of drilling / pipetapping machines to perform our procedure of cutting holes inoperating pipelines while under pressure allowing for new branchconnections on the original piping systems. The process is donewithout any product leakage or interruption to ow. The compo-nents for a typical hot tap application include a tting designed tocontain system pressure, a valve used to control the new connection,and a drilling machine used to make the hot tap. We perform pipetaps on all types of pipe. Special applications are available uponrequest.

Our Line Stopping Service uses special Pipe PluggingMachines to achieve temporary mechanical ow stops onan operating pipeline. Mechanical Line Stops can be usedto plug piping systems for repair, alterations, or relocations.Temporary Mechanical Line Plugs can also be conguredwith bypass piping around the plugged section of pipe tobe repaired, allowing for uninterrupted product / systemow.
