All the company locations are certied UNI EN ISO 9001:2008.

Moreover, Commerciale Tubi Srl IRIPE is a member o the UNSIDER, Italian standards unication board orthe steel sector, and is registered since 2004 with the Industrial Association o the Province o Venice withinthe Conederation o Italian Industries (Condustria).

Commerciale Tubi Srl has been operating since 1974 in the steel pipes market, with the objective o oering aservice ever more comprehensive and in line with market demand.

Since 2003 Commerciale Tubi Srl IRIPE has expanded its territorial presence and logistic capacity, taking overthe warehouses o the subsidiary companies Siderandes Srl in San Giorgio di Mantova and C.S.I. CommercialeSiderurgica Italiana Srl in Calderara di Reno (BO).

The technological development o the company continued in 2005 with the launch oIRIPE, a modern plantthat includes two new and ecient acilities, the rst or the application by hose extrusion o an external threelayer polyethylene coating to steel pipes with diameters ranging rom 3/4 to 12 in 6 or 12 metre lengths, andthe second acility that allows or the internal application o a thick coat o epoxy paint specially designed ormaterials intended to convey drinking water.

Today the company employs a total o about 60 people shared among the three operational sites, as well as asta o agents and collaborators. The company warehouses cover a total surace o over 80.000 square meters,hal o which covered, thus allowing the company to stock a wide range o merchandise, with over 20.000 tonso material and products available.

Thanks to its cooperation with the major Italian and European manuacturers, Commerciale Tubi Srl IRIPE hasthe capacity to sign trade agreements that provide or scheduled supplies with considerable advantages botheconomically and in terms o fexibility and speed o delivery.

Today the investment necessary or a water or gas conveying system is particularly high and the return oninvestment generated by their use requires an average lie o 20 years. Thus the environmental conditionsin which the pipelines operate are o major importance and the choice o anti-corrosive protection to beadopted, depending whether the piping is laid above or below ground, immersed in resh or salt water, becomesundamental. All piping, not just steel, is in act subject to corrosion, i.e. the natural progressive deteriorationcaused by mechanical and electrochemical actions which can go as ar as destroy the metals in contact with acertain environment.The laying grounds and stray currents that originate rom direct-current installations are the major causes o pipecorrosion rom external sources. In both cases, because o the direct current fow rom the pipe to the externalenvironment (cathode zone), the result is electrolytic metal dissolution and ormation o corrosion craters.

soil Corrosivity

The corrosivity o a soil depends on its chemical characteristics (acidity and alkalinity, etc.), physicalcharacteristics (air permeability, porosity, water absorption capacity, electrical resistivity, etc.) and biologicalcharacteristics (presence o sulate reducing bacteria, etc.). Electrical resistivity, whether directly or indirectlylinked to the physical and chemical characteristics o the terrain, can be assumed as an index o its corrosivity.Clay soils and those containing chlorine and sulphate ions, such as salty soils, are highly corrosive.

general CharaCteristiCs o anti-Corrosive Coatings

In recent years remarkable progress has been made in anti-corrosive coatings in order to satisy the highqualitative and saety standards required by the market.The main actors to take into consideration in the choice o the type o coating are: Resistance and durability Stability at working temperatures

Capacity of adhesion to steel Ease of repair in case of damage Pipe laying characteristics Working costs relative to interventions on the coating.

Corrosion

For Commerciale Tubi, IRIPE represents technological excellence and the fagship o its machining processes.In a modern, 4.000 square meter building entirely supported by compressed air and equipped with overheadcranes or pipe handling, the ollowing production lines have been installed:

an automatic production line for the application by hose extrusion of a three layer external polyethylenecoating in accordance with the major quality standard regulations, such as UNI, DIN, NFA, CANADIAN,as well as regulations specic to particular international, municipal or European projects.

a second automatic p roduction line that allows for the internal sandblasting a nd coating of pipes withepoxy paint adapted to the conveying o drinking water or with antiriction paint or the transport o gas.

This modern plant is surrounded by a 14.000 square meter cemented area which enables the sae storage o thebare pipes prior to coating and o the coated pipes ready or shipping.

the iripeanti-Corrosive Coating

The polyolen coating (polyethylene and polypropylene) is applied to the pipes by a hose extrusion process(diameters rom to 12).Thanks to the use o modern techniques and the choice o raw materials, the ollowing results can be obtainedrom three layer external coatings and internal epoxy coatings: High resistance to corrosion caused by uids, gases and chemical products High resistance to impact and hardness tests High dielectric properties Extremely high adhesion values (tearing) over a wide temperature range Use of polyolen coatings for a wide temperature range (polyethylene up to 80C and polypropylene

for offshore and over 80C)

Excellent resistance to the deformation caused by the realization of curves Ease of repair of possible damage occurring during pipe transport or laying.

The unprocessed pipes arriving rom the storage area are loaded onto theproduction line by an overhead crane.The pipes are then controlled one by one in order to record their traceabilityand to check or any traces o grease, oil, or damage.

Prior to the sandblasting phase, the pipes are pre-heated in a gas urnacein order to eliminate any residual moisture and respect the parametersprovided in the sandblasting specication. The pipes are then sandblastedwith an angular-shaped metal grit in order to obtain the specied degreeo roughness and surace cleanliness. The sandblasting cabin is protectedand sound-prooed, with a reservoir or ltering and recycling dusts.

Ater an additional surace control, the sandblasted pipes are joinedin order to orm one single pipe on the coating line and are thenorwarded to the pre-heating process. The pipes are pre-heated inan induction heating coil, with the purpose o raising the suracetemperature o the steel to the temperature required or a correctapplication o the epoxy powder (primer). The temperature isconstantly monitored or each pipe.

The application process o the rst layer (primer) species the use o anautomatic spraying system composed o electrostatically charged sprayguns. The control and adjustments o each spray gun is automatic. Thetwo subsequent layers, adhesive and top coat (PE), are applied with asingle extrusion head composed o two central blocks that distribute the

products on the entire pipe in a uniorm manner.In the event o an axial misalignment between the extrusion head andthe pipe, the process includes an automatic alignment system.

The pipes are lined with blue or yellow coloured stripes based on theintended application (water or gas).In addition, each pipe is marked on its entire length with a continuoustext that reports the bare steel pipe and coating specications.

The coated pipes are immediately immerged in a water cooling tankthat reduces the temperature o the pipes in order to avoid any possibledeects due to a sotening o the coating.

Cut-back consists in the removal o a 100-150 mm length o coatingrom the pipe ends. This process uses abrasive steel brushes that alsoorm the appropriate bevel at the extremity o the coating.

The Holiday-Detector controls the continuity o the coating on theentire surace o the pipes, by applying a 25-30 kV tension on theentire circumerence. This control is conducted continuously on 100%o the pipes.

At the end o the production line, the pipes are stacked by an overheadcrane into hexagonal bundles in order to maximize the nal storage.They are then handled with ork-lits and stacked in the storage areaready or shipping.
