For the construction of trunk, oil and gas lines the ÒÌÊ produces a wide range of longitudinally and spirally welded pipes of large diameter compliant with Russian and international standards GOST, TU and API.

The large diameter pipes manufactured by Volzhsky Pipe Plant (VTZ) and Seversky Tube Works (STZ) (under the SP TMK-CPW). VTZ has a longitudinal mill of the Swiss company Haeusler, producing pipes 508-1422 mm in diameter made from sheet steel, as well as spiral line producing pipes 530-1420 mm in diameter made from steel coils.

STZ is equipped with Corinth Pipe Works mill that allows producing pipes 508 mm and 530 mm in diameter.

LARGE DIAMETER PIPES PRODUCTION

The convenient geographical position of Volzhsky Pipe Plant - availability of railway lines and motor road, proximity to the sea and river routes - enables the plant to make deliveries to the customer accurately and on time. The advantage of the geographical position of Seversky Tube Works is its proximity to the oil and gas provinces Khanty-Mansiisk autonomous okrug ,Yamalo-Nenets autonomous okrug and Siberia.

CORINTH PIPE WORKS MILL ALLOWS PRODUCING PIPES 508 MM AND 530 MM IN DIAMETER


8 9

In December 2008, as a part of the Volzhsky Pipe Plant strategic investment program, the new 650 thousand tons Haeusler mill was successfully launched at Volzhsky Pipe Plant. It can produce LSAW pipes with diameters of between 508 mm and 1420 mm in diameter with a wall thickness of 8 to 42 mm and strength grade up to K65 according to the Russian standards, as well as longitudinally welded large diameter pipes with diameters ranging from 508 to 1422 mm and wall thickness from 7.9 to 42 mm, and strength grade up to X80 according to API Spec 5L standard. The process procedure with the use of the three roll forming method, followed by submerged arc welding and expansion is the most effective way of production of the trunk longitudinally welded pipes of large diameter.

Quality policy

Compliance with high quality standards of the output is the basic condition to win consumer loyalty, therefore ÒÌÊ seeks to follow the best international management practice in all aspects of its activities.

All TMK plants have the Quality Management System certified as compliant with the international standard ISO 9001-2008 requirements.

The Company takes a responsible approach towards the environmental protection issues, social obligations, and is fully engaged in addressing the environmental issues in the region.

2. LONGITUDINALLY WELDED LARGE DIAMETER PIPES PRODUCTION

The plants successfully employ the Environmental Management System certified as compliant with the international standard ISO 14001: 2004 requirements.

All large diameter pipes shall undergo non destructive examination with the use of ultrasonic, X-ray and magnetic particle methods, as well as hydrostatic testing.

The spirally welded large diameter pipes production facilities include 4 mills, producing pipes 530-1420 mm diameter made of coil steel with wall thickness of 6-16 mm.

Spirally welded large diameter pipes have been designed for the construction of trunk oil and gas pipelines, infield, general-purpose pipelines, heat network and nuclear power plants pipelines. The spiral large diameter pipes are also used for the cold bending curves (CBC), shells (pipe in pipe), high and low pressure conduits, tongued-and-grooved cost protection structures.

They are produced by submerged arc welding.

The application of improving volume heat treatment (quenching + tempering) allows producing pipes with strength grade up to K65 as per GOST and X80 standard API. After heat treatment the base metal, weld metal, heat affected zone of welding become homogeneous in structure. At the same time, the differences in the mechanical properties of the pipe structural elements are eliminated, the simultaneous increase in strength and metal viscoplastic response takes place.

Spirally welded large diameter pipes production

3. SPIRALLY WELDED LARGE DIAMETER PIPES PRODUCTION

The spirally welded large diameter pipes undergo hydrostatic tests and the full cycle of non-destructive testing, including:

ultrasonic testing of the skelp for lamination; ultrasonic and X-Ray-TV testing of the weld seam; chamfer and pipe ends ultrasonic testing.

The use of spirally welded pipes reduces the losses through pipelines destruction, since the spiral weld prevents the spread of the longitudinal main cracks in the pipelines (the most hazardous destruction). The spirally welded pipes have the increased bending, tensile and compressive strength.

VTZ OJSC production facilities allow applying the following types of external anticorrosion coatings on the pipes (including S-v coatings)

Two-layer polyethylene or polypropylene Three-layer polyethylene or polypropylene

Coatings are applied to the external surface of welded and seamless pipes 114-1420 mm in diameter. The ambient temperature during operation range from -40°C to + 80°C. The quality of pipeline coating ensures their safety during underground laying for at least 30 years.

6. INTERNAL COATINGS OF PIPES

VTZ production facilities enable to apply the following types of inner coatings on the pipes:

Smooth (anti-friction) Protective (Amercoat, Scotchkote)

The internal coating may be applied both before and after external coating application.

The internal flow-coat is designed for the increase of carrying capacity due to reducing losses during transportation, it also contributes to the inner surface protection of the pipes against atmospheric corrosion during transportation, storage and construction and installation works execution. The coating is applied on the pipe 530-1420 mm in diameter.

The permissible ambient temperature during the continuous operation of gas pipelines ranges from -45°C to + 60°C. The coating quality ensures the life cycle of pipelines for at least 10 years.

The internal protective coating (Amercoat, Scotchkote) is designed to protect the inner surface of pipes from corrosion in water pipelines, including drinking water pipelines, agricultural water supply pipelines, sewerage systems. The coating is applied on the pipes 630-1420 mm in diameter.

The permissible ambient temperature during the continuous operation of pipelines ranges from 45°C to + 60°C, operated medium temperature - from + 5°C to + 50°C. The coating quality ensures the life cycle of pipelines for at least 10 years.
