Gas and water pipe produced by the company in zinkcoated and noncoated types.

Steel grades

Gas and water pipe is produced of steel grades as per GOST 380-2005 “Common quality carbon steel. Grades” and GOST 1050-2013 “Metal products from no-alloyed structural quality and special steels. General specification”.

Pipe intended for production of gas and water system parts is produced only of steel grades as per GOST 1050-2013.

Compliance certificate

водогазопроводные, стальные трубы, электросварные трубы профильные (квадратные, прямоугольные) производительProduction of gas and water pipe is carried out at the electric pipe-welding mill “40-140” of the South Korean company “JUNGWOO EMC CO., Ltd”. The quality of UMC gas and water pipe is confirmed by the compliance certificate GOST 3262-75. On customer’s requirement UMC LLC can carry out other additional quality tests.

Integrated Management System

качественные трубы и ленты стальные сертификатThe company has developed and implemented an integrated management system (IMS), confirmed by the compliance certificate. The certificate confirms that water and gas steel pipe is produced in accordance with the requirements of GOST ISO 9001-2011 (ISO 9001:2008), GOST R 54934-2012 (OHSAS 18001:2007), GOST (ISO 14001:2004).

Weld seam test

Weld seam test of water and gas steel pipes is carried out at electric magnaflux plant UMD-101M. Plant operation principle is based on creating of static magnetic field in tested objet and transformation of the field changes (leakage) into electric signal – defect signal. The leakage is generated by geometric and electromagnetic oscillations of the system “converter-product”, i.e. by defects such as steel discontinuity (see pict. 1).

Defect detector works in continuously-automated operating mode and while pipe moves it carries out non-destructive control testing of weld discontinuity, it also registers defects and informs the operator about the quality of weld seam, its deseaming and geometry. Immediate receiving of information shows the welder correctness or incorrectness of pipe forming and welding operation.

Not presented dimensions of gas and water pipe can be agreed individually.

Dimension tolerances are regulated by par. 1.3 of GOST 3262-75.

Mechanical properties

Water and gas steel pipe GOST 3262-75 is produced without regulated chemical composition and mechanical properties.

Mechanical properties of the steel as per GOST 1050-2013 used for water and gas pipe production meet the characteristics presented in the table:

Packaging material

Black packaging steel strap (waxed and painted) 32*0,8 mm. Packing interval – 0,5 m from package end and further on at the distance of at least 1,5 m. Packing is carried out by import equipment Signode, providing ideal tension and package safety. Product transportation is possible without using bolsters. On the customer’s agreement pipe can be oiled.

Package length: 6; 11,7 and 12m (other dimensions can be agreed individually).

Pipe products resulting from strip welding are called electric-welded. Round electric-welded pipe is also often called gas and water pipe, as it is widely used in heating, gas and water systems. With few exceptions, pipe manufacturers produce longitudinal electric-welded pipes. Round pipes of minor diameter can be produced thin-walled or casing thick-walled. The price on electric-welded pipe mainly depends on price and demand of hot-rolled strip.

Application field

Pipe products are used in different industrial spheres: machinery; furniture and metalware production; construction etc. However, the main application is transportation of liquid and gas substances: water for drinking and heating, hydrocarbon and other chemical agents. Pipeline systems are very efficient for liquid transportation because of their strong ability to withstand pressure up to 16 mPa.


Longitudinal electric-welded pipes as per GOST 10705-80 and 10704-91 are also known as water and gas pipes. However, it is correct to say water and gas pipe in relation to the pipe GOST 3262-75. Water and gas pipe GOST 10704-91 in comparison to the pipe GOST 3262-75 has outer diameter dimensionality, rather than nominal bore dimensionality.
