Compliance certificate

электросварные трубы профильные (квадратные, прямоугольные) производительProduction of longitudinal 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 longitudinal pipe is confirmed by the compliance certificate GOST 10705-80. On customer’s requirement UMC LLC can carry out other additional quality tests.

Integrated Management System

лента оцинкованная, лента стальная оцинкованная The company has developed and implemented an integrated management system (IMS), confirmed by the compliance certificate. The certificate confirms that longitudinal steel pipe GOST 10705-80 (GOST 10704-91) 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 electric-welded 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 operation and welding of longitudinal pipes.

Description

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.

Comparison

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.
