Compliance certificate

электросварные трубы профильные (квадратные, прямоугольные) производительElectric welded steel pipes, water and gas steel pipes, shaped steel pipes (rectangular, square) are produced at the electric pipe-welding mill “40-140” of the South Korean company “JUNGWOO EMC CO., Ltd”. The quality of pipe is confirmed by the compliance certificate GOST 3262-75, GOST 10705-80 , GOST 8639-82, GOST 8645-68. On customer’s requirement UMC LLC can carry out other additional quality tests.

Integrated Management System

лента оцинкованная, лента стальная оцинкованнаяThe company has developed and implemented an integrated management system (IMS), confirmed by the compliance certificate. The certificate confirms that pipes are 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.

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”.

Depending on quality characteristics electric-welded pipe is produced of steel grades as per group:
А – GOST 380-2005 (category 4 as per GOST 16523-97, category 1 as per GOST 14637-89);
Б – GOST 380-2005 and GOST 14637-89;
В – GOST 380-2005 (category 4 as per GOST 16523-97 and category 2-5 as per GOST 14637-89), GOST 1050-2013, GOST 9045-93.

Steel grades used for square and rectangular shaped pipe production are regulated with GOST 13663-86. According to technical requirements of normative documents pipe is produced:

– as per GOST 380-2005 of carbon steel grades St1sp, St1ps, St1kp, St2sp, St2ps, St2kp, St3sp, St3ps, St3kp, St4sp, St4ps, St4kp;

Description

Galvanized steel pipes are produced by electric-welding method, as a result elements are welded to each other with a weld seam. In order to restore anticorrosion properties UMC LLC coats weld seam with zinc by gas-flame spraying method.

Application field

Galvanized water and gas pipe. This high quality pipe is used in gas and water line systems. It is meant to be used only indoors.

Galvanized electric-welded pipe. This pipe type is produced of common steel. It is used only in machinery, agriculture and building spheres. Galvanized shaped pipe differs from all the other galvanized pipe types by the form of its section.

Advantages

Steel pipes are much-in-demand because of their high properties, especially because of their ability to resist high temperatures and withstand high pressure. Galvanized pipes are so high-strength that they do not even need any protection from mechanical damage.
