The start-up of ERW mill «630» and the whole line for pipe production took place at “Uraltrubprom”, JSC (Urals Pipe Works) on 29th of May, 2009.
The new line for ERW pipes production was manufactured and installed by Japanese companies. This line is the biggest one of Japan manufacture in Europe. The production capacity of new equipment is 400 000 tones of pipes per year.
Some unique technologies which have no analogues in Russia are included in the processing line, such as forming mill «630», designed and patented by Japanese company. There is no other mill line in the world excelling this one in technological characteristics and operation stability.
The distinctive feature of new equipment is the pipes production technology. For the first time in Russia and only at “Uraltrubprom”, JSC pipes of big diameter will be produced using coiled steel as raw material, herewith maximum wall thickness will be 22 mm. Generally pipes with diameter from 630 mm are produced only from sheet metal. Moreover the welding will be high frequency (ERW pipes) as opposed to other Russian pipe mills which produce only SAW pipes.
The above mentioned mill line also will comprise of slitting line, pipe finishing line, engineering utilities and auxiliary systems.
Main types of products to be produced using new mill line:
Round pipes 219-630 mm (GOST 10704, GOST 20295), 219,1- 609,6 mm (API 5L-2004), wall thickness 3-22 mm, steel with strength grades from X42 up to X80.
Structural pipes of round section 219-630 (GOST 10704, GOST 20295-85), 219,1-630 (EN 10219-1:1997, EN 10219-2:1997, EN 10220:2002), wall thickness 3-22 mm, steel grades with yield strength up to 550 MPa.
Square hollow sections 180x180, 500x500;
Rectangular hollow sections 220x140, 600x200
wall thickness 3-22 mm, steel grades up to 550 Mpa (GOST 30245-2003, GOST 25577-83, EN 10219-1:1997, EN 10219-2:1997, EN 10220:2002).
Casing 219,1-508, wall thickness 3-22 mm, steel with strength grades up to N80 (API 5L-2004), annual production quantity is 50 000 . (in prospective development)
“Uraltrubprom”, JSC will become the only plant in Russia and CIS countries with the widest size range of square and rectangular hollow sections from 80x80 up to 500x500 and 600x200 mm.
