Square steel pipe
Uraltrubprom produces longitudinal electric-welded pipes of square section with sizes from 80x80 to 500x500 mm and wall thickness from 3 to 22 mm.
JSC Uraltrubprom produces square pipes only from coiled steel at ERW mills. Square section pipes are welded with high-frequency currents (HFC).
Square section pipes are applied in construction industry to manufacture metal structures of various buildings, constructions as support elements. Square section pipes are used in machine building as an element of the construction of various equipment, in particular for the manufacture of frames for trucks and tractors, elements of the frame of tank containers, etc.
Name: square welded pipes, shaped pipes, steel bent closed welded sections, bent welded pipes, cold-bent steel section, pipes of square section.
Shaped pipes of square sections produced by Uraltrubprom meet requirements of the following standards:
GOST 30245, GOST 25577, GOST 13663, GOST 8639, GOST 32931
EN 10219-1, EN 10219-2, ASTM A500/A500M.
Besides, Uraltrubprom produces electric-welded square sections with additional TU requirements: ▼
TU 1303-004-12281990. Steel bent closed welded sections for elements of the frame of tank containers. Operating temperature of exploitation is in the range from -40°С to +50°С.
The basic standard requirements can be supplemented or changed with considering of production capacities of the equipment:
- non-standard geometrical parameters (length, width, and height of section, wall thickness);
- additional testing, inspection;
- additional treatment (removal of burr, coating, completion), etc.
Delivery, shipping, order.
- Pipes are shipped with motor and railway transport. Self-delivery is possible.
- Pipes are produced under specific order.
- We accept only wholesale orders from 20 tons (one item or combined order).
