Profile pipe used in many industries.
The nature of the cross section are rectangular and square shaped tubes.
Profile steel pipe with a notched cross-section (square, rectangular) are used in the manufacture of steel structures, construction, engineering industry, furniture production, etc.
This standard applies to steel pipes seamless hot-deformed and cold-worked, welded pipe, electrically welded cold-drawn, electrically welded gorjachekatanye, as well as pipes made by furnace welding.
Corresponds to GOST 8645-68 (118 kb)
The advantage of using such pipes:
Notes:
Cold-deformed pipes made from steel grades 10, 20, 35, 45
Welded pipes made from steel grades 08KP, 10, 10ps, 20, St2sp, St2ps, St4sp, St4ps, St4kp
Random length: 1.5 - 9 m; measuring: 5 - 9 m
Technical requirements - according to GOST 13663-86
Seamless cold-deformed pipes are produced heat-treated. Edit and trim the ends on the Addendum. Pipe size over 80x80 mm are supplied without edits and trim the ends
Welded pipes are produced without heat treatment
Quality control of the weld carried out by the instruments for nondestructive monitoring
