ГОСТ 8645-68

JSC "Uraltekhmarket" offers Pipe rolling, appropriately ГОСТ 8645-68.

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:

  1. The reduction of the amount of metal in the object.
  2. Increased speed and ease of installation buildings and structures.
  3. Rectangular tube easy to lay on flat surfaces.
  4. To facilitate the installation can wire for welding.
  5.  The increase in corrosion resistance.
  6. Compliance with sanitary and hygienic norms, not challenging sanitization and disinfection.
  7. Just processed by means of fire protection and compliance with fire safety standards.
  8. Tubes can easily replace other types of metal (steel I-beam, channel, angle).
  9. Steel pipe can deliver the most extraordinary design and architecture ideas.
  10. Automatic and semi-automatic arc welding will be able to help you to an unusual and complex design that will withstand complex loads.

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
