Cold forming:
Process is done at ambient temperature

Structrual hollow section manufacturing process:
Structural hollow sections are manufactured by seamless or by welding.
Welded sections manufactured by contiuous process.
Electric welded hollow sections are supplied without trimming the internal weld bead.

Non alloy steel heavy wall thickness pipe Delivery conditon:
Qualities JR, J0, J2 and K2 - Hot finished
Qualities N and NL - normalized. (normalized rolled)
- for accelerated cooling +DC
- for quenching and tempering +QT

Surface conditon:
The hollow sections have a smooth surface corresponding to the manufacturing method used; bumps, cavities or shallow longitudinal grooves resulting from the manufacturing process are permissible, provided the thickness is within tolerance.


End: Square cut

 

Inspection:

Chemical analysis

Mechanical tests (Tensile tests and Impact tests )

Visual inspection and dimensional check

Non-destructive testing(General Electric Welded Sections Submerged arc weled sections Retests,sorting and reprocessing)
