Product Description

ERW Grade API J55/A53(A;B)/16Mn/20# Non-Alloy Seamless Steel Pipes

Hot rolled seamless steel tubes

Hot rolled seamless steel tubes are classified into general steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel tubes, petroleum cracking tubes, geological tubes and other steel tubes.
It can destroy the casting structure of steel ingot, refine the grain size of steel, and eliminate the defects of microstructure, so that the steel structure is compacted and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent. Bubbles, cracks and looseness formed during casting can also be welded under high temperature and pressure.

Technological difference
1. Local buckling occurs in the section of cold-rolled shaped steel, so as to make full use of the bearing capacity of the bar after buckling; Local buckling of hot rolled section is not allowed.

2. The causes of residual stress in hot rolled steel and cold rolled steel are different, so the distribution on section is also very different. The residual stress distribution on cold-formed thin-wall section is curved, while that on hot-bound or welded section is thin film.

3. The free torsion stiffness of hot rolled section is higher than that of cold rolled section, so the torsion resistance of hot rolled section is better than that of cold rolled section.
