Grade API J55/A53(A;B)/16Mn SCH40 Hot Rolled Seamless Steel Pipe
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.
