Hot-rolled steel pipes are divided into general steel pipes, low- and medium-pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes, and other steel pipes.
Hot rolled steel pipe: Hot rolling is relative to cold rolling. Cold rolling is rolling performed below the recrystallization temperature, and hot rolling is rolling performed at a temperature above the recrystallization temperature.
The advantage of hot rolled steel pipe:
Hot rolled can destroy the ingot's casting structure and refine the grain of the steel. And eliminate the defects of the microstructure, so that the steel structure is dense 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, the bubbles, cracks and looseness formed during pouring can also be welded under high temperature and pressure.

Our hot sale product ASTM A106 steel pipe can be produced by hot rolled processing the diameter above 2 inch. The size less than 2 inch is usually produced in the form of cold-drawn. Recently we exported one batch of carbon steel hot rolled pipe with big quantity to South Africa, the quality is good and confirmed by customer.
