It is available to manufacture pipeline, vessel,equipment,pipe fittings and steel structure.

Manufacturing process of the hot rolled seamless steel pipe

We produce technology advanced hot rolled seamless steel tubes using continuous tube rolling mills. The hot rolling process consists of steel billet → heating → punching → three-roller skew rolling → tube knockout → tube diameter reducing → cooling → semi-finished pipe → straitening → water pressure test → labeling → warehouse entry.

Features

Our hot rolled steel pipes offer various outstanding features and comparative advantages, as is manifested by the following. In our way of manufacturing the hot rolled steel pipe, the cast structure of steel ingot can be broken, the grains of steel are refined, and the defects of the micro-structure of steel are eliminated, resulting in improved mechanical properties and denser micro-structures of the steel product. For specifications of our hot rolled steel pipes, please see the form attached.
