1. Production process of seamless steel pipe

Seamless steel pipes are made by heating steel billets and then perforating, rolling, and finishing them. Among them, piercing is the first step in the production of seamless steel pipes, usually using hot piercing or cold piercing processes. During the piercing process, the steel billet is heated to a high temperature and then pierced through a piercing machine to form a preliminary steel pipe shape. Next, the steel pipe goes through multiple rolling processes to gradually reach the required outer diameter and wall thickness. Finally, the steel pipe undergoes finishing treatments such as cutting, heat treatment, flaw detection, etc. to ensure the quality and performance of the steel pipe.
