The manufacturing process of stainless steel round pipes typically involves the following steps:
1. Material Selection: The process begins with the selection of the appropriate stainless steel grade based on the intended application and desired properties. Common stainless steel grades used for round pipes include austenitic, ferritic, and duplex stainless steels.
2. Billet Preparation: The selected stainless steel material is obtained in the form of billets or solid cylindrical bars. The billets are inspected for quality and defects before further processing.
3. Heating and Hot Rolling: The billets are heated to a high temperature and then passed through a series of rolling mills to reduce their diameter and form them into long, continuous strips known as “skelp.” This process is called hot rolling and helps shape the stainless steel into the desired pipe dimensions.
4. Forming and Welding: The skelp is then formed into a cylindrical shape through either the seamless or welded pipe manufacturing process:
5. Seamless Pipe Manufacturing: For seamless pipes, the skelp is heated and pierced to create a hollow tube known as a “bloom.” The bloom is further elongated and rolled to reduce its diameter and wall thickness, resulting in a seamless pipe. No welding is involved in this process.
