Seamless piping begins as a solid cylindrical hunk of steel called a billet. While still hot, billets are pierced through the center with a mandrel. The next step is rolling and stretching the hollow billet. The billet is precisely rolled and stretched until it meets the length, diameter and wall thickness as specified by the customer order.
Application Fields：
Seamless steel pipes are widely used in various fields, including the oil and natural gas industry, chemical engineering, construction, automobile manufacturing, machinery manufacturing, and electricity.
