Seamless Tube
Seamless Mechanical Tubing
Our seamless mechanical tubing is produced through an extrusion process where a solid steel billet is heated and drawn over a piercing rod. This method creates a hollow shell without a weld seam, resulting in a tube that handles higher internal pressures and offers superior structural integrity. Unlike standard pipe, our seamless tubing is manufactured to precise outside diameter (OD) and wall thickness specifications.
