Seamless Pipe: A Seamless/ERW Pipe is a tubular section or hollow cylinder used primarily to convey substances, which can flow the following: liquids and gases, slurries, powders, masses of small solids. Steel pipes may not necessarily be a circular cross-section.

The two processes involved in manufacture are: 1. Cross roll piercing and elongation or 2. Plug mill process.

Seamless pipes are shaped by rolling a preheated billet between offset rolls. The seamless pipe is then finished to dimensional and wall thickness specifications in sizes from 1/8 inches to 26 inch OD. At high rolling speeds / pressures, the arrangement creates stress in the center, that facilitates its piercing with a pointed bar or plug, to generate a tube shell.

STEADFAST offers various schedule and grades of Seamless Pipe such as API, DIN and ASTM.
