Seamless (SMLS) Steel Pipe is made from a solid round steel 'billet' which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. The seamless pipe is then finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 26 inch OD.

Interpipe can secure and process your Seamless Pipe order, including specialized requirements and cut to length up to 50 feet in length

ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.

Common sizes for ERW Steel Pipe range from 2 3/8 inch OD to 24 inch OD in a variety of lengths to over 100 feet. Surface finishes are available in bare and coated formats and processing can be handled on site to customer specifications.

Electric Resistance Welded steel pipe is available in new Prime and Secondary grades as well as used and surplus (availability depending on current stock).
