Description

Bare Uncoated LSAW Pipe for General Construction and Piling

Specifications

Bare LSAW (Longitudinal Submerged Arc Welded) pipe is a steel pipe manufactured through the JCOE or UOE forming process that has no external or internal protective coating. These pipes are characterized by a single, straight longitudinal weld seam and are primarily used for high-pressure, large-diameter applications such as oil and gas transmission, water pipelines, and structural construction where the end-user may apply custom coatings later.
