Specifications

Typical Applications

Typical orders for this 20# 3 inch Sch 40 pipe cover process water and cooling circuits, compressed air and steam distribution, boiler feed lines and general fabrication. Grade 20# is a low-carbon pipe steel with good ductility and weldability, so it bends, threads and welds predictably in the workshop and is often specified where a lower carbon content than Q235B is preferred. Pipe is supplied in fixed or random lengths with the end finish, surface protection and marking matched to the project specification.
