The seamless pipes range in outer diameter from 17mm to 914mm, the LSAW pipes range from 18 inches to 56 inches. The wall thickness of the pipes ranges from 2mm to 60mm and the schedules range from sch10 through XXS. The length of the ASTM A691 Pipe products ranges from single random to double random and custom sizes. The pipes can also have different ends such as the plain end, beveled end, protect by plastic caps on both sides and other types as well. The ASME SA691 EFW Pipe is welded through a procedure called the electric fusion weld. A high temperature electric arc is used to weld the pipes together from strips or sheets of pressure vessel quality grades of materials. Please feel free to contact us for more information on the ASTM A691 Material and pricing.
