ASTM A691 Grade 1-1/4 CR Class 22 Pipe

Manufacturer of ASTM A691 Grade 2.1/4CR Seamless Pipe, ASTM A691 9CR Cl22 ERW Pipe

ASTM A691 Grade 1-1/4 CR Class 22 Pipe comes under the A691 specification. This specification covers alloy steel pipes and carbon steel pipes that are fusion welded with filler materials. The pipes can also be fabricated from pressure vessel quality sheets. The ASTM A691 Grade 2.1/4CR Seamless Pipe is deemed as suitable for high pressure and high temperature applications.

Buy ASTM A691 Pipe, ASME SA691 EFW Pipe, Check Dimension Chart of ASTM A691 Material

There are different classes to the material ranging from class 10 through class 50. The material could be heat treated. The welding of the pipes is done either manually or automatically. The ASTM A691 9CR Cl22 ERW Pipe has different grades such sa 5CR, 9CR, P5, P11 and each of the grades have specific chemical composition and a set of mechanical properties. The pipes are used in different industrial applications according to the characteristics of each grade such as the ASTM A691 5CR Welded Pipe.


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.
