ASTM A333 Grade 1

ASTM A333 grade 1 is constructed from carbon-based alloy for low temperature service. The chemical composition of the A333 carbon steel pipe includes – manganese, phosphorus and sulphur. The tensile strength and yield strength for the A333 gr b pipe is variable among its grades. For example, the tensile strength is 380 MPa and yield strength is 205 MPa for grade 1. The tensile strength is 450 MPa and yield strength is 240 MPa for grade 3. While the tensile strength is 415 MPa and yield strength is 240 MPa for ASTM A333 grade 1 pipe schedule. The pipes made from SA333 gr 1 material are meant for low temperature applications. The A333 grade 1 pipe is available in either welded, ERW, CDW, fabricated or seamless type. While producing welded pipes, it is not necessary to add filler metals during the operation. These carbon steel A333 grade 1 pipes are surface treated. The pipe ends of the A333 Gr 1 seamless pipe could be bevelled, plain ended or threaded, depending on the requirement of the buyer.

Some of the surface treatments include a coating or finishing by Oil-dip, Phosphating, Varnish, Passivation or Shot Blasting. They could also be anodized or finished polish. The treatment gives the surface of the A333 gr 1 smls pipe a smooth and flawless appearance. ASTM A333 grade 1 pipe can be conventionally formed, cold-worked and welded. The A333 grade 1 pipe can be hot worked, but they can’t be hot worked below 1500 degrees F. The ASTM A333 grade 1 pipe equivalent pipe is used in the transportation of Chemical, Water and Gas.  SA333 gr1 pipe finds application in building or construction work, where they are used to deliver concrete pumps. We are one of the oldest A333 grade 1 pipe manufacturer.
