ASTM A53 Grade B Pipe




ASTM A53 Grade B Pipes is part of the ASTM A53 grade carbon steel material made pipes. There are different types and grades of the A53 standard that is used in low pressure plumping and other similar use cases. Steel India Co. is a manufacturer and supplier of these pipes in different scales, sizes and grades. There is ASTM A53 Grade B ERW Pipes which is electric resistant welded which makes it useful with welding applications to make the piping stronger and durable. Although the A 53 Gr B is the most used type in this grade, there are three different types, namely the Type F, Type E and the Type S. all three types of the A53grb pipes are for different purposes.

The Type E is different in that it is available only in the Grade A specification of the A53. There are different pressure classes such as the ASTM A53 Grade B Schedule 40 which are marked by the schedule number. The pipes range from NPS ½ to NPS 26 normally, which also correlate with the pressure classes and schedules. The ASTM A53 Type E is electric resistant welded in the longitudinal axis. The SA 53 Gr B can also have a butt welding or continuous welding in the form of the ASTM A53 Type F. The A53 Type S differs in that it is actually the ASTM A53 Grade B Seamless Pipes. We supply all types and please contact us for any inquiries.
