Structure Construction ASTM Steel Pipe ASTM A53 Grade B Fixed /
Random Length
ASTM A53 pipe is sized according to the nominal pipe size (NPS)
system. It is commonly available with national pipe thread ends or
with plain cut ends. It can be used for steam, water, and air
conveyance. It is also weldable and can be used in structural
applications.
A53 Grade B Seamless is our most polar product under this
specification and A53 pipe is commonly dual certified to A106 B
Seamless pipe.
