A53 GR. B Carbon Steel Seamless Pipes

 

ASTM A53 pipe (also referred to as ASME SA53 pipe) is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and air lines. It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging, subject to certain qualifications.
 

This specification covers seamless carbon steel pipe for high-temperature service

Sizes (Seamless): 1/2" NB - 60" NB

Sizes (ERW): 1/2" NB - 24" NB
