What is ASTM A53 Carbon Steel Grade B Pipes ?

ASME SA 53 Carbon Steel Grade B Pipes is a carbon steel alloy, used as structural steel or for low-pressure plumbing. The alloy specifications are set by ASTM International, in specification ASTM A53/A53M.

A53 pipe comes in three types and two grades, A53 Type F, which is longitudinally furnace butt welded or continuous welded, A53 Type E, which is longitudinally electric resistance welded, and A53 Type S, which is seamless pipe, produced by hot working, and possibly cold finishing, the steel. 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.

ASTM A53 Grade B Seamless Pressure Pipe (also known as ASME SA53 Grade B Pipe) are seamless carbon steel pipes used for high tempertaure applications (up to 750 degrees F) in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.

ASTM A53 Carbon Steel Grade B Pipe Hardness :

Brinell hardness is the most widely used methods in carbon steel pipe hardness testing . This method uses the earliest, due to its imprint, and thus the hardness values ​​affected by the sample organization microsegregation ingredients uneven minimal impact, test results points sprinkle a small degree, good reproducibility, can objectively reflect the objective hardness of the material.
