ASTM A53 Gr.B Seamless Pipe
GNEE is one of the pioneers in providing ASTM A53 B carbon steel pipes, you can choose the right pipes and get the evaluation you want at the best price.
A53 Grade B seamless pipe is a general purpose pipe made by cold drawing process. A53 B steel pipe has high strength characteristics compared to Grade A. The minimum tensile strength of Grade B is 415 MPa and the minimum yield strength is 240 MPa. And the manganese and carbon content in the composition is also higher at 1.2% and 0.30%.
A53 Grade B seamless pipes can also be provided with different finishes such as black, hot dip galvanized, anti-corrosion paint to improve corrosion resistance. Ensure the service life of A53 Gr.B high temperature pipes in high temperature corrosive environments such as low and medium pressure boilers, shipbuilding, fluid transportation, power plants and chemical plants industrial piping systems.
