ASTM A53 Grade B Sch 80 pipe is a high-strength, thick-walled steel pipe produced in accordance with the ASTM A53 standard. It is commonly used for conveying fluids, gases, and industrial pressure systems, and is also widely used in structural engineering. The ASTM A53 standard covers seamless and welded steel pipes, of which Grade B has higher tensile strength and yield strength, and is suitable for scenarios that need to withstand greater pressure and stress. Grade B has a minimum tensile strength of 415 MPa and a minimum yield strength of 240 MPa, which is better than Grade A. Sch 80 means that the wall thickness of the pipe is thicker, and the wall thickness value varies with the pipe diameter. For example, the wall thickness of a 1-inch pipe is 3.73 mm, and the wall thickness of a 2-inch pipe is 5.54 mm. This thicker wall thickness enables the pipe to withstand higher working pressures.
