Understanding Schedule 80 Steel Pipe
Schedule 80 steel pipes are thicker than standard pipes, which allows them to withstand higher pressures. The “schedule” refers to the wall thickness of the pipe; higher numbers indicate thicker walls. For instance, compared to Schedule 40 pipes, Schedule 80 pipes have a significantly greater wall thickness, making them suitable for more demanding applications.
Material Specifications
Typically, Schedule 80 pipes are made from carbon steel and conform to ASTM A53 and ASTM A106 standards. These specifications ensure the pipes are robust and suitable for various conditions, including high temperatures and corrosive environments. Additionally, Schedule 80 pipes can be used for welding, flanging, and bending, providing versatility in applications.
