Working pressure for schedule 40

The working pressure for Schedule 40 pipes varies based on the material and diameter of the pipe. For instance, Schedule 40 PVC pipes can typically handle pressures up to 280 psi for smaller diameters, while steel pipes may have different ratings based on their specific grades and wall thicknesses. It's essential to consult the manufacturer's specifications or relevant standards for accurate pressure ratings for the specific type and size of Schedule 40 pipe being used. Always consider factors such as temperature, fluid type, and safety margins when determining appropriate working pressures.
