Alloy Steel Pipe Pressure Rating

Alloy steel pipe pressure rating indicates the maximum working pressure for welded alloy steel pipes at a temperature of 400°F. These ratings are based on the dimensions specified by ANSI B36.10 for outside pipe diameters and wall thicknesses.

• 1 in (inch) = 25.4 mm
• 1 psi (lb/in²) = 6,894.8 Pa (N/m²) = 6.895×10-² bar
