ANSI Class 150 Slip-on Flange

ASME’s flange standard ASME B16.5 specifies dimensions, pressure classes, materials, tolerances and testing for ½–24 inch pipe flanges/fittings. For sizes over 24 inches, ASME B16.47 (divided into Series A/B for diverse design needs) applies.

ASME 150# slip-on flanges are commonly fabricated from carbon steel, stainless steel, or bronze, balancing strength, toughness, and cost. ANSI class 150 flange’s design allows for straightforward installation via welding and bolting, ensuring a reliable, leak-tight seal in medium-pressure and temperature services. These slip-on flanges are widely applied in critical industries including oil and gas, water treatment, and heavy manufacturing. The specific material selection determines their suitability for different fluids and operating environments within pipeline systems.
