Quantity
The 150LB SO Flange is a high-performance pipe-connecting component manufactured in full compliance with ASME B16.5, the globally recognized standard for pipe flanges and fittings. Crafted from ASTM A182 F316L – a low-carbon molybdenum-bearing austenitic stainless steel – this 150LB Slip-On Flange delivers exceptional resistance to pitting, crevice corrosion, and chloride attack, making it particularly suitable for aggressive service environments including chemical processing, marine applications, and pharmaceutical lines.
Designed with a Raised Face (RF) sealing surface, the 150LB RF SO Flange ensures concentrated gasket compression, which significantly reduces the risk of leakage under both low and moderate pressure conditions. The Slip-On (SO) configuration allows for easy alignment and welding – the flange slips over the pipe end before being fillet-welded both inside and outside, providing strong mechanical strength while simplifying installation and reducing fabrication costs compared to weld-neck alternatives.
With a Class 150LB pressure rating and a 2-inch nominal size, this ASME B16.5 SO Flange is optimized for systems operating at up to 285 psi (for stainless steel at ambient temperature). Its robust construction and precision-machined bore ensure concentricity and smooth flow transition, minimizing turbulence and pressure drop in piping networks.
Key Applications
This 150LB Slip-On Flange is widely deployed across:
- Oil & gas refineries – for connecting low-pressure auxiliary lines, cooling water circuits, and fire-water systems.
- Chemical and petrochemical plants – handling corrosive fluids such as acids, alkalis, and organic solvents, where ASTM A182 F316L material excels.
- Water and wastewater treatment – including desalination units and high-purity water distribution.
- HVAC and power generation – for steam, condensate, and chilled water loops.
- General construction and shipbuilding – where reliable, cost-effective joining of dissimilar pipe materials is required.
