ST/ST 150LB FITTINGS

150lb stainless steel fittings are low-pressure components typically manufactured from Grade 316 stainless steel for high corrosion resistance. They are available in both threaded (NPT or BSP) and socket weld configurations, designed for applications with a maximum working pressure of around 300 PSI (20 bar). 

Key Specifications

  • Material: Primarily made from ASTM A351 ACI Grade CF8M (equivalent to 316 stainless steel) to provide excellent resistance to a wide range of corrosive environments.
  • Pressure Rating: Rated for a nominal pressure of 150lb (Class 150), with a maximum working pressure of up to 300 psi (20 bar). Some full sockets may be rated higher, up to 40 bar / 600 psi.
  • Standards: Dimensions and pressure ratings generally conform to standards such as ISO 4144 for threaded fittings and ASME B16.11 for socket weld fittings.
  • Applications: Suitable for use in marine environments, chemical dosing systems, water treatment, and food/beverage production where durability and cleanliness are important.
