Threaded Fittings is screw connected steel pipe fittings, it is a kind of high pressure forged fittings. Kaysuns provide threaded fittings with NPT, ISO, BSP pipe thread in stainless steel, duplex steel, alloy steel etc.

Introduction of Pipe Thread:

There are currently three types of pipe thread for piping works:

  1. Tooth profile angle is 55°, taper 1: 16, internal thread type: Rp, Rc, outer thread is R. The thread of Rp-R is widely used in construction engineering.
  2. ISO228 is non-threaded sealed pipe thread. It's parallel for the internal and outer thread. The tooth profile angle is 55°.
  3. ANSI 1.20.1 is thread sealed pipe thread. The tooth profile angel is 60°, internal and outer thread are taper 1:16. It is used widely in high pressure fittings and high temperature fittings. Threaded fittings in ASME B16.11 is NPT thread.
