  Threaded joints probably represent the oldest method of joining piping systems. Like Socket Weld fittings, threaded fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller.

  The dimensional standards for taper pipe threads are given in ASME B1.20.1. That document gives all required dimensions including number of threads per inch, pitch diameter, and normal engagement lengths for all pipe diameters.

  Threaded piping is commonly used in low-cost, noncritical applications such as domestic water, fire protection, and industrial cooling water systems.

  Threaded flanges are normally made of cast gray or malleable iron, cast brass or bronze, or forged alloy and carbon steel.

  They are available in three pressure ratings: Class 2000, 3000 and 6000.

  Hebei shengtian pipe-fitting group Co., ltd is specialized in manufacturing and exporting steel flanges and carbon steel pipe fitting. In additation to the standard products mentioned above, we are also able to make non-standard, special-designed items according to customers’ requirement.
