ASTM A106 SCH160 Threaded Nipples Carbon Steel Pipe Fittings

ASTM A106 SCH160 threaded nipples are carbon steel pipe fittings that have widely used range.There are two shapes for choose:TOE(threaded one end) and TBE (Threaded both ends).

Rated 4.6/5 based on 229 customer reviews

ASTM A106 SCH160 threaded nipples are always used in high pressure applications because the wall thickness is thicker than most of pipe nipples.ASTM A106 is the specification for seamless pipes in material of carbon steel.



Threaded One End(TOE):

One end is threaded and the other end is welded.

Threaded Both End(TBE):

The nipple is threaded at both ends


End Types:

Plain(PE); Beveled(BE); Threaded(THD)



  1. Shorten construction period and improve project quality.
  2. Reducing energy consumption is conducive to environmental protection.
  3. Reduce equipment investment and low additional cost.



oil refineries, chemical processing, petrochemical and many other industries. These pipe fittings can withstand high temperature and high pressure.
