Follow us

We provide Weld End Couplings from 3” nb to 48” nb rated up to ANSI 900, suitable for water, oil, gas, steam and other pipelines. Available in API 5L / ASTM A106 or equivalent body material and ASTM A193 Gr. B7 Screw Bolts.

Key benefits of Mechanical End Couplings:

  • Can be easily installed without prepping the pipe ends.
  • The couplings are designed with radial and axial screw bolts allowing alignment of the two pipe ends together whilst compressing the sealing gasket to eliminate leaks.
  • Coupling can be permanently welded on-line.
  • Capable of withstanding axial forces when welded of when pipeline is axially supported.
  • Selection of sealing gaskets available.
