NGD Sliding Type Expansion Joints

The design complies with various international standards.

  • Stationary – EN8 or equivalent
  • Jointing ends – Steel
  • Slider – 304/316SS
  • Jacking bolts – 431SS
  • Seals – Quad-Rings
Expansion joints are utilised as a thermal compensator in air and water lines. The couplings are designed to connect to high pressure pipes in a vertical shaft column. Tru tapered pipe couplings are used for industrial, commercial, and institutional piping systems.
