Baker Coupling Products - Baker Dismantling Joint

The Baker Dismantling Joint is a double-flanged pipe fitting. Dismantling Joints allow for easy installation and continued maintenance of the fitting. Typical applications include pumping stations, water treatment works, sewage treatment works, plant rooms, meter chambers, power generation equipment and gas distribution stations. Baker Dismantling Joints can accommodate custom longitudinal adjustment dependent on the diameter and also allows for up to 2° of misalignment. Once adjusted the Dismantling joints movement can be restricted by using the supplied tie rods. The Dismantling Joints are designed such that the restraint system does not extend outside of the flange diameter. Baker Dismantling Joints can be easily installed with minimal special equipment needed. Dismantling Joints can be made starting an a nominal size of 2” and above, with common flange drillings to mate with AWWA C207 Class D, E, and F flanges with a working pressure of 150 PSI and higher. Specials can be made based on specific project requirements. Dismantling Joints are shipped with SBR gaskets, but can be changed based on different applications.

Material Specifications:
  1. Dismantling Joints shall be manufactured in the USA.
  2. Dismantling Joints shall meet or exceed provisions of ANSI/AWWA C219.
  3. Alternate materials and coatings can be provided as required by project specifications.
  4. All Stainless Steel 304/316 available.
  5. Designed so that no part of the restraint system extends beyond the flange diameter.
