Stepped Coupling
The Teekay Stepped coupling is a “problem-solver” on any site with the ability to join pipes of different ODs and different materials. Typical applications:
- refurbishments (where the contractor is connecting a piping system back into the original layout)
- repairs to old water mains (where the pipe is so corroded it needs to be replaced with a new material in metric size)
- chamber connections
- pipe material transitions
- joining metallic pipe to plastic pipe
