Mechanical Repair Couplings
TDW Mechanical Repair Couplings are used to temporarily or permanently connect two sections of power, petrochemical, and oil and gas pipelines. These couplings can be used to connect pipe ends without special end preparation, and product flow can be initiated immediately after installation of the couplings.
Couplings may be anchored or unanchored. An anchored coupling has been either clamped or welded to the pipeline. An unanchored coupling is installed without clamping or welding. With unanchored couplings, lower pipeline pressures may be required. A coupling used as a temporary connection (and not welded in place) may be reused as long as its seals are replaced.
