PLIDCO® Weld+Ends is a safety-welding coupling that enables pipes to be joined without special preparation of pipe ends. Coupling allows pipelines to resume operation immediately at recommended pressures, keeping downtime to a minimum. Standard couplings have a single row of clamping and thrust screws at each end. It is operational when screws are tightened or it can be welded. Standard sizes range in API pipe sizes from 1-1/2" through 48" and at working pressures to 2000 PSI. Pipe Line Development Co.
