We present the new Weld+Ends coupling developed by our representative PLIDCO, a safe and quick way to connect pipes containing crude oil, gasoline, LNG, jet fuel, asphalt, steam, chemical process and other products so that flow can be resumed immediately.
No special preparation of pipe ends is required. Cut the pipe and slide on the PLIDCO Weld+Ends coupling. With clamping and thrust screws fully torqued the pipe is joined and leakproof seals are engaged.
PLIDCO Weld+Ends coupling can be left with screws torqued only or they can be welded depending on the MAOP of the pipe nNot anchored or pipe anchored rating that needs to be achieved. Refer to the chart in the installation instructions for recommended anchored and Unanchored pressures as well as welding instructions. If welding is required the pipeline can be under pressure.
With PLIDCO's new Weld+Ends coupling's weld-friendly set screw option, traditional low-carbon set screws have been replaced with commercially available screws tightened with a hex or Allen wrench. Factory testing has shown their strength to be equal to or greater than that of a traditional set screw.
This is a technical engineering improvement for PLIDCO's Weld+Ends coupling. A low-carbon weld plug has been added to the back of the set screw. The plug has a smooth, rounded surface for easy welding, and its steel material matches the coupling body. Tests have demonstrated its effectiveness.
