PLIDCO Shear+Plug solves refining, pipeline, and chemical high-pressure / high-temperature line plugging problems - and is now available from The Pipe Line Development Company's new division, Cleveland Ohio.
Impervious to flow rate, the double-acting hydraulic cylinder and fitting (less than 1 in. to 8 in. for API nominal steel pipe) provides a positive metal-to-metal seal, complete with sealant backup that isolates sections of high pressure, high temperature, or otherwise hazardous piping for any length of time.
ANSI Class 900 or 2,200-psi Shear+Plug works the shear through, positions the sealing blind plate, and retracts it. No shell cutter is used to enter the pipe. The complete one-piece coupon is pushed into the receptacle housing for easy, complete retrieval.
