HIGH IMPACT STUB ENDS
High Impact Pipe stub ends are the key to the integration of plastics with steel pipe systems. The High Impact Pipe stub end is a cast SG iron pipe fitting which is available as a standard “Victaulic” stub end. The coupling is zinc coated to provide additional protection against corrosion. High Impact Pipe stub ends are supplied factory fitted to the pipe. The concept of immediate installation of pipe using cast iron ends without welding is unique to High Impact Pipe and is achieved by a mechanical interference bond between the cast iron stub end and uPVC pipe. Serrated teeth on the inner surface of the stub end bond firmly to the pipe and provide a watertight seal. Pipes and fittings are then coupled using the standard mining cast iron clamp. The pipe system is ready for immediate operation.
