PE-RT II Butt Fusion Stub End<\/h1>\n

PE-RT II butt fusion stub end is used to create a flanged transition point in compatible PE-RT II piping systems. It is butt fused to the PE-RT II pipe and used with a compatible backing ring for connection to valves, pumps, equipment or other flanged components.<\/p>\n\n

About PE-RT II Butt Fusion Stub End<\/h2>\n

PE-RT II butt fusion stub end is used to convert a welded PE-RT II pipeline into a detachable flanged connection. The pipe side is joined by butt fusion, while the flange face works together with a compatible backing ring and mating flange.<\/p>\n

It is typically used when connecting PE-RT II piping to valves, pumps, heat exchangers, meters or other flanged equipment, and where future disassembly may be required. The backing ring, bolt pattern and mating flange specification should be confirmed for the project.<\/p>\n\n

About PE-RT II Material<\/h2>\n

PE-RT II (Polyethylene of Raised Temperature Resistance Type II) is a thermoplastic polyethylene material developed for piping systems that must maintain mechanical strength at elevated temperatures. Compared with conventional polyethylene, PE-RT II offers improved long-term temperature resistance while retaining the advantages of a weldable plastic piping material.<\/p>\n

Because PE-RT II remains thermoplastic, compatible pipes and fittings can be joined by butt fusion or electrofusion to create a continuous all-plastic welded pipeline system. The material is also valued for corrosion resistance, resistance to internal scaling, relatively low weight, smooth internal surfaces and installation flexibility.<\/p>\n

Operating Temperature<\/h3>\n

PE-RT II is used in hot- and cold-water and heating applications where elevated-temperature performance is required. The exact allowable temperature depends on the pipe and fitting design, SDR or wall thickness, operating pressure and the specified application class. Many PE-RT II piping systems are designed for long-term service in approximately the 70\u201380\u00b0C range, while short-term or maximum design conditions can reach about 95\u00b0C. Final temperature and pressure limits should always be confirmed against the actual pipe specification and project design conditions.<\/p>\n
