About PE-RT II Butt Fusion End Cap
PE-RT II butt fusion end cap is used to terminate and permanently close the end of a compatible PE-RT II pipeline. After butt fusion, the cap becomes part of the welded piping system and provides a closed pipeline end.
It can be used at final pipeline ends, reserved extensions or other locations where a PE-RT II line must be sealed. The cap size should match the outside diameter of the pipe being closed.
About PE-RT II Material
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.
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.
Operating Temperature
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 70–80°C range, while short-term or maximum design conditions can reach about 95°C. Final temperature and pressure limits should always be confirmed against the actual pipe specification and project design conditions.
Typical Applications
- Secondary district-heating and heat-distribution networks
- Building heating and hot-water circulation systems
- Radiant heating and underfloor heating systems
- HVAC hydronic heating and cooling circuits
- Heat-pump and geothermal circulation systems
- Compatible industrial hot-water and thermal-fluid pipelines
- Other hot- and cold-water piping applications requiring a corrosion-resistant welded plastic system
Selection Considerations
For project selection, the required pipe outside diameter, SDR or wall thickness, design pressure, normal operating temperature, maximum temperature, fluid medium and installation method should be confirmed together. This is especially important for heating networks because allowable pressure changes with operating temperature and intended service life.
