About PE-RT II Electrofusion Stub End
PE-RT II electrofusion stub end is used to convert a welded PE-RT II pipeline into a detachable flanged connection. The electrofusion side is joined to the PE-RT II pipe, while the flange face works together with a compatible backing ring and mating flange.
This fitting is commonly selected where PE-RT II piping must connect to valves, pumps, meters, heat exchangers or other flanged equipment, especially where future disassembly or maintenance may be required. The stub end should match the pipe outside diameter and the required SDR / PN configuration.
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 benefits of a weldable plastic piping system.
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 pipe and fitting design, SDR or wall thickness, operating pressure and 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
Selection Considerations
For project selection, confirm pipe outside diameter, SDR or wall thickness, design pressure, normal operating temperature, maximum temperature, fluid medium, backing ring and mating flange requirements together.
Product Details
Overview
The PE-RT II electrofusion stub end provides a welded-to-flanged transition for compatible PE-RT II pipelines. It allows the plastic pipeline to connect to detachable bolted flange systems without changing the pipe material along the welded section.
Product Features
- PE-RT II construction
- Electrofusion jointing
- Flanged connection transition
- Used with compatible backing ring and mating flange
- Suitable for connection to valves, pumps and other flanged equipment
- SDR11 / PN16 and SDR17 / PN10 options as listed
Applications & Installation
Typical Applications
Used where compatible PE-RT II heating distribution, hot-water circulation, HVAC hydronic, heat-pump, geothermal or other thermal-fluid pipelines need a detachable flanged connection to equipment or another piping system.
Electrofusion Jointing
Prepare and clean the pipe end, scrape the fusion area as required, align and clamp the fitting, then carry out electrofusion using compatible welding equipment and the applicable project installation procedure. After the joint has cooled, assemble the compatible backing ring and mating flange according to the project requirements.
