About PE-RT II Electrofusion Reducing Tee
PE-RT II electrofusion reducing tee is used to create a 90-degree branch where the branch size is smaller than the main run. It is commonly selected when a PE-RT II main pipeline needs to connect to a smaller secondary line while keeping all three connections electrofusion welded.
The first and third dimensions represent the main run size, while the middle dimension represents the reduced branch size. For example, 160 × 110 × 160 mm means a 160 mm main run with a 110 mm branch. The fitting contains integrated electrofusion heating elements at its connection zones and should be selected to match the required pipe sizes and 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, branch diameter, SDR or wall thickness, design pressure, normal operating temperature, maximum temperature, fluid medium and installation method together. This is especially important for heating networks because allowable pressure changes with operating temperature and intended service life.
Product Details
Overview
The PE-RT II electrofusion reducing tee combines branching and size reduction in one fitting. It allows a smaller branch line to be taken from a larger main while keeping the main run the same diameter on both sides.
Product Features
- PE-RT II construction
- Electrofusion jointing
- Reduced 90-degree branch
- Main run remains the same diameter
- Wide range of branch combinations
- 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 mains need to feed a smaller branch line.
Electrofusion Jointing
Prepare and clean all three pipe ends, scrape the fusion areas as required, align and clamp the components, then carry out electrofusion using compatible welding equipment and the applicable project installation procedure. Allow the joint to cool before removing clamps or applying load.
