About PE-RT II Butt Fusion Reducing Tee
PE-RT II butt fusion reducing tee creates a 90-degree branch from a larger main PE-RT II pipeline to a smaller branch size. It combines branching and size reduction in one fitting while maintaining welded connections on all three ends.
This fitting is used where a smaller secondary line must be taken from a larger heating, hot-water or compatible thermal-fluid main. When ordering, the main pipe size and branch size should be specified together, for example 160 × 110 mm.
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.
Product Details
Overview
The PE-RT II butt fusion reducing tee forms a branch connection where the branch outlet is smaller than the main run. It allows a size transition at the branch while maintaining a welded PE-RT II piping connection.
Product Features
- PE-RT II construction
- Butt fusion jointing
- 90-degree reducing branch configuration
- Wide range of main-size and branch-size combinations
- Suitable for compatible PE-RT II piping systems
Applications & Installation
Typical Applications
Used in compatible PE-RT II systems where a smaller branch connection is required from a larger main pipeline, including heating distribution, hot-water circulation and other compatible thermal-fluid piping applications.
Butt Fusion Jointing
Prepare, face and align the pipe and fitting ends, then perform butt fusion using compatible welding equipment and the applicable project installation procedure.
