Electrofusion PPR

The DN160 electrofusion PPR fitting is designed for medium-duty hot water pipelines, specifically for connecting to main district heating supply lines with large diameters. It is manufactured using high-performance base resins, such as Borouge's RA140E or PPB4228. The grey fitting is suitable for high-pressure hot water (≥20 bar) and features a uniquely thickened structure to resist softening under high temperatures. It is optimized for uniform heat distribution in large-diameter connections, making it ideal for large thermal power stations and factory hot water circuits. The excellent insulation properties of PPR help maximize heat energy retention. After passing rigorous pressure and long-term heat resistance tests, it provides a reliable, long-life solution for major heating projects.

The electrofusion process creates a homogeneous and perfect fusion interface, resulting in a joint strength that can exceed that of the pipe itself. These welded joints undergo stringent long-term testing, ensuring they can withstand the same working pressure and service life as the pipeline, eliminating leakage risks. Therefore, electrofusion PPR connections are particularly suited as the preferred interface system for high-quality potable water and heating systems.

Complete Fitting Designed for PPR – Uniform Composition
Thickened Design – High Pressure Rating and Long-Term Temperature Resistance
Precise Socket Depth and Fusion Zone Width – Reliable Welding

The key to choosing correctly between these two materials lies in defining the application scenario.

Choose PPR Fittings if your project involves:
- Building Interior Hot/Cold Water Pipes: This is the traditional strength of PPR, especially for residential, hotel, and hospital water supply systems.
- Heating Systems: Such as connections between underfloor heating loops and manifolds, where high-temperature resistance is needed.
- Limited Budget & Exposed Pipelines: PPR's rigidity is better for exposed installation, and fusion equipment costs are lower.

Choose PE Fittings (especially electrofusion series) if your project involves:
- Municipal Underground Water/Gas Mains: This is PE's primary domain, where its flexibility and reliable electrofusion connections suit complex underground environments.
- Large-Scale Outdoor Irrigation/Water Transfer Projects: Requiring long-distance laying and weather resistance, PE offers the best cost-effectiveness.
- Harsh Environments or Seismic Risk: PE pipeline systems offer superior deformation resistance and higher safety.
