Product Overview

The PE100 Electrofusion Reducing Coupler is the industry-leading solution for creating a secure, in-line transition between two polyethylene pipes of different diameters. Essential for network expansions, repairs, or designs requiring a change in pipe size, this fitting guarantees a flawless connection. Each reducer features a barcode that contains the precise welding parameters for its specific size combination. When scanned by an electrofusion processor, this code initiates a fully automated and controlled fusion cycle. This intelligent process creates a homogenous, monolithic joint that is stronger than the pipes it connects, providing a permanent, leak-proof seal and a digital weld record for full project traceability.

Key Features

Automated & Traceable Welding: The barcode system removes installation guesswork, ensuring every transition is welded according to precise scientific parameters. The digital weld log supports quality control and long-term asset management.
Seamless In-line Transition: The concentric reducer design enables a smooth and gradual diameter change, minimizing flow turbulence and pressure loss for optimal hydraulic performance.
Ultimate Joint Reliability: The electrofusion weld becomes an integral part of the pipeline, delivering a permanent, leak-proof joint and eliminating risks associated with mechanical couplings.
Full Standards Compliance: Manufactured in strict accordance with GB/T 13663.3-2018 for PE water supply systems and designed with DIN compatible dimensions for global project integration.
Premium PE100 Material: Produced from 100% virgin PE100 resin, offering excellent resistance to chemical corrosion, abrasion, and environmental stress cracking for a service life exceeding 50 years.

Available Types / Connection Methods

We provide one of the most extensive electrofusion reducer size ranges available, ensuring compatibility with a wide variety of pipeline design requirements.

SDR11 (PN16): A comprehensive range covering sizes from small service connections such as 32×25mm up to large main line transitions like 500×400mm for high-pressure systems.
SDR17 (PN10): Designed for large-diameter transmission pipelines and lower-pressure distribution networks.

Applications

Pipeline tapering applications where pipe diameter is gradually reduced as distribution demand decreases.
System upgrades and pipeline repairs connecting new, larger-capacity pipes with existing smaller infrastructure.
Pump, valve, and equipment connections where pipe diameters must match equipment inlet or outlet sizes.
Integration with PE-to-metal transition fittings when connecting to legacy piping systems of different diameters.

Standards & Quality

Manufactured in an ISO 9001 certified facility using premium PE100 raw materials, ensuring consistent product quality and compliance with international pipeline standards.
