Product Overview

The PE100 Electrofusion Coupling (Straight Coupler) is the cornerstone of modern polyethylene piping systems, designed to create a robust, homogenous joint between two pipes of the same diameter. It is the most reliable solution for pipeline construction, extension, and repair projects. Each coupler is embedded with a barcode containing precise fusion parameters. When scanned by an electrofusion unit, it initiates a fully automated welding process that melts the PE100 material of both the fitting and the pipe into a single seamless structure. The resulting joint becomes stronger than the pipe itself, guaranteeing a permanent, zero-leakage connection with a fully traceable digital record for superior quality assurance.

Key Features

Automated & Traceable Welding: The integrated barcode eliminates human error and ensures precise electrofusion parameters every time. Each weld produces a digital record for project verification and long-term asset management.
Superior Joint Strength: The electrofusion process forms a monolithic joint that is stronger than the pipe itself, offering excellent resistance to pull-out forces, pressure changes, and ground movement.
Broad Application Versatility: Available in SDR9, SDR11, and SDR17 pressure classes, making these couplers suitable for high-pressure gas distribution, municipal water networks, and large-diameter transmission systems.
Exceptional Durability: Manufactured from 100% virgin PE100 resin, providing outstanding resistance to chemical corrosion, abrasion, and environmental stress cracking for a service life exceeding 50 years.
Full Standards Compliance: Produced in accordance with international standards such as ISO 4427 and DIN 8074, ensuring compatibility and reliability for global infrastructure projects.

Available Types / Connection Methods

We provide a comprehensive range of electrofusion couplings (straight couplers) to meet various pipeline design requirements and pressure classes.

SDR9 (PN20): Sizes from DN110 to DN315, suitable for high-pressure gas distribution networks and demanding industrial applications.
SDR11 (PN16): The most widely used range, covering DN25 to DN630, commonly applied in municipal water and gas pipeline systems.
SDR17 (PN10): Sizes from DN315 to DN800, ideal for large-diameter transmission lines and lower-pressure water distribution networks.

For commonly used sizes such as DN90, DN110, and DN160, we also offer standard-grade product options to accommodate diverse project budgets without compromising safety or reliability.
