LUNCH & LEARN with VINIDEX

Electrofusion jointing plays a critical role in the performance of PE pressure systems, particularly where consistency and long-term reliability are required. Our team recently had a session with Sam Sloan from Vinidex, who walked through this in more detail.

Rather than staying at a product level, the discussion centred on how jointing methods directly affect performance, compliance, and installation quality on site.

Polyethylene, particularly PE100, is commonly used across pressure systems due to its flexibility, strength, and ability to handle a wide range of operating conditions. The use of long pipe coils also reduces the number of joints required, which has clear implications for constructability and installation risk.

Electrofusion jointing was a key focus, highlighting how a controlled fusion process is used to create a consistent bond between pipe and fitting. Compared to mechanical connections, it removes a level of variability on site, which is often where issues begin.

Preparation and accreditation requirements were also covered in detail, including the removal of the oxidised surface layer using mechanical methods and the need for certified installers in line with industry standards.

We also looked at fitting performance and testing requirements, including pressure ratings and hydrostatic testing across both water and fire systems, as well as digital QA tools such as WorkFlow used to document and track electrofusion installations. This reinforces the importance of proper verification prior to commissioning.

These systems are rarely visible, but their performance depends entirely on how they’re designed, coordinated, and installed.
