Suitability

Suitable for pipeline pigging operations, due to the smooth bore.

Concept of EasiSlim

The EasiSlim flange has been designed not only for improving the ease of connections, but also with maximising flow capability in mind. PE flange adapters with the slim design, feature a steel reinforced ring buried within the flange face, which means a significantly smaller backing ring than a traditional flange. This eliminates the need to upsize other valves or components and is easy to install due to the rotatable functionality of the backing ring.

EasiSlim has a smaller backing ring configuration but retains a full size-for-size bore.

The Advanced Flange Interface

The Advanced Flange Interface features a superior design, where by the steel backing ring and the steel reinforcement ring work together to provide maximum support to the flange face, for a secure connection.

The EasiSlim flange provides a high quality secure connection between the PE pipeline and metallic component, which delivers long term joint integrity, critical to the longevity of the pipeline.

355mm EasiSlim Flange connects 355mm OD (outside diameter) PE pipe directly to a 300mm DN PN16 valve. A traditional 355mm PE Flange requires a 355mm ID (internal diameter) PN16 valve for bolting to match.

Most size for size Flanges, temporarily reduce the bore size which can reduce joint strength and cause blockages - EasiSlim avoids all these problems by maintaining full flow.

Extensive performance tests conducted to meet the most up to date approval requirements.

Extreme Tensile Testing

Extensive performance tests were conducted in a dedicated high specification engineering facility to meet the most up to date approval requirements . The EasiSlim is proven to withstand loads exceeding 100 tonnes, ensuring durability in demanding installation scenarios. 

Industry-leading tests, including hydrostatic testing and butt fusion quality tests, ensure EasiSlim's strength, surpassing even that of traditional pipes under immense pressure.
