PolyEthylene Coupling And Transition
Crimp – Service pipe sizes for on-site assembly.
PECAT – Mains pipe sizes, factory assembled with PE pipe stub.
This is the UK Gas Industry Standard for Self Anchoring Mechanical Fittings for Polyethylene Pipe for Natural Gas and Suitable Manufactured Gas
This means that the joint is stronger than the PE pipe when an axial load is applied which tries to separate the parts. In simple terms the PE pipe will break before the mechanical joint will let go of the pipe
The SDR rating is the “Standard Dimensional Ratio” and refers to the geometry of the pipe and is a method of rating a pipe’s durability against pressure. SDR is defined as the ratio of the nominal outside diameter to the nominal wall thickness.
Maximum Operating Pressure is dependent on PE diameter, PE type and SDR rating. Please refer to GIS/PL2-2:2016 Table B1 for details
Our Kitemark certificates can be found and downloaded at the bottom of each product page on our website
The WASK PECATAdaptor has an extended body in comparison to a standard Maxidaptor which allows for more contraction of the PE pipe once buried after welding
Under normal circumstances you would transition from PE to steel outside a building. However, the WASK PECAT below ground entries / garage entries / Gover Risers allow the PE to come out of the ground whilst protected by a steel oversleeve and have a fire resistant connection within the PECAT joint
The use on WASK fittings of tooling not made by WASK will again invalidate any guarantee. WASK has not authorised nor has assisted any other manufacturer to make spare parts for its gas fittings or tooling range. WASK will be automatically exonerated from any liability resulting from the use of unauthorized competitors tooling on WASK crimp fittings.
Up to 2”/63mm male/female threaded connections are allowed. Above this size, plain ends are available for welding or split-flange fixings are available with WASK Factory Entry elbows.
All WASK PECAT, Crimp, Flexgrip and PE Compression fittings have full end load retention. This is with the exception of the PECATAdaptor which uses a Maxifit joint which may require additional restraint.
If it is 90mm and below then our BGE are electrically insulated as the internal Steel pipe is isolated by the outer PE Sleeve.
