Flange Type
Polyethylene pipes cannot be joint by any other method to other pipes made of non-PE materials (UPVC, asbestos, PP…). Wherever possible flange joints should be made before other joints are completed. The flange adaptor is butt welded to the pipe with the loose steel backing flange inserted inside, the use of bolts will be fitted to tighten the connection. This type of jointing is applicable where easy maintenance is required in the future.
