JOINTING TECHNIQUES
Mechanical Fittings: Semi mechanical fittings are injection moulded
with threaded metal inserts to allow for one part mechanical joining as
adapter between metal parts and/or other parts for socket-fusion jointing
to a plastic system. The metal part is generally Ni-plated brass.
Socket Fusion: Socket welding is an established method commonly
used to connect tap water systems using PP-R. The external surface of
the pipe and internal surface of the fitting are pre-heated and the pipe
is inserted in the fitting, creating a fusion joint between two surfaces.
This type of welding can be carried out with in expensive equipments.
Tight joints can last lifetime if jointing is carried out according to
goof working procedures.
Electro fusion: Although less popular than socket fusion, Electro
fusion fittings are also available in PP-R. The fusion is performed by
inserting the pipe into fitting and applying an electrical current. The
current heats the conductive thread, which melts the PP interface to form,
a fusion joint. Electro fusion is a safe and easy to control method.
Welding Compatibility: Tests have been carried out using butt-welding
and socket fusion techniques to evaluate the welding compatibility of
PP-R grades. The mechanical characteristics and pressure resistance of
the welded assemblies have proved comparable with un welded material.
