  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 plastics system. The metal part is generally Ni- plated brass. |
 |
 SOCKET FUSION : |
Socket welding is an established method commonly used to connect tap water system 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 surface. This type of welding can be carried out with in expensive equipments.. Tight joints can last lifetimes if jointing is carried out according to good 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. |
