Plasson Large Bore Couplers Electrofusion fittings for 450 OD – 1000 OD PE Pipe
PE10 0 HSC R RESI N
Product Geometry • Extra material at areas of maximum load • Thinner wall above fusion zone to enhance gap closing and weld quality • Customised profile at weld zones to improve weld quality • Long insertion depths allow longer cold zones to help prevent melt out
Insulating weld Straps • Prevent expansion during weld process • Shorten fusion time by reducing heat loss • Allows coupling to shrink during cooling - reduces stress on weld during cooling period • Does not require tightening or intervention from the operator • Will be loose after cooling • Can be removed after cooling - not a structural element of the finished weld
Dual Weld Zones • Can be welded simultaneously or in sequence • Allows flexibility with installation procedures
Rising Pin Weld Indicator • Located in the middle of strap buckles • Tapered design prevents melt out • Not an indicator of weld quality
Wires Embedded In Coupling • Prevents damage during assembly • Thick melt layer to help close large gaps • Ensures even heat transfer during welding • Oxygen free environment around the heating wire all the way up to gap closure • Internal machining after wire imbedding to control internal diameter and provide a smooth welding surface
