GRP Double Socket Couplings provide an engineered flexible joint that matches the structural longevity and corrosion resistance of the GRP pipeline itself. The coupling collar is manufactured from high-density filament-wound fiberglass roving impregnated with vinyl ester or isophthalic resin, delivering massive circumferential burst resistance.\n\nInside the coupling collar, dual circumferential grooves house heavy EPDM elastomeric sealing gaskets manufactured to EN 681-1. Each gasket features multi-lip sealing geometry that energizes under internal hydrostatic pressure: the higher the internal pressure, the tighter the rubber lips press against the smooth machined spigot ends of the pipes. A central elastomeric rubber stop ring prevents pipe-to-pipe contact during installation and provides an expansion gap for longitudinal thermal movement.\n\nThe coupling allows up to 1.5 to 3.0 degrees of angular deflection (depending on diameter), enabling pipeline contractors in Iraq to lay long pipelines along highway curves without installing expensive fabricated bends.

GRP Double Socket Couplings provide an engineered flexible joint that matches the structural longevity and corrosion resistance of the GRP pipeline itself. The coupling collar is manufactured from high-density filament-wound fiberglass roving impregnated with vinyl ester or isophthalic resin, delivering massive circumferential burst resistance.\n\nInside the coupling collar, dual circumferential grooves house heavy EPDM elastomeric sealing gaskets manufactured to EN 681-1. Each gasket features multi-lip sealing geometry that energizes under internal hydrostatic pressure: the higher the internal pressure, the tighter the rubber lips press against the smooth machined spigot ends of the pipes. A central elastomeric rubber stop ring prevents pipe-to-pipe contact during installation and provides an expansion gap for longitudinal thermal movement.\n\nThe coupling allows up to 1.5 to 3.0 degrees of angular deflection (depending on diameter), enabling pipeline contractors in Iraq to lay long pipelines along highway curves without installing expensive fabricated bends.
