End restraint couplings (MULTIGRIP)Repairing

There was a damage to the main water supply GRP pipe DN 1400. It was decided to replace the damaged section of the water supply system with an insert made of PE pipe DN 1200. At the same time it was necessary to provide reliable protection against the axial movement of the PE pipe when working under pressure. To solve this problem, two Reducing Couplings with an End-Restraint system for PE pipe were specially manufactured by Nova Siria. Installation and tests were successful.
