We have a GRE fire fighting ring that experienced leaking at different joints, its 12-inch, working pressure 12 bar

we will assign a contractor to repair, but I need some knowledge in, methods of repair, the main cause of failure

Also if there is a company in the middle east that specialize in this field

Many parts of the middle east are seismically active. This could easily be the root of your problem or a red herring.

"GRE (Glass Reinforced Epoxy) / GRP (Glass Reinforced Plastic) / FRP (Fiberglass Reinforced Plastic) Pipes have high mechanical strength; however the material tends to be brittle and will weaken under strong impact. Leak will start to occur when the GRE/GRP/FRP piping system is subjected to heavy vibrations."
