Dear dickdobson,
We are trying to replace ss316 Fire water pipes with GRE pipes. We are having information that it complies with only IMO level 3 where fire endurance test has been conducted for 30 minutes as I understand. Is any type of GRE material available with 2 hrs Firw rating.
In one of the ammenity centre pipe 316L is leaking which is given for firefighting purpose.Can somebody suggest some material or other way like filling that portion with fresh water. Underground pipe is of GRP.Firewater pump discharge is of Duplex Stainless steel
Thanks
SA
