Hi All
Please refer to subject regarding the GRP/GRE/HDP piping materiel, can NFP code allow to use these material for cooling water in refinery and gas plants. anyone have experience please share.
Best Regards
SJones,
all information in this page is related with material and use, but no information for refinery cooling water service use. I need if NFPA allow or not.
Best regards
I looked but no specific information founded. NFPA suggests for protection but not for like my question (material selection). we have old system and need to replace it. project is under discussion but no relevant codes & standards found which can support us or reject us for the use of GRP/GRE above ground.

Company want to replace existing cooling water service piping in refinery due to aging and corrosion related issues. project is still in discussion stage. these pipes are running on pipe racks. My question was, does NFPA code allow to change carbon steel piping with GRP /GRE/FRP piping or not.
In-addition I have not see GRP pipes in cooling water services yet.
Best Regards
GRE pipes have been extensively used in the Middle-East for chilled water & fire water applications. As long as the bonding procedure specification is adhered to, you get excellent results.
Do remember these pipes are may be 10 times costlier than CS. So, economics also play a part. CS piping + water treatment is also one option that you might explore.
I know and have experience for GRE for fire water services but my question is does we can use for cooling water services in refinery or in gas plant, does NFPA allow. please share your experience or reference or let me know if NFPA allow and which codes is.
Thanks
