Dear Mr.Pradip ,

GRP pipes are laminated using supplier's fiber mat and resin .After drying of the laminated joint we can check the Barcol Hardness using a tester normally available with the lamination team .Acceptable harness value varies with pressure rating of pipe and are mentioned in pipe supplier's manual .They also specify the widht of lamination ,number of layers of fiber mat to be used and curing time .

You could get all these details form web site of Amiantit ( AFIL) ,Future pipe .

Regards,

S.Muthukrishnan

Refer to ISO 14692 - 4 which provide details of installation and testing. 

Generally Hydro-test is the only test will provide the validation. 

There are other quality control requirement are mentioned in ISO to achieve final results (successful Hydro).

Be careful...requirement are too detailed and I am not sure abut the context in which this question has been raised.

Dear Mr.Pradip,

 

The existing and widely used GRP code is ISO 14692 Part 1 to 4 where it states fully about pre qualifications to testing’s and dispatch.

 

And GRE/ GRP / GRV are being welcomed by many big oil companies nowadays…

 

Cheers

Dear Nandesh Kumar,

After drying of the laminated joint we can check the Barcol Test with a Hardness tester .Acceptable hardness value varies with pressure rating of pipe and  mentioned in pipe supplier's manual (normally 35 bph)

 .They also specify the widht of lamination ,number of layers of fiber mat to be used and curing time.
