[MW:4277] RE: 4265] GRE pipes identification

Dear Rasheed,

GRE pipes are made by winding of glass mats/ rolls on moulds .etc….

As far as traceability is concerned thy do have the lot numbers traceable to resin/ glass wool batch numbers and certificates. Plus in addition to this as per code loi and other tests also are carried out on batches and recorded in test certificates.

Kindly ask for these………although the process is different than metal pipes but lot wise traceability ( with test certificates) is these for GRE pipes also.

 

Regards

Rajneesh
