Re: Re: [MW:7150] RE: 7127] Material for Sea water piping for Offshore enveronment.

Hi ,

GRP pipe is best cost will be more. you can say lifelong service.
Don't go for Galvanized item it will not with stand for long run at
least two three years difficult. Cu Ni larger dia pipe is difficult and
more expensive.

For cheap and long run say 15 / 20 years , cs pipe IS 3589, internal
coating with Poly glass coating ,it is cheap and easily you can get it.

>Dear,

Plz go for GRP(Glass reinforced plastic) material.



Fibre Glass Reinforced Plastic Pipe is a matrix or composite of glass

fibre, polyeser resin and fillers. These pipes possess better strength

durability high tensile strength low density and are virtually

inert.Fibre Glass pressure pipes are intended to be manufactured in

diameters upto 2400mm and length upto 18m. These pipes are now being

taken up for manufacture in India. Standard specifications have been

farmed by the BIS and for further details of G.R.P. Pipes please refer

to IS 12709 :1989



Yours truely,



Vineet
