Chemical Composition of GRV and GRE Pipe

Why bother? Let the supplier sign a statement that their pipe is and will be good for sea water transport and be done.

Do you know what is in your seawater? Be prepared, that question might come from the pipe supplier!

And then there is this information!

Glass Fiber Reinforced Polyester / Vinlyester Pipes produced by Inter Pipe Factory® are manufactured and tested according to international American Standards (ASTM / AWWA), European Standards (EN) and British Standards (BS)

AWWA STANDARDS
AWWA C950 is one of the most widespread product standards in existence for fiberglass pipe.

OH, no!!!!! It's you again!!!!!!!!!!!!

You may be too thick to understand this, but, there's a reason these people won't give you the composition.

First and foremost, I think you are incapable of understanding what the make-up of the material would mean!

Second, you don't NEED TO KNOW!!!!!!!!!!!

Get over your obsession with ASTM and ask the suppliers which is better. They are far smarter than you are.

Both questions you have asked are ridiculous, uninformed and a waste of everyone's time.

GO AWAY!

GRE/GRV pipe manufacturing is so nice to watch.

It is possible to use a materials compatibility chart to evaluate this prospect.

Thanks slack for the link. Actually I am new to GRE and GRV pipeline project.But, my company already completed 40 inch, 30 inch and 24 inch diameter underground seawater transportation pipeline for a refinery .Accepted material was GRE and GRV. This is new project and I have visited our pipe suppliers manufacturing unit and physically verified glass fibre, resin and internal liner.Composition is trade secret and GRE/GRP pipe material property will vary manufacturer to manufacturer.

Yes!!!! That's what everybody has been trying to tell you. You are WASTING your, and our, time by asking questions which are, for lack of a better word, useless, if not totally counterproductive.

You ARE WASTING TIME worrying about things over which you have no control and needlessly chasing ASTM specs looking for assembly instructions.

You are a waste of time and resources that could be put to productive use.

This is not a tutoring service, it is supposed to be for real engineers to discuss technical issues, not for people to solicit instructions on how to do their job.

The reason behind my question was simple. Just want to know, if there is any ASTM standard or EN standard or any other national standard which will provide the chemical composition details of the mentioned materials. Unfortunately in this specific case manufacturer is the only reliable source for information.

"my company already completed 40 inch, 30 inch and 24 inch diameter underground seawater transportation pipeline for a refinery .Accepted material was GRE and GRV."

Based on the above statement, why not research your company's old design and specification records. Past Experiences is a good source of information for learning purposes!

Generally for GRE/GRV/GRP construction, the pipe manufacturer has their own design data.Based on that pipeline and piping networks are designed.However, their specification (ie, design data book) provide only the details of mechanical properties and general composition (ie, resin, fiber and internal liner).That specification also contains mixing % of chemicals to join pipes.Hardening of the compound made from mixed chemicals will occur during curing time. Barcol hardness of the joint is the only NDT applicable for the acceptance of the joint . unfortunately, i couldn't find the chemical composition of liner, resin and the fiber used to strengthen the matrix.I think manufacturer is not interested to reveal the exact composition of the product.May be they have their own reason for that.

Of course! No manufacturer in their proper mindset will be willing to give up nor share those proprietary information! Those are trade secrets and are always secured, kept in a vault, specially if the subject products are patented!

Now for a really savvy, smart person like you, you can do the necessary analysis, and reverse-engineer the manufacturing processes... By doing so, You may even come up with a much better product than those that currently available?

Who is dreaming?

The OP must have been....
