FRP pipe materials vendor do not have any information unless they are the manufacturers. I came across that even the person who you are dealing within the manufacturer side is very important to be able to get the right information.

I have experienced that the manufacturing and design code is very important for the purchasing FRP pipes. Some of major manufacturers do not have the required testing and the reliable information on material in terms of the design code, and they use the manufacturing code information only. So this is the one (based on the test pressure)that you normally can obtain. This puts the stress engineer under pressure and it is also difficult to explain this others after having the shelf material. They may even accuse you that you do not have proper knowledge in the analysis.

So I suggest you to read the design and manufacturing code together and insist to obtain the right information related to the FRP material you need to use.

I wish you good luck, and please share with us your findings.
