Hello,

I need some help regarding stress Analysis for Plastic Piping.

One of our customer is using Polybutene (PB) pipework which is currently having leaks. They have used Metallic T- connection for branches.

I have been requested to do a stress Analysis on this Plastic Piping having this metallic Tee connection.
Could someone as to what material would need to be considered for my Analysis . Is it FRP/ GRP (Material No: 20) ?
The reason I ask is because plastic pipe is a bit from FRP/GRP.

And I was looking at using the code ISO 14692. Is this a correct approach?
