RE: FRP Pipe Butt Join
Alternatively ask the pipe manufcaturer. I used to manufacture filament wound pipes and we gave out this information to the installers.
RE: FRP Pipe Butt Join
Had a hard time getting copy of standard. Client supply of old pipe, manufacture has since gone out of business. Resolved issue by engaging local contractor who specified joint method, with subsequent hydro.
Once again thanks for your information.

1. The weld thickness at least that of hand layup pipe and 25% thicker than filament wound for the same diameter.
2. For 150 psi rated pipe the width should be the larger of 8" or the nominal diameter (i.e. 12" weld 12" wide, 4" weld 8" wide) Alternatively you can calculate the width based on a minimum 100 psi shear stress between half of the weld and the pipe.
