FRP 3" 3000# Pipe need to connect ANSI 4" 300# RF Main Line!

FRP 3" 3000# Pipe need to connect ANSI 4" 300# RF Main Line!

FRP 3" 3000# Pipe need to connect ANSI 4" 300# RF Main Line!

(OP)
I have a situation, where I need to connect a Fiberglass 3" 3000# from a Well Head Christmas Tree to Existing 4" 300 RF Flowine which is also obviously coming from another well!

I have no Idea how to couple 3" 3000# Line to 4" 300# Line.

I never worked in FRP pipelines before,

So there is also another question is 3" 3000# FRP flange is RF or RTJ?

Can anyone help me out, here!!!

Thanks in Advance!!!

RE: FRP 3" 3000# Pipe need to connect ANSI 4" 300# RF Main Line!

You are truly overthinking this. Add a 3" API 3000 flange to the FRP. Build a spool with a steel 3" API 3000 flange on one end, weld a 4X3 concentric reducer to it, finally weld a 4" ANSI 300 flange on the other end. It really is that easy. If the bolts are too hard to get to, add a 3 ft pup to either end (the 3"inch might be a few dollars cheaper, but hydraulically it doesn't matter).
