3" sch 40 A333 Gr. 6 pipe
3" sch 40 A333 Gr. 6 pipe
(OP)
I have an existing 3" sch40 A333 Gr.6 pipe which is located aboveground but it is used as a part of pipeline. Currently the design pressure of this line is 1440 psig. We need to increase this design pressure to 2250 psig. The flange will be changed out with 1500# flange.We will re-pressure test the existing piping to 2250 psig x 1.5.
The pipe is used for sweet dry fuel gas. Is there any problem to do this? Can somebody give some comments on this? Thanks.

Our existing pipeline is built to CSA Z662.
