Maximum velocity natural gas pipeline tap
Maximum velocity natural gas pipeline tap
(OP)
What is the maximum velocity that should be used to determine the diameter of a tap on a natural gas pipeline. We use 60 ft/sec as maximum velocity for the pipeline itself, Is there a diffrentet condition for the tap itself?
Thank you
Thank you

If you can then its better to have a larger tee and then reduce down for the valve and main run.
Its stronger and you have less velocity related issues.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

My case is as following
I have an existing 2" tap where the gas consumption will increase in the near future
Minimum main pipeline operating pressure: 476 psig
Excepted Natural Gas pick consumption: 395 MCFH
Tap diameter: 1.437"
Pipe diameter after de tap 2” Sch 80
Length of the pipe: 18 meters
Velocity: 293 ft/sec (doesn't consider compressibility factor)
After the 18 meters the pipe changes to 3”
What methods can I use to predict the pressure drop through the tap itself? (I haver the one for the 2" pipe already)
How can I predict noise and vibration and evaluate if it can harm the pipeline?
Because of excessive regulation, my firm wants to avoid the change, I believe this can be a problem but I have no evidence to show. The transmission company hasn’t said anything about it.
Any additional information will be appreciated
