Hello all,
I have a situation where the mainline block valve in a 36" natural gas pipeline is closed for a period of time. During this time, the pressures on either side of the valve drift apart. e.g. Upstream pressure = 800psig. Downstream = 600psig. If the mainline valve is now opened what is...
All,
Can anyone recommend a good source of information for designing/locating pressure taps in an existing gas piping system?
I am trying to locate a tap for pressure control purposes in a 12" gas line (MAOP = 800psig). Unfortunately there is not much straight length of pipe available in the...
I am looking for a table showing pipe sizes (OD and wall thickness) per DIN piping standards, something similar to ANSI B36.10. Can anyone help? Thanks.

I have a question related to the maximum hydrotest pressure for a natural gas pipeline.
API 5L X52 pipe material, 24” OD with 0.375” wall thickness will be shop hydrotested per API requirements to a hoop stress that is a minimum of 90% SMYS. This value turns out to be an internal pressure of...
