Pipeline monitoring for burst

[Dario2002]

Is there any good site, magazine, book, powerpoint .. anything .. about pipeline burst monitoring (natural gas transmission) using pressure drop over time?


We are using pneumatic devices which close pipeline when pressure drop is too high (change to electronic device is stared).

I need to make some rough presentation of this concept, and I would like to cover following;

- what are rules for positioning such devices on pipeline (for new pipelines), like calculating distance, rivers, roads, city, etc ..

- what pressure drop gradient to setup on device (calculation or rules)

- recommendations and requirements for equipment (covering controlling device, actuators pneumatic or electric, electronic, valves, etc. )

- anything else ..


At least, can You give me common names for this branch of equipment (we are using LBC - Line Break Control), so that I can google for some infos ..

Thank You ..

Google "pipeline leak detection" and you'll get a ton.

Location depends on type of primary sensors, diameter of pipe, length at pressure, product toxicity, degree of sensitivity of leak you need to pick up. To do it right involves quite a bit of study.

I need more "rupture" effect than "leak". I will google for that also, but i hope that someone knows for some good source text already.

This should not go into depth (not neccery), only to cover overview for "technical managment" people.

Same same. Its only a matter of sensitivity. For a large break on a short pipeline it might just need one PT, two PTs, two PTs and a flowmeter, etc. Builds from there.

Best way to determine what you need and where you need it is to do a transient analysis of the system. That way you can actually see what depressurization rates you get and what levels of sensitivity you need to pick up different leak/rupture volumes that you test at various points along the pipeline.
