Pipeline Hydrostatic Test Temperature Probe Location
Pipeline Hydrostatic Test Temperature Probe Location
(OP)
How far from surface piping should buried temperature probes be installed to avoid temperature fluctuation due to ambient temperature change during a hydrotest. I'm trying to specify the location of temperature probes for a buried pipeline hydrostatic test. I've found several sources online that specify the the temperature probes should be buried .5Km from any surface piping. Several people in my company want to place the buried temperature probes within 200 ft of the launcher where the test equipment is located. The temperature probes I'm referring to are the ones that attach to the pipeline. I've also seen references that specify buried temperature probes not attached to pipeline.

Making it inside the fenceline of the facility makes sense to me.
For longer lines you need at least a mid point one at a suitable point ( road crossings etc) if you can.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
