Abstract:
A sampling probe for mounting within an opening in a hydrocarbon gas pipeline for obtaining sample gas from the pipeline, the probe supplying gas to a pump for sampling gas from the pipeline through the probe and to a sample bottle while the pump and probe are heated by a heater to minimize condensation of gas between the pipeline and the sample bottle, said probe comprising:a lower body with a throughbore for extending within the pipeline; an upper body with a connected throughbore for extending outwardly from said pipeline; said upper body and said lower body being rigidly connected and formed from a metal having a thermal conductivity of at least 80 BTU/Ft Hr/Ft2/Â° F.; and an outer diameter of said lower body of said probe being greater than at least about 80% of an inner diameter of said opening in said pipeline.
