[0002] Pipeline gas transmission stations are various operation stations established for pipeline transportation of natural gas or associated petroleum gas. According to the location of the gas station along the pipeline, it is divided into the starting gas compressor station, the intermediate gas compressor station and the terminal gas filling station. The starting gas compressor station is located near the gas field gathering center or the processing plant. It provides pressure energy for the natural gas and performs gas purification, gas mixing, pressure regulation, gas metering, pig sending and other operations. The intermediate gas compressor station is located along the transportation pipeline, mainly to pressurize the natural gas that consumes pressure energy during transportation. The terminal gas filling station is located in the gas storage reservoir. In the gas transmission station, the pipeline is generally supported and fixed by a bracket.
