Natural gas transmission station is the general name of various process stations in gas pipeline engineering, and its main functions are to receive natural gas, pressurize pipeline natural gas, distribute natural gas, distribute gas, store gas peak shaving, send and receive pigs, etc. The positions in the gas pipeline are: the first station of gas transmission, the end station of gas transmission and the intermediate station (the intermediate station is divided into compressor station, gas distribution station, etc.) and some auxiliary stations.
Natural gas stations play an important role in the transportation of natural gas, so it is necessary to detect gas pipeline leaks and internal leaks in gas station valves in natural gas stations to reduce economic losses caused by leaks and ensure the safety of workers.
* ultrasonic leak detector, suitable for all-round monitoring of natural gas stations.
Through non-contact and long-distance testing, real-time monitoring of the operating status of the equipment under test and gas pipeline leakage (welds, flange connections, etc.) can be realized, and the main noise sources of abnormal operation and pressurized gas leakage of the equipment under test can be detected, and when the leakage noise signal is detected, the leakage alarm command will be issued.
*Ultrasonic valve leakage detector is suitable for monitoring valve leakage in natural gas stations.
By detecting the ultrasonic wave (sound pressure change in the ultrasonic frequency band) generated by the leakage of pressurized gas at the valve, it is possible to identify the occurrence of continuous small valve leakage, and realize real-time monitoring of the operating status of the tested valve and valve leakage. When the main noise source of pressurized gas leakage is found and the leakage acoustic signal is detected, a matrix data model library is established, and the leakage event alarm is issued after acoustic data comparison and temperature correlation analysis.
Handheld ultrasonic leak detector for natural gas station inspection.
Hand-held explosion-proof ultrasonic leak detector for inspection to detect various gas leaks in pressure pipelines, production process pipelines, valves, and equipment. The instrument can detect small gas leakage through the capture, amplification, detection and decoding of ultrasonic waves, and convert the leakage phenomenon into a sound signal that can be heard by the human ear, and display the leakage intensity value on the instrument screen at the same time.
