燃气设备及管网是保障城市可靠供气的重要设施，其输送的是可燃介质，而且分布点多面广，涉及千家万户的用气。燃气设备及管网分布于城市的各个位置，覆盖面广，有处于郊外的高压场站和管道，有位于高层建筑物或多层建筑物的燃气架空管和立管，有设置在市政道路旁的区域调压站和设置居民小区的楼栋调压箱，以及对燃气设备及管网进行监控的SCADA 系统等

燃气设备将液化气（天然气）和空气（或多种气源）按一定比例掺混在一起达到用户需要的燃气热值，可以满足民用和工业等不同用户的要求。燃气设备包括文丘里式混气机、随动流量混气机、高压比例式混气机，压缩天然气减压站，液化气设备，天然气设备，燃气调压箱，CNG减压站，燃气设备，液化气气化站，LPG气化设备，LNG气化设备，CNG减压设备，燃气调压设备，燃气调压，调压站，减压站，调压箱，液化气空混设备，液化气气化器等等。

强制气化设备：从小型到大型，从壁挂式到立式以及空温式，从50公斤/小时到30000公斤/小时，还有做为临时用气的移动式可装可卸站房。液化石油气强制气化设备在中国市场上已经使用二十多年，技术和质量上的可靠性越来越成熟，已被我国工业、农业、商业、军事上得到广泛的应用和认可。

混气设备：包括比例式混气、随动流量混气、文丘里引射式混气、人造煤气以及调峰作用和天然气前期送气替代，使混合达到天然气燃烧、煤气的燃烧值起到了方便、快捷、实用。天然气设备也有其特点，用途也同样和液化石油气一样广泛。
城市门站、区域调压设备以及调压箱和楼栋调压箱：在天然气管道能达地区得到广泛的应用。根据不同的用户生产不同的城市门站。区域调压设备以及调压箱和楼栋调压箱以满足工业和居民的不同用途，使工业户和居民用上便宜、洁净的能源并且天然气无污染且价格便宜。

撬装设备（压缩天然气）减压站：适用于天然气管道达不到的地区，将天然气压缩至160Kg/m2到220Kg/m3。用拖车将压缩天然气运至需要的工业用户或居民用户，然后经过二级减压或三级减压或再经过区域调压设备和调压箱到用户，使这些用户也能用上绿色洁净便宜的能源。液化天然气就是将天然气冷冻液化或液态，使其体积缩小，以便于运输。到目的地后再使其气化，气化后同天然气管道输气，撬装天然气一样很方便快捷的输送到工业和居民用户。

Gas equipment and pipe network is an important facility to ensure reliable gas supply to the city. It transports flammable media and has a wide distribution point, involving thousands of households. Gas equipment and pipe networks are distributed in various locations in the city, covering a wide range of high-voltage stations and pipelines in the suburbs. There are gas overhead pipes and risers located in high-rise buildings or multi-storey buildings, which are located next to municipal roads. Regional pressure regulating stations and building pressure regulating boxes for residential buildings, as well as SCADA systems for monitoring gas equipment and pipe networks, etc.

Gas equipment mixes liquefied gas (natural gas) and air (or multiple gas sources) in a certain proportion to achieve the gas heat value required by users, which can meet the requirements of different users such as civil and industrial. Gas equipment includes venturi mixers, follower flow mixers, high pressure proportional air mixers, compressed natural gas decompression stations, liquefied gas equipment, natural gas equipment, gas pressure regulating tanks, CNG decompression stations, gas equipment, Liquefied gas gasification station, LPG gasification equipment, LNG gasification equipment, CNG pressure reduction equipment, gas pressure regulating equipment, gas pressure regulation, pressure regulating station, decompression station, pressure regulating tank, liquefied gas air mixing equipment, liquefied gas Gasifier and so on.

Forced gasification equipment: from small to large, from wall-mounted to vertical and air-temperature, from 50 kg / h to 30,000 kg / h, as well as mobile loading and unloading station as temporary gas room. Liquefied petroleum gas forced gasification equipment has been used in the Chinese market for more than 20 years, and the reliability of technology and quality has become more and more mature. It has been widely used and recognized by China's industry, agriculture, commerce and military.

Gas mixing equipment: including proportional mixing gas, follow-up flow mixing gas, venturi ejector mixing gas, artificial gas and peaking action and natural gas pre-gas supply replacement, so that the mixing reaches natural gas combustion and gas combustion value It is convenient, fast and practical. Natural gas equipment also has its own characteristics, and its use is also as extensive as that of liquefied petroleum gas.
Urban gate stations, regional pressure regulating equipment, and pressure regulating boxes and building pressure regulating boxes: widely used in natural gas pipelines. Different city gate stations are produced according to different users. Regional pressure regulating equipment, as well as pressure regulating boxes and building pressure regulating boxes, to meet the different uses of industry and residents, so that industrial households and residents use cheap, clean energy and natural gas is pollution-free and cheap.

Washing equipment (compressed natural gas) decompression station: Suitable for areas where natural gas pipelines are not available, compressing natural gas to 160Kg/m2 to 220Kg/m3. Use the trailer to transport the compressed natural gas to the industrial users or residents who need it, and then pass the secondary decompression or tertiary decompression or pass the regional pressure regulating equipment and the pressure regulating box to the user, so that these users can also use the green clean and cheap. Energy. Liquefied natural gas is the liquefaction or liquid state of natural gas, which is reduced in size for transportation. After it has arrived at the destination, it will be gasified. After gasification, it will be transported to the natural gas pipeline, and it will be easily and quickly transported to industrial and residential users.
