Low maintenance cost natural gas centrifugal compressor 

• Our Cng natural gas compressor offering a full range of highly reliable oil-free piston compressors , air cooled or water cooled cng compressor collect gas from oil wells, gas wells, after gathered, CNG natural gas is transferred through pipes to storage tanks, or to gas station filling cylinder or directly fill car. high pressure 20mpa,25mpa cng filling compressor ,well head gas compressor ,offshore cng compressor are usually cooled by air.
• Cylinder.Gas is compressed in the cylinder, most compressor type use double-acting cylinder. A cylinder’s maximum allowable working pressure should be rated are least 10% greater than the design discharge pressure. Wear compatibility is a criterion for selecting cylinder materials. There are casting type and forged type. For oxygen , ammonia,co2 include water , the cylinder is made of stainless steel ,which will ensure the outlet gas clean. Air cooled cooling systems is used for small compressor cylinder, cooled water can remove the heat which is beneficial to the performance and reliability of the compressor.
• Compressor valves. Suctions valves admit gas into the cylinder, discharge valves is used to evacuate compressed gas from the cylinder. Stainless steel valve Plate valve is most common type ,be very important for compressor. opening of the valves depend on the pressure differential existing between the cylinder inner and outer. Herobiger valves are optional .
