CNG long-tube trailer mainly consists of five parts: trailer, framework, large-cubage seamless steel cylinders, fore safety cabin and back operation cabin. Both ends of the large-cubage seamless steel cylinder have machined outside and inside screw threads. The outside screw threads of both ends connect with the setting flanges. The setting flange is fixed on the supporting plates of both ends of framework by bolts. Screw the end plugs into the inside threads of the cylinder mouth. Connect tube fittings with the end plugs. There set burst disks on the fore cabin, forming safety cabin. There set inlet and outlet tubes, blowdown tubes, thermometer, pressure gauge, quick-connect joint and burst disks fitting on back cabin, forming operation cabin.

CNG long-tube trailer is the gas source of CNG filling sub station. It also can transport CNG for the civil gas system. It is an effective supplementary method to the pipe conveyance of gas. Its technology is simple and it occupies small ground. It has the following traits: 1. Import valves with high quality; 2. Advanced manufacture technology, fine manufacture
CNG storage cylinders groups for gas station is the necessary equipment for nature gas filling station. The equipment use compressors to increase the pressure of nature gas in pipe network or CNG trailer, then store as gas filling source for gas station, or as the peak-regulating gas source of nature gas pipe network, its working pressure can reach 25 MPa.
