Large-volume steel seamless gas cylinders are mainly used for the transportation of CNG (compressed natural gas). They are made of 4130X seamless steel pipes and can contain natural gas at 20MPa or 25MPa. In accordance with the authoritative American standards and relevant international standards, the company has formulated the enterprise standard Q/LZB1-2016 "Large Volume Steel Seamless Gas Cylinders", which has made strict regulations on the design, manufacture, inspection and acceptance of such products

Experimental results

The actual bursting pressure of the gas cylinder is not less than 2.5 times the nominal working pressure of the gas cylinder. After the gas cylinder bursts, there is no debris in the cylinder part of the cylinder body, and the product is qualified for the bursting test. The horizontal and vertical incisions on the shoulder of the steel cylinder are neat and uniform in thickness, which meets the production standards of the product.

According to JB4732-1995 "Steel Pressure Vessels-Analysis and Design Standards" (confirmed in 2005), TSG R0004-2009 "Safety Technical Supervision Regulations for Stationary Pressure Vessels", Q/LZB3-2014 "Station Storage Gas Cylinder Containers" standards Gas cylinders produced.
