Performance:

Gas cylinders are high-pressure containers. To ensure safe use, in addition to having corresponding high tensile strength and yield strength, gas cylinder tubes are also required to have high elongation and impact toughness.Physical and chemical test: composition, non-metallic inclusions, sample heat treatment performance test,

Ensure that all indicators meet customer requirements.

Production process:

① Large-diameter pipe piercing - The method of manufacturing tube blanks for gas cylinders by piercing steel ingots (billets) and pipe jacking is often adopted by steel pipe factories, heavy machinery factories, etc. This method is suitable for manufacturing large-diameter, thick-walled, high-capacity high-pressure gas cylinders and containers.

② Pipe rolling - After heating the steel ingot (or round billet, continuous casting billet) and piercing it, it is hot-rolled into a tube blank through a periodic pipe rolling mill, an automatic pipe rolling mill, a continuous pipe rolling mill, etc. Then, it undergoes hot sizing, straightening, and finishing to become a finished seamless steel pipe. This is one of the most important methods used for producing large quantities of gas cylinder tubes.

Conclusion

The development of special seamless steel pipes such as high-pressure gas cylinders, from standard evolution, technical requirements, to product quality and production processes, has all been closely following the demands of high-pressure gas cylinders and other high-pressure vessels, and gradually aligning with international standards.

With the renewal and improvement of smelting, pipe rolling and large pipe piercing equipment, the continuous modernization of process technology and the enhancement of management level, China has developed the capacity to produce seamless steel pipes for various high-pressure gas cylinders and other high-pressure vessels, which can basically meet the production needs of the high-pressure vessel manufacturing sector.
