The development of 30CrMo chromium molybdenum steel pipe and so on special seamless steel pipes for high pressure gas cylinders, from standard evolution, technical requirements to product quality and production process, is closely following the requirements of high pressure vessels such as high pressure gas cylinders, and is gradually in line with the international standards.
30CrMo chromium molybdenum steel pipe, as well as its equivalent steel such as 34CrMo4 steel, 4130 steel are commonly used to produce gas cylinders. The cylinder body made with 30CrMo chromium molybdenum steel pipe is 20% lighter than the corresponding manganese steel cylinder, but the service pressure is higher than that of manganese steel cylinder, which can be up to 19.61 MPa.

30CrMo chromium molybdenum steel pipe and other alloy steel cylinders are generally used after tempering. 30CrMo chromium molybdenum steel pipe manufacturer shall provide the mechanical inspection performance data of the samples after tempering. The strength and toughness of this kind of cylinder is higher than that of manganese steel cylinder, especially the low temperature impact toughness (- 50 ℃, V-type), good anti cyclic fatigue performance, high use pressure, light weight, small weight volume ratio, suitable for use in cold areas, oceans, aerospace, deep wells and other special environments; and the lighter and smaller weight volume ratio of high-pressure cylinder has become the development trend of cylinder manufacturing industry in recent years.
