DESCRIPTION:
OXYGEN CYLINDER 240 CFTThe world’s first natural gas cylinders were invented in China during the唐代中国人钻深孔以检索天然气，并使用竹管收集和运输。[1][2][dubious]
有关气缸材料的详细讨论，请参见压力容器.
Design codes and application standards along with the cost of materials dictated the choice of steel with no welds for most gas cylinders, treated to be anti corrosive. There have been some newly developed lightweight gas cylinders from stainless steel and composite materials. Due to the very high tensile strength of carbon fiber, these vessels can be very light, but are much more difficult to manufacture.[3]
高压缸的运输受到世界各地的许多政府的监管。对于要运输的国家，管理机构通常需要各种测试。在美国，这个权威是United States Department of Transportation（点）。同样，在英国，欧洲运输法规（ADR）也由运输部（DFT）实施。对于加拿大，这个权威是Transport Canada(TC). Cylinders may have additional requirements placed on design and or performance from independent testing agencies such asUnderwriter’s Laboratory(UL). Each manufacturer of high-pressure cylinders is required to have an independent quality agent that will inspect the product for quality and safety.
Within the UK the“competent authority“— the DfT — implements the regulations and appointment of authorised cylinder testers is conducted by UKAS, who make recommendations to the VCA for approval of individual bodies.
在各种圆柱体上可能会执行多种测试。一些最常见的测试类型是hydrostatic test, burst test,抗拉强度,Charpy impact test和压力循环。
During the manufacturing process, vital information is usually stamped or permanently marked on the cylinder. This information usually includes the type of cylinder, the working or service pressure, the serial number, date of manufacture, the manufacture’s registered code and sometimes the test pressure. Other information may also be stamped depending on the regulation requirements.
多次使用的高压圆柱体可以进行静静止或超声测试，并且每隔几年就可以进行视觉检查。[4]在美国，根据气缸及其服务，需要每五年或每十年进行一次静水/超声测试。氦气气缸充满时可能具有最高的压力，约1000个气氛
