Standard for color marking of gas cylinders

- Dec 20, 2017 -

The structure is classified as seamless gas cylinders and welded cylinders, and steel cylinders (including stainless steel cylinders) are classified from material. Aluminum alloy gas cylinders, composite gas cylinders, other materials, gas cylinders, from the filling media classified as permanent gas cylinders, liquefied gas cylinders, dissolved acetylene cylinders, from the nominal working pressure and hydrostatic test pressure on the classification of high-pressure cylinders, Low pressure cylinders.

The nominal volume is not less than 1000L, and is used for movable pressure vessels that can be repeatedly inflated without an adiabatic device for compressed gas. Commonly used are oxygen cylinders, acetylene bottles and so on. Car natural Gas Bottle: General volume in 50-140 liters, pressure 20MPa, outside diameter 325mm. There are now two kinds of full cylinders, a ring-winding, winding bottles are new technology, security is higher, light weight, winding layer material is glass fiber, cylinder main material 30CrMo.
