SINOMA's welding gas cylinder is fully made of stainless steel, and properly insulated against heat so that it is able to maintain a constant temperature and vacuum level. Various models are available to meet different customer needs. As a specialized gas cylinder manufacturer, we can customize a pressure tank to suit your requirements.

Features of Welding Gas Cylinder
1. This pressure vessel is suitable for storing super-cold liquefied gas products to maintain a constant pressure, gases including liquid nitrogen, oxygen, argon, and carbon dioxide.
2. Multiple layers of insulation are available to ensure minimized evaporation rate.
3. Built-in atomizer ensures a constant supply of gas at 10Nm3/h rate.
4. The gas storage tank provides high pressure gas.
5. Available with CGA standard joints and imported valves.
6. Vibration-damping rings withstand rough handling.
