Main Performance features of dewar gas cylinder:
1. It is mainly used for transportation and storage of liquid oxygen dewar tank, liquid nitrogen, liquid argon, liquefied natural gas and liquid carbon dioxide.
2. Adopt high vacuum multi-layer adiabatic mode to ensure low evaporation rate.
3. The built-in carburetor automatically provides 10Nm3/h of stable and continuous gas.
4. The gas phase space overpressure gas is preferred in the solar term device.
5, the use of international general CGA standard joints, all imported valve configuration.
6. Unique damping ring design meets frequent transportation requirements.
7. Suitable for: electronics, scientific research, chemical industry, welding, LNG supply and other industries.

Q1: How to ensure your cylinders quality?
A: we have been in this field for more than 20 years. Our products have been sold almost all over the world. We allow 3rd party inspections before shipment ( on buyer's account) And we can supply certificate of quality accordingly.
Plus we have six machinery equipments to test material and cylinder:
1.spectrum analyzer to detect chemical analysis;
2.mechanical function to make tension test and bending test;
3. X-ray silent detection to inspect circumferential weld;
4.Hydraulic bursting test;
5.Hydraulic testing;
6.Air tightness test.
Q2: About the brand name of the products?
A: In general, We use our own brand "DSW", if you have requested, Both OEM and ODM arealso available.
Q3:Can you provide a sample?
