1. Interface shape: The interface of new gas tanks usually adopts standardized interface shape, such as CGA (Compressed Gas Association) standard. However, the shape of the old gas tank interface of different manufacturers may be different.
2. Connection mode: The interface of new gas tanks usually adopts threaded connection mode, such as CGA 580 (for gas with pressure less than 3000 psi) or CGA 590 (for gas with pressure greater than 3000 psi). The interface of the old gas tank can be connected in other ways, such as flange connection or pressure lock connection.
3. Safety performance: The new gas tank interface design is safer and more reliable, which can effectively prevent gas leakage and accidents. Interfaces are usually equipped with valves and sealing devices to ensure the safe storage and use of gas. The interface of the old gas tank may not have these safety designs.
It should be noted that different types of gases may have different interface requirements, so when using gas tanks, you should carefully check the interface matching between gas tanks and equipment, and ensure correct connection and operation to ensure safe use.
