There are equipments, pipelines, tanks, valves and other chemical containers used in the production, transportation and storage of hazardous chemicals in chemical enterprises. Once these equipment or pipelines are damaged and poorly sealed, it is easy to cause dangerous chemicals Leakage that will not only lead to economic losses of enterprises, but also lead to safety production accidents such as house fires, explosions and personnel poisoning, resulting in serious losses of personnel and property.
 In order to ensure the safe use of chemical containers, it is necessary to strictly control the welding quality of the container equipment, adopt a reasonable welding process, and strictly control the welding operation process to ensure its good sealing.
