Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a water seal tank pipeline welding positioning device. Background Art

[0002] The function of the water seal tank is to prevent the occurrence of backfire. After the flame enters the water seal tank through the flare gas outlet, the inlet pipe is below the water surface, thus preventing the flame from continuing to spread. Therefore, the water seal tank plays a role of safety protection in petrochemical production.
