Description

Technical Field

[0002] Fire protection engineering covers a series of measures and facilities taken to prevent fire and its spread. The core goal of fire protection engineering is to protect life and property from fire hazards. Through comprehensive measures and facilities, fire prevention, timely control of fire spread, effective fire extinguishing and rescue work are carried out. During the construction of the fire protection system, pipes need to be welded to ensure that the pipes can be welded and repaired quickly and effectively.

However, the fixing effect of the pipe in the existing fire protection engineering welding device is not ideal, and the pipe cannot be rotated after being fixed. It needs to be released and manually rotated, which is very time-consuming and reduces the welding efficiency. Utility Model Content
