Description

[0002] At present, pipe braziers are mostly split type, and the split type electric hydraulic pipe brazier has the following core defects, which seriously restrict the electrical construction efficiency and scene expansion.

[0004] 2. High risk of hydraulic pipeline damage: the main body is displaced with the pipeline (single displacement is ±8~15 cm) during pipe brazing, the hydraulic hard pipe is subjected to tensile stress (peak value is 25 MPa) and vibration impact (frequency is 5~10 Hz), and the annual damage rate is more than 30%; the hard pipe needs to be disassembled for maintenance (time consumption is more than or equal to 30 minutes), which increases the cost and reduces the operation efficiency.
