When a leak occurs in an oil and gas pipeline, it needs to be repaired by welding. At this time, a clamp is needed to support and limit the pipeline to prevent the oil and gas pipeline from affecting the surrounding pipeline network.

When a leak occurs in the pipeline, the clamp is driven by starting the bidirectional screw rod to clamp the pipeline, which can quickly clamp the pipeline to limit and seal, reduce continuous leakage of the pipeline, and the setting of the arc-shaped electromagnet can adsorb the pipeline to enhance the sealing performance. In the process of clamping and sealing, water is transported to the inside of the sealing airbag by starting the water pump, and the gap between the clamp and the pipeline is filled by the sealing airbag, thereby reducing pipeline leakage and reducing losses during pipeline welding repairs.
