Product Description
The variable diameter pipeline sealing airbag is a device used for sealing underground pipelines. It is primarily composed of soft metals and multi-layer polymeric materials to form an airtight sealing bag. Both sides of the bag are equipped with waterproof adhesive strips that can withstand high temperatures. When the inflation reaches a certain pressure, the strip will tightly adhere to the pipeline and cable, achieving complete waterproofing. In addition, the inflation port contains self-filling polymeric materials to prevent gas leakage.
Product Parameters
The variable diameter pipeline sealing airbag comes in various specifications and can be customized according to the diameter and material of the pipeline.
