Variable Diameter Pipeline Sealing Airbag – Adapting To Different Diameter Pipelines
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.
