FAQ

Q1: Which pipe materials and diameters are compatible with these airbags?

SunKai Inflatable Plugging Airbags work with most pipe materials, including PVC, concrete, steel, and cast iron. Standard sizes cover diameters from 50mm to 3000mm. For special diameters or complex conditions, our technical team can provide customized solutions.

Q2: How long can the airbag maintain a seal?

When properly inflated and used under normal conditions, the airbags can maintain a tight seal for up to 72 hours. For long-term projects, check the pressure every 12 hours and adjust as needed. The airbags are reusable for multiple projects.

Q3: What is the maximum pressure the airbags can withstand?

The internal pressure varies by size. Standard models can be inflated to 0.02–0.15 MPa and resist external water pressure up to 0.3 MPa. For high-pressure pipelines, contact our sales team to select reinforced or thickened airbags for safe operation.

Q4: How should the airbags be stored after use?

Fully deflate the airbag, rinse off dirt or sediment with clean water, and air dry. Store in a cool, dry place, away from sunlight, heat, or sharp objects. Using a protective bag for storage will extend the lifespan and maintain performance for repeated use.

Q5: What precautions should be taken during inflation?

Use a pressure gauge to control inflation and avoid overpressure. Inflate gradually to prevent uneven stress. Ensure the inside of the pipe is free from sharp edges, or wrap the airbag with a protective layer to avoid damage and maintain sealing performance.
