Product Description

4m Marine Airbags Low Maintenance Superior Floatation Puncture Proof Easy To Repair

 

Description

 

Our Ship Launching Balloons are engineered for versatility, supporting ship launching, salvage operations, and heavy lifting. With sizes ranging from 1m to 5m, they accommodate various vessel weights and types. The multi-layered rubber construction ensures puncture resistance, while the oil- and chemical-proof design enhances durability in harsh marine environments. Quick inflation/deflation saves time, and their compact storage makes them a practical choice for shipbuilders and rescue teams. A reliable, reusable alternative to steel rollers and slipways.

FAQ

 
1. How long do they last?
10–15+ years with proper maintenance, and 500+ launch cycles before significant wear.
 
2. What pressure do they operate at?
Working pressure: 0.3–0.8 MPa (43–116 psi). Burst pressure exceeds 3.5x working pressure.
 
3. Are they resistant to saltwater and chemicals?
Yes, they resist seawater, oils, diesel, and mild acids/alkalis (pH 4–10).
 
4. Can they handle extreme temperatures?
Operational range: -40°C to +80°C (-40°F to 176°F) without cracking or softening.
