The marine salvage rubber aribag is a buoyancy assistance device specifically designed for underwater pipeline installation and maintenance. It features high-strength rubber materials and aerodynamic structures, enabling precise pipeline positioning and buoyancy adjustment through controlled inflation. Its core advantage lies in replacing traditional steel buoys, significantly reducing the complexity and cost of underwater operations while meeting pipeline engineering demands in various scenarios such as deep-sea and shallow environments.
Core Technical Features
Modular Design
Supports parallel connection of multiple airbags, with single-point load-bearing capacity reaching hundreds of tons. Customizable to fit pipelines of different diameters (DN300-DN3000).
Foldable structure facilitates easy transportation and rapid underwater deployment, improving installation efficiency by 60% compared to traditional buoys.
Environmental Adaptability
Anti-corrosion rubber layer or/and polyester reinforcement ensure a service life of over 10 years, suitable for extreme environments ranging from -30℃ to 80℃.
Low-friction surface design reduces underwater drag force, minimizing pipeline displacement risks.
Application Scenarios
Deep-sea Pipeline Installation: Achieves pipeline suspension positioning through, reducing risks for divers.
Old Pipeline Repair: Assists in replacing damaged pipeline sections, avoiding large-scale excavation construction.
Tidal Zone Operations: Adapts to water level changes, ensuring pipeline stability in tidal environments.
Customer Value
Cost-effectiveness: Overall costs are 40% lower than steel buoys, with maintenance manpower reduced by 50%.
Safety: Zero-leakage sealing structure certified by ISO 9001, eliminating underwater accident hazards.
Sustainability: Materials have a 90% recyclability rate, complying with EU CE environmental standards.
