Vessel Marine Rubber Airbag Length 10m To 20m Black Ship Pulling Airbags

Marine Vessel Launching Air Bag Length 10m to 20m Boat Pulling Airbags

Products introduction

The typical diameters of airbags are 2.6ft (0.8m), 3.3ft (1.0m), 3.9ft (1.2m), 4.9ft (1.5m), 5.9ft (1.8m), 6.6ft (2.0m) and 7.9ft (2.4m). The effective length can be specified by end user, and typical varies from 19.7ft (6m) to 98.4ft (30m), depending on the breath of the vessel bottom. The number of synthetic-tyre-cord layers can be 3 to 12, depending on the required working pressure

Rubber layers

A] The out side rubber layer that covers the outside of rubber airbag to protect under layers from abrasion and other external forces. This compound has sufficient tensile and tearing strength to withstand any condition and hard usage.

B] The inside rubber layer seals pressurized air inside marine airbags. 
The cord layers are made of synthetic tire cord which commonly used on tires, that  hold the internal pressure and distribute stress evenly. So they can provide strong efficient reinforcement for the airbags.
 

Flexible balloon like an elastic cushion, it make the hull in the process of launching free pitch, keep the bottom has a larger contact area, makes the stress of the hull very ease, so that the hull structure, on the surface of the paint (coating) will not be damage.

Performance Calculation Principle of Airbags

The bearing capacity of marine air bags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.Because of the flexibility of marine air bag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of air bags will vary as well as the contact area.
