Marine Rubber Airbags 008mpa,
Floating Marine Rubber Airbags,
Ship Launching Landing Marine Airbags
The main supporting elements of the slip are air bag . Ship transferring from the building area to the slip is produced approaching the deflated air bag under the vessel and inflating with compressed air. The launching is made on the air bags used as the rollers. This launch can be both uncontrolled and controlled. In the latter case the launching speed is regulated by the traction mechanism which is located at the head of the slip.
The distance between the air bags depends on the light-ship, the length and width, but not more than 6 m from the bag centers. To install the bag the space at least 25 cm in height and width at least the half of the circumference of the air bag is required.
1. Outer and inner Rubber Layer
The outer rubber layer that covers the outside of marine 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.
2. synthetic-tire-cord layer for reinforcement
The reinforcement cord layers,which are made of synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and distribute stress evenly. So they can provide strong efficient reinforcement
3. End Fittings
End fitting include Air Tightness swivel and Safety Air Inlet.
*These end fittings are enclosed when airbags leave our factory.

The engineering work under water line shall wholly be finished, especially those equipments, valves and others that are to be installed at the openings under ship waterline,the installations should be approved by inspection. All the burrs, welding beading and the like on the ship bottom or appendages should be ground away. All the welds on the shell plate must pas inspection and tightness test. The main dimensions of the ship should be measured up and the mark of loadline must pass inspection. All the paint work of the shell plate has been finished.
2 Ramp way
The ramp way on which the airbags will rolling should be cleaned and be clear of sharp fends such as iron nail. The ramp way should be leveled and the level error from left to right should less than 80mm. The ground caved in should be filled up and the ground bearing capacity should be relatively equalized. The ramp made of mud land, sanded land, sands or concrete, however, its bearing capacity should be twice as big as the working pressure of airbags. The slope of ramp is to be determined according to the size of the launching ship and is generally no bigger that 1/7. In the range of the whole length of the ramp way, the shape may be of multiple combination with slope line, are line and others. However, the ship bottom should not contact the ground even when the airbags are at their lowest working height. The ramp way should extend into water for certain length.
In general, a slow winch is to be selected, its veering speed is about 9-13/m/min. The moving speed of a ship must not be more than 6m/min with the control of hauling force of winch wire. If the ship weight is less than 200t, the moving speed can be increased properly. The wire must be inspected and replaced regularity.
The type and capacity of the air compressor is to be selected according to the total volume of all the airbags provided for the launching and time required for air filling and the air pressure. The gas tank of air compressor should be installed with adjustable pressure limiting valve.
1.For ship upgrading, conversion or new/repair launching (Ship launching airbags)
