Ce Certificated Barge Ship Landing Rubber Airbag For Launching - China

CE certificated barge ship landing rubber airbag for launching

Inflatable ship landing airbag also known as rubber airbag, ship air bags, ship launching airbag, ship salvage airbag, boat salvage airbags, inflatable airbag, ship lifting bag, air balloon, made by rubber & multi layer of rubber-dipped tyre fabric.

Airbags are widely used in launching and landing ship/ boat/vessel, lifting and moving heavy goods, salvaging stranded boats.

Marine airbags are very popular with shipyard, ship owner, and marine supplies company now.

Structure

1) Outer Rubber Layer

The outer rubber layer that covers the outside of ship 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) Inner Rubber Layer The inner rubber layer seals pressurized air inside ship airbags.

3) Synthetic-Tire-Cord Layer as 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.

Material Ship rubber airbags for docking and undocking are constructed of synthetic-tire-cord layers; inner and outer rubber layers are sometimes added.

All materials used are vulcanized.

Air tightness test: Without carrying any load, fill the air bag till the internal pressure of the air bag reaches rated working pressure.

After 1 hour.

The pressure loss should be less than 5 % of initial pressure.

Bursting test: Fill the air bag with water until the air bag bursts.

The water pressure at the time of bursting shall be no less than three times of rated working pressure.

The Requirements of Ship Launching and landing, Ship and Relevant Equipment.

1 - Ship

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 rock, 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(best angle 5~6°).

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.

3 - Winch 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.

4 - Air compressor 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.
