Marine Rubber Black 1.5x16m Ship Launching Airbag

Marine Rubber Airbag Introduction

Marine Rubber 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.

Marine Rubber Airbag Application

1.Ship Launching & Upgrading

With more than 20 years development in China, marine rubber airbag is proved to be the most reliable and stable technique for ship launching & upgrading. It is applicable from tons of flat board to ten thousand tons of huge ship. Meanwhile, marine rubber airbag is also widely acknowledged by foreign dockyards, shipyards, port/harbour construction companies. Ship launching & upgrading technique with marine rubber airbag is also highly promoted in the markets, such as America, Europe, Southeast Asia.

2.Weight Lifting & Moving

Marine rubber fend could be applied to caisson lifting, launching, moving and transporting in port constructing projects

3.Buoyancy Aid & Salvage

Because marine rubber airbag has buoyancy force and load-bearing capacity, it is also widely used in sunken vessel salvage and Buoyancy Aid.

Technical Requirement

According to CB/T 3795--1996, marine rubber fender should meet the following requirements.

• Dimensional Deviation:

Diameter & Effective Length Deviation: ±2%

Total Length Deviation: ±4%

• Amount of Elastic Deformation: diameter deformation amount ≤ 5% under 1.2 times working pressure.
• Safety Factor: >4.5
• Air Tightness: depressurization < 5% after 1hour inflation
• Surface Quality: fairing line shape, no crack, no bubble, no double skin, no impurities, no distinct dirt and other apparent defect.
• Anti-explosion design of end part.

Notice during using

1. While the shipping air launching airbags are in use, strictly control the pressure, prohibit use of exceeding the work pressure.

• The surface in contact with the shipping lifting airbag must not have a sharp protruding hard object to prevent the airbag skin from being pierced.
• Try to avoid distortion in the length of the airbag.
• Should avoid the inflatable load after we have in charged the air into the airbag.
• For example, when the ship is erected, when the lifting airbag has lifted most of the hull, remove most of the pier and fill the rolling airbag. If there are 1-2 piers still under compression, the internal pressure between the airbags should be adjusted so that the ship can be removed from the side of the ship. And the pier can not be manually used. Otherwise, the ship may be forced to impact the airbag that has been filled.
• Another example is the collision with other objects for various reasons during the ship transfer process. In severe cases, the impact airbag may be damaged.
• Before long time no use or re-use after repair, we should carry out the air filling test again. The air internal pressure should be the same as the factory test value of our factory. The test worker should keep away three meters from the airbag during the test. If the airbag repaired by a large area damage, we should decrease the use pressure. Therefore, for the airbag often used, still need the above test once a year.
• Do not drag the ship launch airbag on the hard ground.
