Marine Rubber Airbag Manufcturer | Ship Launching Airbag

Marine Rubber Airbags Introduction

A marine rubber airbag is based on the log rolling method, using soft rubber for lifting and bearing. It is an innovative product with independent intellectual property rights in China. It is widely used in the fields of heavy lifting, ship launching and upgrading, caisson lifting, and underwater engineering buoyancy aid. Marine rubber airbags are not restricted by space and heavy machinery, which can effectively shorten the construction period and save much money.

Marine Rubber Airbags Application

1. Ship Launching and Upgrading

After more than 20 years of development in China, marine rubber airbags have proved to be the most reliable and stable technology for ship launching and upgrading. It is suitable for tonnage flatbed to 10,000 tonnes giant ships. Meanwhile, foreign shipyards, dockyards, and port construction companies also widely recognized marine rubber airbags. The ship launching and upgrading technology of marine rubber airbags has also been vigorously promoted in America, Europe, Southeast Asia, and other markets.

2. Lifting and Moving

Marine rubber airbags can be used for lifting, launching, moving, and transporting caissons in harbor construction works.

3. Buoyancy Salvage

Due to the buoyancy and carrying capacity of marine rubber airbags, they are also widely used in wreck salvage and buoyancy rescue.

Jerryborg Rubber Airbags Advantages

1. High Load Carrying Capacity

Main technical requirement of marine rubber airbag made by Jerryborg Marine are complied to ISO 14409 “Ships and marine technology – ship launching air bags”.

Jerryborg uses a new rubber formulation and a high-strength reinforced synthetic tire cord layer, making the airbag’s load-carrying capacity twice as high as the ISO 14409-2011 standard.

The synthetic-tyre-cord layer of Jerryborg marine airbag adopts 1480dtex/2 chinlon tyre cord.

The strength & durability of airbag improves 40%, compared to polyester tire cord.

1480dtex/3 chinlon tyre cord is applied to specially designed airbag sometime.

2. High Kneading Resistance

Due to the uneven rolling speed, when the airbag rolls under the ship, it is subject to the ‘kneading force’ of the ship’s bottom and the ground, which is prone to delamination, layer buckling, and other problems.

Jerryborg has improved the production process and raw material formula to enhance the kneading resistance of airbags to avoid more serious accidents.

Each layers of airbag are painting with specially formulated mucilage to dissolve dust & impurities.

The specially formulated mucilage

also higher the adhesiveness among each layers to guarantee the air tightness.

3. New End Metal Parts Anti-Explosion Design

As the working pressure of the airbag increases, the possibility of air leakage in the area where the metal part meets the end rubber body increases. After repeated use at high operating pressures, the airbag will burst at the end metal part, causing injury to nearby workers or facilities.

Jerryborg invented a third-generation anti-explosion design for the airbag ends, which improves the bonding strength and airtightness of the rubber body part to the metal part of the ends. Jerryborg Marine’s airbags work well at higher operating pressures without potential safety hazards.

4. Optimizing Structure Configuration

Jerryborg built a strength and intensity model to test compression performance, stress intensity and direction. After testing for many times, we got the stress changeing regularity and optimized structure configuration design. The new optimized airbag successfully passed blasting experiment and achieved good performance in practical use.

Hydraulic Blasting Test is an all-around ultimate test for the performance, material, structure design, manufacturing technique of marine airbags.

The testing result of Jerryborg Marine Airbag is beyond industrial standard

5.Good Abrasion-resistance Performance and High Ageing Resistance

The airbag is working under bad and poor condition, suffering from long time sunlight exposure, seawater corrosion, impurities pollution, etc. The surface of airbag must be equipped with high capability of abrasion resistance, ageing resistance, corrosion resistance.

Jerryborg airbag is made of natural rubber with special ingredients and unique manufacturing method. The finished airbag could working very well under above mentioned bad and poor working condition.

6.Higher Flexibility and Shock Absorption Capability

Jerryborg airbag is manufactured with unique integral twining technique. The airbag wall thickness is uniform with secondary seam in overlap joint. When rolling in slope and uneven ship path, the flexible airbag is helpful to reduce structure stress and ship launching risk.
