ISO Certificated Customized Marine Natural Rubber Ship Launching Airbags

Marine Rubber Airbag
Marine rubber airbag is an innovative product of Chinese own proprietary
intellectual property rights. It has wide application like ship upgrading and launching, salvage and buoyancy aid, heavy lifting. Marine rubber airbag is accepted and recognized by shipowners because of its advantages such as smaller land occupation, no need for large mechanical equipment, high safety and efficiency, flexible operation and less capital investment.

Lifting marine air bag launching for boats is China independent intellectual property rights of innovative products,the products are mainly applied to ship launching and landing,weight lifting,handling,installation of underwater buoyancy aid etc. Nowadays,Marine rubber airbags are widely used in the world.The products are less limited by space,no large mechanical equipment,can shorten the working period and save the unnecessary cost.Through years of development practice,marine rubber airbag is become more safety effective and green environment protection.

This flexible ship launching technology is accepted by more shipyards worldwide because of its advantages of saving time, saving investment, flexibility, safety. We are constantly innovating in terms of design, material usage, & manufacturing technologies throughout the years to ensure flexibility, safety, and reliability.

Up to now, more cargo vessels, barges, chemical tankers, tugboats, AHTS vessels, floating docks, and even construction caissons have all been launched using our ship launching rubber airbags. The biggest vessel launched by ship launching airbags up to 100,000DWT.

Advantages of Henger Marine Airbag

1. The production process adopts N+2 layers of cord, and ordinary companies use N+1 layers of cord.

2. The price competitive advantage is obvious.

3. It can pass various quality inspections such as BV / CIC / CCS in the industry, and comply with ISO9001, ISO17357 and other industry standards.

4. The warranty period is 18 months, which is 6 months longer than that of companies in the same industry.

5. Give free maintenance tools to provide customers with convenience

Marine Rubber Airbag Advantage

a. High bearing capacity

Inflatable rubber airbag’s main technical requirement is regulated in CB/T 3795--1996 published by China State Shipbuilding Corporation.

Henger adopts new rubber formula and high-strength enhanced synthetic-tyre-cord layer, which improves the airbag’s bearing capacity two times more than CB/T 3795--1996 standard

b. High kneading-resistance capability

When the airbag is rolling under the ship bottom, it will suffer a “kneading force” from ship bottom and ground because of not uniform rolling speed, which could case problems like delamination, layer buckling, etc.

Henger improved the manufacturing technique and raw material formula to strengthen kneading-resistance capability of the airbag and avoid worse accident .

c. New anti-explosion design of end part

The possibility of air leakage in the joint area of metal part and rubber part is also increasing as working pressure of airbag is added. After using for times under high working pressure, the airbag would burst and metal part would hurt workers.

Henger invented new anti-explosion design of the airbag end part, increasing the bonding strength and air tightness between rubber body part and end metal part. Henger airbag is working very well under higher working pressure without potential safety hazard.

d. Optimizing structure configuration

Henger 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.

e. 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.

Henger 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.

f. Higher flexibility and shock absorption capability

Henger 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.
