Dry Dock Inflatable Rubber Airbags for Ship Launching Marine Salvage

Dry Dock Ship Launching Marine Salvage Inflatable Marine Airbags

The airbag for heavy lifting and launching and launching of ships is an innovative product with China's independent intellectual property rights. It is widely used in ship launching and launching, caisson lifting and transporting, handling of other heavy objects, and floating aid in underwater installation projects. field. The application of marine airbags is less restricted by space and does not require large-scale machinery and equipment, so it can shorten the engineering cycle and save a lot of money. After more than 20 years of development and practice, it has been proved that this product has the characteristics of safety, efficiency, green environmental protection, mobility and flexibility.

Manufacturing technology

Whole Intertwine Technology
"HENGER" Airbags overall frame structure uses cross whole intertwine technology, the overall structure is more reasonable, texture clear, no juncture, high loads, more safety than lap technology (roller), more than 20% bearing capacity.

Framework

“HENGER” airbag structure are consist of the outer rubber + synthetic cord reinforced rubber layers.Its shape characteristics: central body cylindrical + tapered on both ends. Cord layers: 4,5,6,7,8,9,10,11,12 layers.

 Product Advantage

1. 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.

The synthetic-tyre-cord layer of Henger marine airbag adopts dipped Nylon-6 1400dtex/3-V2 tyre cord.

The strength & durability of airbag improves 20%, compared to polyester tire cord which is widely used by friendly competitors.

2. 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 .

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.

While most of friendly competitors cut this process in production to save manufacturing cost.

3. 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.

4. High strength galvanized anti-release structure

casting metal part with chemlok coating.

chemlok coating strengthens the bonding between metal part and rubber body after vulcanization.anti-release structure of the metal part makes the connection more tight.

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

The testing result of Henger Marine Airbag is beyond industrial standard
