Dia 0.5m-4.5m Marine Salvage Airbag For Launching The Ship Dry Dock Airbag 1

 

1. Ship launching and launching:

The application of marine airbags is less restricted by the site and does not require large-scale machinery and equipment, so it can shorten the engineering cycle,

Save a lot of money. After more than 20 years of development and practice, it has been proved that this product is safe, efficient, green and environmentally friendly.

Features such as mobility and flexibility. Launching ships have developed from flat-bottomed ships weighing tens of tons to large ships with tens of thousands of tons.

Practice has proved that the ship airbag launching and launching process is safe and reliable. At present, this technology has been adopted by the shipbuilding industry,

The port construction industry recognizes that airbag launching technology has been promoted to a certain extent in the United States, Europe, Southeast Asia and other countries.

The production and application of marine airbags are mainly implemented with reference to two industry standards: CB/T3795

Airbags for use", CB/T3837 "Requirements for the upper discharge and launching process of airbags for ships".

2. Lifting and moving of heavy objects:

The use of airbags for heavy lifting and moving is an innovative product with my country’s independent intellectual property rights. It has been widely used at present

Underwater lifting and transportation of heavy objects such as caisson drop ships, transportation of other heavy objects, and underwater installation engineering

3. Floating and salvage:

Marine airbags can generate greater buoyancy and strong load-bearing capacity, and are widely used for rescue of stranded ships and other

Floatation and salvage in areas such as rivers, seas and lakes.

Four: Inner mold for construction

Capsules for hollow slabs of bridge construction Airbags for culvert concrete pouring replace wooden molds and steel molds, saving costs,

Improve efficiency.

Five: pipeline blocking air bag

Plugging airbags for fire fighting pipelines, plugging airbags for oil and gas pipelines, groundwater and gas plugging airbags, isolation airbag

Airbag for closed pipeline in underground construction

Advantages of Henger rubber marine airbag products:

1. High-quality original imported rubber material (Thailand RSS3)

2. Strict and special explosion-proof production process

3. Smooth appearance, physical wear resistance, oil resistance, aging resistance, high acid and alkali resistance

4. Large bearing capacity, good air tightness, high strength, safety and reliability.

5. long lasting

5. Product Advantage

  • 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.

 

  • 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.

  • 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.

  • 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.

  • 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.

 

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

Hydraulic blasting test for Henger marine airbags Inspected by American customer and third-party detection institution

  • 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.

  • 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.

Heavy distortion phenomenon would cause delamination among airbag layers, then to cause more serious accidents.

Such dangerous distortion phenomenon in ship launching process never happened to Henger Marine Airbags
