Inflatable Marine Equipment 9 Layers High Air Tightness Ship Launching Rubber Airbags
Florescence has its own factory which manufactures rubber products for over 25 years. Equipped with advanced manufacture, test and R&D equipments, our company becomes a Chinese leading marine rubber airbags with the rich experience, rapid development, most abundant capital & technology and the most competitive products.
Description:
Ship Rubber Airbags, basic body consists of rubber layers, synthetic-cord-reinforced rubber layers, are kind of a cylindrical airbags with hemispherical heads at the both ends. All of these are vulcanized together, and then compress air inside to enable in to roll.
An airbag is to be constructed of an outer rubber layer, one or more synthetic-tyre-cord layers, and an inner rubber layer. The arrangement of synthetic-tyre-cord reinforcement layers is shown in the picture below, all materials shall be vulcanized firmly.
Specification:
| Diameter | 0.5-2.8m |
| Length | 5-26m |
| Cord Layers | 3-12 layers |
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 airbags 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.
Structure of the Florescence Ship Rubber Airbag
1. Airbag body
The airbagbody is composed by natural rubber and strength fiber material through vulcanization progressing
2. Terminal iron part
The terminal iron part is made of cast iron, it is combined closely with the airbag body, one end is for pulling when you move it, and the other end if for charging and discharging the air.
The outer rubber layers can protect the cord layers from abrasion and other external forces. The airbags have sufficient tensile and tear strength to withstand strict weather and situation.
Advantage:
- High precision engineering using 3-strand cords with great tensile strength.
- Made from NEW industry leading quality rubber.
- Assurance of true number of layers.
- High-performance quality and above-industry-standard layer thickness.
Precautions of FLORESCENCE Ship Rubber Airbag
1. Over pressure Control:
Strictly control the operating pressure, over pressure is forbidden.
2. The Landing Slipway Requirements:
The landing ground should be ground or cement concrete, according the tonnage of different ships.
3. Avoid Sharp Objects:
Make sure no sharp objects and smooth & clean ground during using airbags in case of any break.
4. Avoid Distortion And Overweight:
Avoid distortion in the length direction during rolling and avoid overweight load after gas charging.
◆The above data may vary a little bit under the different situation. But it will not affect the performance of the Rubber Airbag.
◆We can customize many different airbags sizes in basis of clients' requirements. And the more cord layers you choose , you will get the longer usage time and better performance of the rubber airbag.
How to launch ship by marine airbag
Step1: Prepare the launching slipway and related workers. As per calculation, select and check the appropriate marine airbags and quantity. Tidy up the launching slipway. Fix the ship by winch and anchors. Prepare all the necessary equipments.
Step2: Taking out all standing blocks under stern and middle one by one, and put in airbags. The distance between two rows should be confirmed as per the calculation.
Step3: Taking out all standing blocks under the prow. Run the winch and release the cable. Let the ship launch to water.
Step4: After launching, check all the deckhouse to confirm if there is any problem. Meanwhile, retrieving all the airbags.
