Natural Rubber Marine Inflatable Roller Ship Launching Marine Airbag

Product Specification

Marine Inflatable Roller Ship Launching Marine Airbag

Introduction
 

Marine Rubber Airbag 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 environmental protection.

Features

1. Long lifespan

2. Movable and reusable

3. Saving investment costs

4. Saving labor and time

Application

• 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.

• Weight Lifting & Moving

Marine rubber fend could be applied to caisson lifting, launching, moving and transporting in port constructing projects

• 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.

Storage

 
1. When we don’t use the marine airbag roller for a long time, it should be washed and dried. Should sue the external talcum powder on the lifting airbag surface. Should put the airbag in a dry, ventilated room away from the light source. Keep away the shipping airbags safe to avoid stretching, compression and deformation.
2. Keep the airbag away from heat sources.
3. Can not contact the airbags launching to acids, alkalis, greases and organic solvents.
 

Test

 
1. Air tightness test
Fill the air into the pneumatic lifting bags to a certain internal test pressure without any load. After one hour, measure the internal pressure again. By comparing with two times’ data, the pressure loss should be less than 5%.
 
2. Performance test
Without any load, fill the air into the airbag balloon by the airbag standard data form or by clients’ requirement.
We will do the strictly inspection before the delivery for the outer appearance and the air loose test. If it is unqualified, can not release definitely.
 
3. Blasting test
This test should give the minimum burst pressure value of the airbag, as listed in the airbag performance table burst pressure. In order to be safe, since the airbag belongs to the pressure vessel, it is necessary to use a water flushing while filling the airbag until the airbag bursts. The water pressure during airbag blasting should be larger than or equal to the values listed in the standard performance table.
 
4. Compression-recovery Test
In order to verify the recoverability of the airbag, the airbag should be repeatedly and rapidly compressed and released in a short time. Due to the limitation of the airbag length and the limitation of the compression recovery equipment, the compression recovery test can be reduced by the same number of layers. The airbag is inflated to make the internal pressure reach the pressure of the airbag performance data. And the airbag is vertically compressed until the compression deformation reaches 75%. Keep this state for 1 minute. The pressure is then released and the balloon diameter should be restored to more than 97% of its original diameter within 5 minutes.
