Rubber Ship Airbags / Salvage Marine Airbag for Ship Launching / Upgrading
Ship launching rubber airbags technique was found to be versatile and flexible in marine engineering fields. Rubber Airbags can lift up heavy like jacks and move it forward,act as pneumatic rollers. Airbags can roll over pits and knuckles, so they have less demands of the ground or ramp. Different from rigid trolleys, launching airbags can be compressed at different ratio, thus they can absorb the impact energy emerges in some structure launching projects.
NANHAI AIRBAG Management system is ISO9001: 2000 certified and complys with all demands of the ISO 14409: 2011 standard ( For ship launching airbags) during manufacturing procedure . NANHAI AIRBAG guarantees excellent quality and performances of all products. Customer requirements are strictly followed during all production phases. His quality control department performs a true procedure control of the material and products.
Marine rubber airbags will provide you with a unique capability of land transport very large vessels, heavy loads or heavy construction over ground where terrain would otherwise prevent such an operation. The NANHAI AIRBAG have wide marine rubbr airbags in capacities from 70 tons to 380 tons per bag. NANHAI AIRBAG also has a selection of bags with diameters up to 2m in diameter and up to 20m in length to cover virtually all applications.
Inflatable Floating Marine Rubber Airbags infomation
Marine airbags are widely used for ship launching, heavy transportation and marine salvage nowadays. Marine airbags are often called ship launching airbags that indicate the most popular application of these heavy duty airbags is for ship launching. It is estimated that more than 80 percent new built ships who’s DWT below 60,000 are launched by marine airbags.
Marine airbags are found to be powerful and versatile tools for many other marine projects such as disembarking ships, heavy transportation, re-floating salvage etc. But how to select suitable marine airbags for a specific project? Let us see suggestions from a professional marine airbags manufacturer and engineering company.
Ship Launching Rubber Airbags Structure
Reference for marine airbag selection
There are two industrial standards for marine airbags in China.: one is product standard named "Air bag for ship up to or down to launching way "; another is technology standard named "Technological Requirements for ship Upgrading or Launching Relying on Air-bags".The latter offer the basic calculation of marine airbags employed in a marine project.
According to Chinese industrial standards people will know the approximate quantity and specifications of marine airbags needed for their projects then consult the manufacturer to confirm the design. There maybe optional specifications to be selected for a specific marine project and a good manufacturer should know the best choice. The data of marine airbags' blasting pressure will reveal the product's quality level. For top quality marine airbags, such as one 1.5 m diameter and 7 m length Evergreen marine airbag, the blasting pressure is 0.67 Mpa which indicates the safe coefficient is more than 5 considering its 0.12Mpa working pressure.
Full technical service is the qualification of a good company. Although general calculation formula or performance data of marine airbags can be got from most factories but detailed calculations based on mathematic model and experience is more important to the success of marine projects.
In a word
Good selection of marine airbags is vital for the success of marine projects. Get basic knowledge of marine airbags selection then consult with manufacturers can help people complete projects in shortest time.
