D1.5 m x L18m x 6layers Marine Air Bag For Ship Upgrading ,Launching

Ship launching using marine airbags is a very popular vessel launching method. It overcomes the shortcomings of the fixed launching track, which limits the productive capability of the small and medium sized shipyards. Now it has become a Flexible Launching Technology, having the merits of time and labor saving, flexibility, reliability and safety in operation and comprehensive economic benefits etc.

• Saving the investment of shipyard construction
• Simple operation, saving of labor and work hours
• Environment friendly

After years of practice and accumulation of experience, we have developed the technology from launching only 1,000 DWT ships to current 100,000 DWT ships and we will achieve more. And now this technology has become a flexible, promising, secure and mature technology. Besides that, these airbags are widely used in slipping of ships and boats of all sizes.

Why Choose LUHANG Marine Airbags

• 2 or 3-strand cords with great tensile strength

LUHANG Marine airbag production line

We buy raw material natural rubber(from Thailand,Vietnam,Yunnan), carbon black, SBR,etc.Then Mix them as the rates(which can make sure the performance of airbags and fenders),after machine mixing and calendering,then we can see the fabric rubber layer and rubber plate.Now the workers can use them to produce the airbags and fenders. After then,we send the products to the vulcanizer to finished vulcanization.Then we will inflate the products to check the air leakage.If no problem we will packing them to pallets,waiting to ship to u.

Marine Airbag Specification

• The standard specification of marine airbags.

You can choose the required diameter and effective length to meet your projects.

★Diameter (D): from 0.5m to 5.0m.

★Effective Length (EL): from 5m to 30m.

★Total Length (TL): from 6m to 32m

The above specifications only are our standard specifications arrange. Can be supplied customized size upon customers’ request.

• The standard number of layers

The number of layers, which mean the number of Synthetic-tyre-cord layer, usually, our airbags contain 3,4, 5, 6, 7, 8, 9,10 layers types. Other type is still available upon your request to confirm the Safety Working Pressure.
