Details of application

Use ship launching airbags for buoyancy-assisted salvage
Ship launching airbags can generate large buoyancy and strong load-bearing capacity, and have been widely used in the rescue of stranded ships and other fields of floatation and salvage. It is a good protection device, and the ship launching airbag will play a great role as an important tool in an emergency.

The ship uses the marine launching airbag to discharge and launch
The ship uses the marine launching airbag as the main tool, supports the ship on the marine launching airbag, and moves it from the repair site into the water area or from the water area to the shore, using the low inflation pressure of the ship launching airbag, The large bearing area and the characteristics of easy rolling after large deformation, the ship is first lifted from the pier and placed on the ship launching airbag, and then pulled by the steel cable and the rolling of the ship launching airbag, so that the ship slowly slides into the water.

Product brief introduction

Product Description

We Are The Expert In Marine Airbag And Fender

Marine air bag is widely used in shipping launching and docking in shipyards, specially small and medium shipyards along riverside and seaside in American and Asia countries. Marine airbag is also called shipping launching airbag that indicates the most popular application of airbag is for shipping launching. It is estimated more than 80% new built ships whose WDT is below 60000 are launching by marine airbags.

This flexible launching technology is highly versatile and helps companies in the building and marine industry saving effort, time, work load and investment.

Structure

The airbag body is constructed of an inner rubber layer, reinforced cord layers and an outer rubber layer. All of these layers are vulcanized together.
The outer skin rubber compound is designed and manufactured to be able to withstand both strenuous use including abrasion during adverse weather conditions whilst protecting the cord layers and inner rubber.
The synthetic cord layers are arranged and designed to evenly distribute loads and stresses, thus maintaining the fender'sinternal air pressure.
The inner rubber layer seals pressurized air inside marine airbags.

Qingdao Luhang using nature rubber and nylon cord as raw material synthetic cord layer is made of rubber and synthetic tyre cord fabric.

Material And Accessory

Our company has 30 years of experience in rubber formulators and has a unique airbag rubber formula. We will adjust the formula according to the season and humidity. For example, in summer, the specific gravity of materials such as carbon black will be increased to maintain the hardness and wear resistance of the airbag. A rubber performance inspection will be conducted after each adjustment to the formula, and a rubber performance inspection will be conducted every seven days when the formula remains unchanged. Other manufacturers' formulas are prone to adulteration with recycled rubber. Our company promises never to use recycled rubber; all use natural rubber, butadiene rubber, and styrene-butadiene rubber with excellent performance.
