Performance Calculation Principle of Airbags

The bearing capacity of ship launching rubber air bags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.Because of the flexibility of rubebr air bag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of rubber airbags will vary as well as the contact area.

The approximate bearing capacity can be calculated as follows:

F=PS
S=π x (D1-D2)/2

Mark:
F: Bearing capacity

P: Inner pressure

S: Contact area

D1: Diameter of airbags when free of loat

D2: Working height of airbags when loaded

Specification:

Initially established as Qingdao Luhang Marine Airbag Factory in 1988 and changed to Qingdao Luhang Marine Airbags and Fenders Co.,Ltd in 2011, Qingdao Luhang had been devoted itself to developing and manufacturing marine airbags and marine fenders for more than 2 decades.

The factory area is 56,000m² with building area of  21,000m². The company has registered capital of USD 3 million and fixed asset of USD1.2 billion. We have a full line of production equipment: rubber mixing machine, rubber roller machine, the China biggest vulcanization tanks, the biggest Press Inspection Machine, EVA foam processing machine, Foam shaping machines and SPUA spraying machine.

Through these years' development, we have full range of marine airbags and marine fenders:

Ship Launching Airbags for ship launching and docking in shipyards

Marine Salvage Airbags for salvaging sinked vessels or refloating objects from under water

Other Airbags for special usage

Pneumatic Rubber Marine Fenders for ships and docks berthing

Foam Filled Marine Fenders for ship and docks berthing

Fixed Dock Rubber Fenders for docks and wharfs

Marine Buoys

From the begginning we have been focusing on technological innovation. With a team of experienced technicans and engineers, we have developed some high tech marine products and got some petents. We have been approved as a supplier of Navy products. 

Quality is our life line. We provide service of “three guarantees” (returning, repairing and replacing) on all our products in case of any defects due to the problems of material,manufacturing, performance under conditions of normal operation and maintenance.
