Ship Launching Black Marine Air Bag 2.0*20m Inflatable Rubber Balloons

Products introduction

LuHang ship launching airbag is specially designed for launching technology development, the main function is carrying or pulling the ship launching uphill, has a very high load capacity, wear resistance and corrosion resistance to seawater.
 
1 . The Uuter Rubber Layer
The outer rubber layer that covers the outside of marine airbag to protect under layers from abrasion and other external forces. This compound has sufficient tensile and tearing strength to withstand any condition and hard usage.
 
2 . The Inner Rubber Layer
The inner rubber layer seals pressurized air inside marine airbags.

3 . The Synthetic-Tire-Cord Layer 

The reinforcement cord layers, which are made of synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and distribute stress evenly. So they can provide strong efficient reinforcement.
 

Performance Calculation Principle of Airbags

The bearing capacity of marine airbags 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 marine airbag 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 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
