Ship Marine Rubber Airbag 1.5m*20m Concrete Heavy Duty Airbags For Lifting

Maritime Floating Rubber Airbags 1.5m x 20m Heavy Concrete Lifting Airbag

Products introduction
 
Ship air bag launching technology is on the basis of traditional launching technology developed, which USES flexible air bags to replace chute and skateboard,To overcome the many shortcomings of traditional launching.
Outer 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.
Inner Rubber Layer
The inner rubber layer seals pressurized air inside marine airbags.
Synthetic-Tire-Cord Layer as Reinforcement
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
