An Inside Look At The Materials And Engineering Behind Modern Marine Airbags

April 16, 2025

The Advanced Materials and Precision Engineering Powering Today’s Airbag Technology

Ship Launching Airbags, Known As Roller Bags Or Ship Launching Balloons, Are Made Of Heavy-Duty Synthetic-Tire-Cord Layers With Inner And Out Rubber Layers In A Long Cylindrical Balloon Shape. Ship Launching Airbags Can Be Used For Ship Launching, Ship Landing Work.

Ship Launching Or Upgrading Using Marine Airbags Is An Innovative Ship Launching Technology. It Overcomes The Disadvantage Of "End-On Launching", "Side Ship Launching", "Float-Out". This Ship Launching Technology Overcomes The Restrictions Of The Fixed Launching Track Of Side-Launch.

Hongruntong Marine Airbags

Hongruntong Launching Airbags Can Be Adapted To Different Vessel Types And Support The Launching Of Vessels Up To 100,000dwt. The Airbags Are Designed And Manufactured In Accordance With Iso 14409:2011 Standard.

Synthetic Tire Cord Layer

The Reinforcing Layer Of The Ship Launching Airbag Consists Of Rubber-Coated Synthetic Tire Cord Fabric. A Unique “Monolithic Winding Technology” Is Used To Wind Multiple Layers Of Synthetic Cord At An Ideal Angle. This Technique Ensures That The Airbag Distributes Stresses Evenly And Maintains A Stable Internal Pressure. We Use 1400 Dtex/2 Or 1400 Dtex/3 Synthetic Cord Fabrics With A Breaking Strength Of Up To 310 N, Which Far Exceeds The Breaking Strength Of 205 N Required By Iso 14409.

Inner and outer rubber layers

The Outer Rubber Layer Is Designed To Resist Abrasion And Is Characterized By Tear And Stretch Resistance, Enabling It To Cope With Extreme Environmental Conditions. The Inner Rubber Layer Guarantees The Sealing Of The Airbag, Ensuring That The Gas Does Not Leak, Further Improving The Reliability Of The Airbag.

Classification Of Marine Airbags

Our Boat Marine Airbags Feature An Advanced Cylindrical Design With Two Strong Tapered Heads And Tailports. The Tail Port Design Is A Screw-In Construction With A Swivel Ring And Inlet Kit. This Configuration Allows For A High Degree Of Stability During Inflation And Deflation.

Structural design

The Airbag Is Designed Using High Pressure Resistant Synthetic Materials. The Overall Structure Includes The Airbag Body, End Fittings, And Airbag Inflation System. Each Part Is Rigorously Tested To Ensure A High Degree Of Safety And Reliability.

Rubber airbag specifications

The Standard Specifications Of Rubber Airbags Can Be Flexibly Customized According To Project Requirements. Common Diameters Range From 0.5 Meters To 3 Meters, And Effective Lengths From 1 Meter To 32 Meters, With A Maximum Of 35 Meters. Load Capacity Can Be Selected As Required, Usually From 10 Tons To 40 Tons Per Meter. You Can Choose The Right Specification According To The Demand. Special Requirements Can Be Customized To Meet The Unique Requirements Of The Project By Customizing The Airbag Parameters To Specific Conditions.
