Qingdao Luhang Inflatable Airbags
Pioneering Marine Operations with Innovation and Reliability
In the realm of shipbuilding and marine engineering, Qingdao Luhang's inflatable airbags have emerged as the preferred choice for global shipyards and marine teams. Also known as roller bags, launching air balloons, inflatable marine airbags, air lift bags, and salvage bags, our products offer safe, efficient, and flexible solutions for vessel launching, landing, salvage, and more.
Innovative Technology: Redefining Traditional Vessel Launching
Qingdao Luhang's inflatable airbags leverage cutting-edge marine airbag launching technology, an innovative approach that overcomes the limitations of traditional "end-on launching," "side launching," and "float-out" methods. By eliminating the need for fixed launching tracks, this flexible technology saves time, reduces investment, and enhances safety, earning recognition from shipyards worldwide.
Continuous Innovation: Our R&D team constantly improves design, materials, and manufacturing processes to ensure flexibility, safety, and reliability.
Proven Applications: Successfully used for launching cargo vessels, barges, chemical tankers, tugboats, AHTS vessels, floating docks, and even construction caissons. The largest vessel launched weighs 100,000 DWT, demonstrating our product's exceptional capability.
Uncompromising Quality: Compliant with Global Standards
All Qingdao Luhang inflatable airbags are manufactured and tested in strict accordance with ISO 14409:2011 (Ships and Marine Technology - Ship Launching Airbags). For technical details, refer to ISO 17682:2013 (Methodology for Ship Launching Utilizing Air Bags).
Advanced Material Construction
Our airbags feature a robust structure of outer rubber layers, multi-layer synthetic tire cord layers, and inner rubber layers, vulcanized to perfection. Additional cord layers reinforce the shoulder ends for superior strength.
1. Synthetic Tire Cord Layers
Reinforcement Core: Made of rubber-coated synthetic tire cord fabrics, layered at ideal angles using our patented "Holistic Wrapping Technology" to evenly distribute stress and withstand internal pressure.
Specifications:
Materials: 1400 dtex/2 or 1400 dtex/3 synthetic tire cord fabric.
Density: Over 95 cords per 100 mm width.
Breaking Strength:
1400 dtex/2: 215 N/cord (vs. ISO 14409: 205 N/cord).
1400 dtex/3: 313 N/cord.
2. Inner and Outer Rubber Layers
Function: The outer layer protects cord layers from abrasion and external forces, while the inner layer ensures airtightness. Both meet rigorous international standards:
| Test Item | Value | Standard |
| Tensile Strength, Mpa | ≥18 | ISO 37 |
| Elongation at Break, % | ≥400 | ISO 37 |
| Hardness, ° (Shore A) | 60±10 | ISO 7619-1 |
| Tear Strength, N/cm | ≥400 | ISO 34-1 |
| Compression Set, % | ≤30 | ISO 815-1 |
| After Thermal Aging | | |
| Holding of Pull Lengthening, % | ≥80 | ISO 188 |
| Holding of Elongation at Break, % | ≥80 | ISO 188 |
| Change of Hardness, ° | ≤8 | ISO 7619-1 |
| Static Ozone Aging | No crack | ISO 1431-1 |
Product Classification and Specifications
Our inflatable airbags are cylindrical with conical ends and air inlet fittings, categorized by bearing capacity into three types:
1. Type & Model
QP (Ordinary): 3-5 cord layers for standard loads.
QG (High-Bearing): 6-8 cord layers for heavy-duty applications.
QS (Superhigh-Bearing): 9+ cord layers for extreme loads.
Example: QG6/1.5x15 = 6 cord layers, 1.5m diameter, 15m length.
2. Standard Specifications
| Parameter | Range (Customizable) |
| Diameter (D) | 0.5–3m |
| Effective Length (EL) | 1–32m |
| Total Length (TL) | 1.2–35m |
| Loading Capacity | 10–40 ton/m |
| End Fittings | Flanges, valves, pressure gauges |
