Product Description
BV CCS Certified Strength Rubber Ship Launching Airbag Marine Salvage Airbags
All Doowin Marine ship launching airbags are manufactured and tested fully compliant with ISO 14409:2011 Ships and marine technology -- Ship launching airbags. To learn more technology, please kindly refer ISO 17682:2013 Ships and marine technology -- Methodology for ship launching utilizing air bags.
Construction of Ship Launching Airbags
Ship launching airbags are constructed with an outer rubber layer, multilayer heavy-duty synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly. These cylindrical balloon bodies feature two conical heads and two end mouths, with airtightness swivel and air inlet kits screwed with end mouth.
Synthetic-tire-cord layer
The reinforcement layer of ship launching airbags consists of rubber-coated synthetic-tire-cord fabrics. Multiple synthetic-tire cord layers are twined at ideal angles using patented "Holistic Wrapping Technology" to maintain internal pressure and distribute stress evenly. We use 1870 dtex/2 type synthetic-tire-cord fabric with warp density exceeding 95 cords per 100mm width and breaking strength over 310N per cord.
Inner and Outer Rubber
Both inner and outer rubber layers undergo rigorous testing to meet international standards before production. The outer rubber layer protects cord layers from abrasion and environmental factors, featuring compounds with exceptional tensile and tear strength for all weather conditions and demanding applications.
Standard ship launching airbag package includes:
- The end of the airbag body
- End flange (Q235 H.D.G)
- Sealing Washer
- Three-direction connector at the inflate end (Q235 H.D.G)
- 3/4′ Ball Valves at the inflate end (Brass)
- Hose connection at the inflate end (Q235)
- High-quality Pressure Gauge
- End plug at the tightness end (Q235 H.D.G)
Classification of Ship Launching Airbags
Ship launching airbags are categorized by bearing capacity per meter length, determined by the number of synthetic-tyre-cord layers which establishes the Safety Working Pressure. Custom configurations are available upon request.
- QP - Ordinary airbag: 3, 4 or 5 layers of cord fabric
- QG - High-bearing capacity: 6, 7, or 8 layers of cord fabric
- QS - Superhigh-bearing capacity: 9, 10, or more layers of cord fabrics
