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
Ship launching airbags are to be constructed of an out rubber layer, multilayer heavy-duty synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly. Ship launching airbags are cylindrical balloon body, with two conical heads and two end mouths. Airtightness swivel and air inlet kits are screwed with end mouth.
Synthetic-tire-cord layer
The Synthetic-tire-cord layer is the reinforcement layer of the ship launching airbags which are made of rubber-coated synthetic-tire-cord fabrics. Many synthetic-tire cord layers are twined at ideal angles by unique and patented “Holistic Wrapping Technology“. To hold the internal pressure and to distribute the stress evenly. We use the 1870 dtex/2 type synthetic-tire-cord fabric. The warp is over 95 cords per 100 mm in width. The breaking strength is more than 310 N per cords.
Inner and Outer Rubber
Prior to the airbag production, the outer and inner rubber layers shall be tested to meet the criteria in accordance with the test methods given in the International Standards listed below. The outer rubber layer covers the outside of ship launching airbags. To protects the cord layers from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage.
The standard ship launching airbags include the below spares. Ready for use.
Ship Launching air bags are categorized by the following three types according to the bearing capacity, per meter in length. We define the number of layers, which means the number of Synthetic-tyre-cord layers, in order to confirm the Safety Working Pressure. Another type is available upon clients’ request.
