Marine Rubber Airbag

Descripción del producto

Ship Launching Airbags Ship Launching Airbags, also known as roller bags or ship launching balloon, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in long cylindrical balloon shape. Ship launching airbags can be used for the ship launching or ship launching  of tanker, tugboat or barges, carrying vessel, carrier, ferry and other special vessels (AHTS, DSV) and so on. The biggest vessel launched by ship launching airbags up to *5,**0 DWT.
 
Ship launching relying on ship launching airbags is a innovative ship launching technology, comparing with end-on launching, side ship launching, float-out. This ship launching technology overcomes the restrictions of fixed launching track of side-launch. Ship launching airbags are accepted by more more shipyard world wide because of its advantages of saving time, saving investment, flexible, safety.

Construction Features of Ship Launching Airbags

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 head and end mouth. Air tightness swivel and air inlet kits are screwed with end mouth.


 •  Synthetic-tire-cord layer is 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.Evergreen Maritime use the ***0 dtex/2 type synthetic-tire-cord fabric. The warp is over *5 cords per **0 mm in width. 
•  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.
Our properties requirements of outer and inner rubber material comply with ISO ****9.

Classification of Ship Launching Airbags

Ship launching airbags are categorized by ordinary airbags, high-bearing capacity airbags, and Super-high-bearing capacity airbags according to the bearing capacity. We use YT as the type code.

•  YT-QP Ordinary airbags — the air bag with 3, 4 or 5 layers of cord fabric •  YT-QG High-bearing capacity airbags — the air bag with 6, 7 or 8 layers of cord fabric •  YT- QS Super-high-bearing capacity airbags — the air bag with 9, *0 or more layers of cord fabric
The standard diameter of ship launching airbags (D) varies such as 0.8m, 1.0m, 1.2m, 1.5m, 1.8m and 2.0m, etc. The standard effective length of air bag (EL or L) is from 6m to *8m, which should be specified by the user. Other specification ship launching airbags also can be supplied upon request.
