2 Simple Things We Need to Know About Ship Launching Airbags

Ship launching airbags are known as roller bags, launching air balloons, inflatable marine airbags, air lift bags, and salvage bags. Ship launching airbags are specialized marine rubber air bags that are used for launching marine vessels. ship landing or haul-outs. Marine rubber airbags are also widely used in loading, floating, lifting and moving sunken ships, and salvaging stranded boats. Rubber airbags are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in a long cylindrical balloon shape.

Rubber airbags are constructed of an out rubber layer, multi-layer synthetic-tire-cord layers, and inner rubber layer vulcanized firmly. 

Rubber airbags are cylindrical balloon body, with two conical head and end mouth. Swivels and air inlet kits are screwed with end mouth.

Inner and Outer Rubber

Prior to the air bag 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. Can check with airbag structure.

Synthetic-tire-cord layer

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. 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.
