Production Name :

China Supplier Culvert formwork and bridge component (Rubber formwork) Inflatable mandrel

Marine airbag also known as rubber airbag, ship air bags, ship launching airbag, ship salvage airbag, boat salvage airbags, inflatable airbag, ship lifting bag, air balloon, made by rubber & multi layer of rubber-dipped tyre fabric. Airbags are widely used in launching and landing ship/ boat/vessel, lifting and moving heavy goods, salvaging stranded boats. Marine airbags are very popular with shipyard, ship owner, and marine supplies company now.

1- Design scientific and reasonable used inflatable rubber mandrel, or casting parts, finished product can meet the requirement of design, easy operation, save work, save time, save material.
2- Have good ageing resistance performance and long service life this product use synthetic rubber, natural rubber and strengthen layer vulcanize. Has very good resistance to bulge, flexibility and elasticity, so can satisfy all sorts of work in the conditions of use.
3- Widely applicable temperature , within the scope 10 °C ~ +90 °C of the material without change.

4- For building light-duty construction provides favorable conditions to stress hollow concrete component, due to the rubber mandrel, the weight than use stress solid component light 20%, so it can reducing the weight of the upper structure of building, can make the pile foundation short, increase span, make the construction become simple and safety.
5- Construction technology is simple, safe, health, use it only need a few simple tools, without special process. Only put the mandrel into negative reinforcement cage, inflate air to achieve work pressure, then pouring the concrete. When the concrete freezing, put gas out mandrel , in thus complete the product component forming, and it not pollute the environment.
