Pneumatic Marine Parts Underwater Air Lifting Bags for Ship Landing and Launching

Product Description

Pneumatic Marine parts underwater air lifting bags for Ship Landing and Launching
1.Product Introduction
ship launching and landing Marine rubber lifting airbag also known as rubber airbag, ship launching airbag, ship salvage airbag, inflatable airbag, ship lifting bag, air balloon, made by rubber & multi-layer of rubber-dipped tyre fabric.
ship launching and landing Marine rubber lifting airbag meet the CB/T3837 and CB/T 3795 requirements
ship launching and landing Marine rubber lifting airbag 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.
marine laucing airbags characteristics:
1.High strength:The polyamide cord thread for airbag is produced with high tension reinforced fiber.A cord thread has the strength more than 320N, and the cord fabric has consistent and reliable quality.Our company developed and manufactured high strength airbags with the higher strength steel wires and aramid fiber as skeleton materials on customers' request.
2.Wear resistance and anti-aging:An pneumatic airbags often works in extreme conditions, for example, it is soaked in sea water, insolated in the direct sunlight and rolled in sand.Our marine is produced with natural rubber in a reasonable formula.The practice proves that airbag has high wear resistance and anti-aging ability, and the service life as long as 8-10 years.
3.Good air tightness:Our Company pneumatic airbags use high quality rubber, as material and the advanced manufacture process to assure that our products have good air tightness, especially air tightness of the assisted floated airbag.Our airbag can keep its pressure 24 hours with work pressure, the pressure will reduce less than 3%.
4.Safety and reliability:Giyo marine airbag with the optimized structure design has the safety coefficient of 4-6 times, namely that its bursting pressure is 4-6 times its work pressure.Our airbag has a multi-channel airbag mouth to enhance the strength and air tightness between the airbag body and mouth.
