Changlin ship launching air bag ¡ª how to select air bags? Air bag diameter The air bag diameter is mainly decided by the ship blocks' height. Ship lifting from blocks is the most important stage in the air bag launching process. At this stage, the ship whole weight is to be lifted by air bags, and the air bag working height must be larger than the block height. The air bag diameter should be selected according to the block height. The air bag diameter must be increased by 0.5m-0.7m, which is based on the block height, otherwise the air bag bearing capacity may be not enough. At present air bags with diameter less than 1.2m can only be applied on small ships. Air bags with diameter 1.5m or 1.8m are used to launch over 10, 000dwt ships. For block height larger than 0.9m, diameter 1.5m air bags are mostly chosen for the launching. For block height larger than 1m, diameter 1.8m air bags are preferred. Air bag length For small ships, the air bag length should be slightly larger than the ship molded breadth. Air bag length can be decided by the formula: b

Product Description: Ship launching or upgrading depending on Air Bag is an innovative technology having utmost bright prospect in shipbuilding. Now the Flexible Launching Technology is full of mobility, with advantages such as saving effort, saving time, saving work load, saving investment, flexible, safe, reliable, and outstanding benefit, etc. The technology of apply air gasbag to the launching and landing of ships overcomes the restrictions of traditional slide board technology which is commonly used in building small or medium size ships. After years of practice and accumulation of experience, we have developed this technology from facilitating the launching of only 1, 000 DWT ships to current 55, 000 DWT ships. And now this technology has become into a flexible, promising, secure and mature technology. Besides that, these airbags are widely used in upgrading of ships and boats of all sizes. Construction Features: Launching / Landing Airbags, basic body consists of which consist of our rubber layers, synthetic-cord-reinforced rubber layers, are kind of a cylindrical airbags with hemispherical heads at the both ends. All of these are vulcanized together, and then compress air inside to enable in to roll. 1. Outer Rubber The outer rubber layer that covers the outside of launching airbags 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. Standard color is black. 2. Synthetic-tyre-cord layer for reinforcement The reinforcement cord layers, which are made of Synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly providing strong efficient reinforcement. 3. End Fittings End fittings include air tightness swivel and airbags safety air inlet. Main Application Field of Air-bags: Shipbuilding Industry: Upgrading and launching of ships; Shipwreck salvaging; Ships collision avoidance Hoisting and Moving Industry: Lifting and transporting of heavy weight objects. Building Industry: Pneumatic core moulding use in building industry. Logistics and Warehousing Industry: Gas and Liquid of airbags containers. Airline Industry: Airplane overhaul airbags, fuel tanker and emergency slide way. Marine Industry: Deep sea breeding net cage, offing fence. Emer, gency rescue and disaster relief industry: Fight floods and stop leakage, moving the ruins. Military Affairs industry: Self-saving for field operation vehicles, floating bridge, aquatic pipeline, dropping off oil tanker, naval ships protection. Public Security: Airbags shelter partition for blasting. D1.8m*10m.

Ship Launching Airbags, also known as inflatable marine airbags, roller bags, air lift bags, and salvage bags. Airbags range in size from 0.8 to 4.0m diameter, with effective lengths of 5.0m to 26.0m.. Airbags are used for ship launching, haul-outs, loading, and floating. They are widely used in cargo boat launching and landing, lifting and moving sunken ships, and salvaging stranded boats. Air bags have the benefit of not only saving labor and time, but investment costs. Additionally they are flexible, portable, and dependable, the biggest vessel launched by ship launching airbags up to 100,000 DWT. Ship Launching Airbags are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in long cylindrical balloon shape. Ship launching relying on ship launching airbags is a an extremely promising mature technology, comparing with â??end-on launchingâ?�, â??side ship launchingâ?�, â??float-outâ?�, this ship launching technology overcomes the restrictions of fixed launching track of side-launch. Ship launching airbags are accepted by more and more shipyards world wide.

The history of changlin marine airbags: Air bag launching was developed based on traditional slideway launching mode and invented by chinese in the early ch. C.Environmental friendly In tradational slideway launch, some distance slideway extends into underwater, which affects the flood embankment and navigation environment. Furthermore, lubricating grease mass causes water contamination. Air-bag launch shortens the length of ramp way length under water. There is no emission into water.

Changlin ship launching air bag ¡ª how to select air bags? The type code and specification of air bags should be selected according to ship type, dimensions, and launching extended length at each side should be slightly larger than air bag diameter. For medium ships, the extended length at each end shall not be very long. For example, a normal ship like cargo ship with block coefficient cb > 0.75, airbag should be equal to the breadth of flat bottom at mid-ship (the breadth excludes arc part at bilge). For large ships, if existing airbag length is shorter than the flat bottom breadth, the longest air bags should be ordered. The airbags layout can be interlaced mode or twin-row mode. We would like to provide advice and suggestion according to customer's specific situation. According to customers requirement

Ship docking airbags, basic body consists of rubber layers, synthetic-cord-reinforced rubber layers, are kind of a cylindrical airbags with hemispherical heads at the both ends. All of these are vulcanized together, and then compress air inside to enable in to roll. Material of Docking undocking rubber pontoon launching airbag An airbag is to be constructed of an outer rubber layer, one or more synthetic-tyre-cord layers, and an inner rubber layer. The arrangement of synthetic-tyre-cord reinforcement layers is shown in the picture below, all materials shall be vulcanized firmly. Prior to the airbag production, the outer and inner rubber layers shall be tested to meet criteria in the following table in accordance with the test methods given in the international standard list in the table. While only one satisfactory sample per batch is required for test numbers 1 through 3, all others must be tested for test numbers 4 through 9 annually. If the first sample fails, two additional sample should be tested. If the additional samples pass the test requirements, the materials will be deemed to have passed the test. Otherwise, the materials will be deemed to have failed the test and another batch of materials shall be selected.
