Marine rubber Boat balloon airbag
---Evergreen Maritime, 15 years manufacturer..
1.Usage of Marine Airbags
Ship Launching Marine Airbags, also known as roller bags or ship launching rubber balloon, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in long cylindrical balloon shape. Marine Airbags for Ship Launching and Dry Docking for barge can be used for n Brazil, Indonesia Shipyard especially for barges launching, pull to shore, vessels' haul out and ship landing work.
2.Comparison with other Launch Way
Rollers Bag 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 and more shipyards world wide due to its advantages of saving time, saving investment, flexible, safety. The biggest vessel launched by ship launching airbags up to 100,000 DWT.
3.Material and constructure of Marine Airbag
Inflatable Marine 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 marine airbags are cylindrical balloon body, with two conical head and end mouth. Air tightness swivel and air inlet kits are screwed with end mouth. Refer below picture.
1. End cap/plug at the tightness end ( Q235 H.D.G or Stainless Steel )
2. Rubber Pad at two ends( to strength the tightness)
3. End protective clip at two ends ( Q235 H.D.G or stainless steel )
4. Marine Airbags Body
5. Safety Air inflate at one end and Air Tightness Swivel at the other end ( Q235 H.D.G or stainless steel)
6. Three-direct-link at the inflate end( Q235 H.D.G. Or stainless Steel)
7. 3/4' ball valve (brass)
8. Hose connection at the inflate end (Q235 H.D.G or stainless steel)
9. High quality Pressure Gauge at the inflate end.
4.Classification of Roller Marine Air Bags
Ship launching marine airbags are categorized by "ordinary airbags", "high-bearing capacity airbags", and "Super-high-bearing capacity airbags" according to the bearing capacity.
- QP Ordinary airbags - the air bag with 3, 4 or 5 layers of cord fabric
- QG High-bearing capacity airbags - the air bag with 6, 7 or 8 layers of cord fabric
- QS Super-high-bearing capacity airbags - the air bag with 9, 10 or more layers of cord
