Product advantages
The possibility of air leakage in the joint area of metal part and rubber part is also increasing as working pressure of airbag is added. After using for times under high working pressure, the airbag would burst and metal part would hurt workers.
Henger invented new anti-explosion design of the airbag end part, increasing the bonding strength and air tightness between rubber body part and end metal part. Henger airbag is working very well under higher working pressure without potential safety hazard.
Inflatable rubber airbag’s main technical requirement is regulated in CB/T 3795--1996 published by China State Shipbuilding Corporation.
Henger adopts new rubber formula and high-strength enhanced synthetic-tyre-cord layer, which improves the airbag’s bearing capacity two times more than CB/T 3795--1996 standard.
The synthetic-tyre-cord layer of Henger marine airbag adopts dipped Nylon-6 1400dtex/3-V2 tyre cord.
The strength & durability of airbag improves 20%, compared to polyester tire cord which is widely used by friendly competitors.
With more than 20 years development in China, marine rubber airbag is proved to be the most reliable and stable technique for ship launching & upgrading. It is applicable from tons of flat board to ten thousand tons of huge ship. Meanwhile, marine rubber airbag is also widely acknowledged by foreign dockyards, shipyards, port/harbour construction companies. Ship launching & upgrading technique with marine rubber airbag is also highly promoted in the markets, such as America, Europe, Southeast Asia.
Marine rubber fend could be applied to caisson lifting, launching, moving and transporting in port constructing projects
Because marine rubber airbag has buoyancy force and load-bearing capacity, it is also widely used in sunken vessel salvage and Buoyancy Aid.
FAQ ABOUT MARINE RUBBER AIRBAGS
1."Can I use marine rubber airbags for both ship launching and
docking ?"
Answer: Yes, our rubber airbags are widely used for ship launching/
docking/ lifting/ moving and salvage etc.now.
2. "What's the advantage of your marine rubber airbags compared to
slipway ?"
Answer:
1) our marine rubber airbags are much cheaper than slipway,but also
reusable, it can save money and labor
2) our marine rubber airbags are moveable , it can save time and
more flexible
3) our rubber airbags are much soft than slipway,there's no harm to
the bottom of the ship.
