DooFlex Totally Enclosed Type Air Lifting Bags (Salvage Tube, Inflatable Buoyancy Bags) is one kind effective alternative of Open Bottom Parachute type lifting bags for the surface buoyancy support operation.
Totally Enclosed Type Air Lifting Bags can be used for buoyancy support and refloatation operation in shallow water and on the surface, support/salvage pontoons for bridges, floating platforms, dock gates, sunkend objects or military equipment. Totally enclosed lifting bags offer an effectual method of reducing the draught of vessel and floating underwater structures. Then also provide an ideal system of buoyancy for cable and static buoyancy support.
DooFlex Totally Enclosed Type air lifting bags are cylindrical shaped units, fabricated from heavy duty polyester cloth coated with P. V. C (Made in Germany), completely equipped including the appropriate quantity of automatic air relief valves, certified heavy duty polyester webbing with shackles (with safe working factor 6: 1), and air inlet stainless/brass ball valves.
Application of Air Lifting Bags:
- Suitable for shallow water usage
- Suitable for long term use
- Military equipment
- Bridge supports
- Pontoons
- Marine salvage and refloatation
- Extra buoyancy for pipe and cable float out operations
Quality Assurance Guaranteed
All Dooflex air lift bags are manufactured and tested comply with IMCA D016, Rev3-June 2007 Guidelines. Quality is approved by SGS & UKAS in accordance with ISO9001: 2008.
Unisite to be your best Casting Parts supplier. Our foundry is capable to make carbon steel alloys out of many casting processes per your request. Specifically, Carbon Steel Sand Casting is the most economical way to make the part. However, the surface roughness will not be very good. If you want the relative big part with good surface finish, Water glass process is your best option. Besides, silica sol investment casting process will be your best choice if you want to get the good finish part. It all depends on your requirements and budget range. Our main products with carbon steel alloys include tractors, trucks, forklifts, excavator, pump, valve, Construction machinery, trains, and marine boats.
Carbon steel is among one of main materials in the world of steel castings. Carbon steels can be classified into below types according to their carbon content:
Low-carbon steels(< 0.20% C): Offer a range of tensile properties via heat treatment and can be hardened to give high surface hardness with abrasion resistance and good core ductility.
Medium-carbon steels(0.20 to 0.50% C): This composition allows it to be more durable, pliable, and stronger. A range of tensile strengths are possible with good ductility and shock resistance, readily machined in the softened condition.
High-carbon steels(> 0.50% C): Strong and has a good shape memory, making it a particularly useful option for spring manufacturers. This alloy steel for high tensile applications is subject to wear and abrasion and is suitable for heavy-duty applications as well.
