Foam Filled Fender
The appropriate material should be selected according to the thickness of the inflatable fender during installation. When the thickness of the protective plate reaches meters, the PVC casing should be selected. The anti-slip performance can also effectively reflect the product performance of the protection board. Especially in long lightweight partition walls and exterior walls, due to the small thickness of the product, the anti-lateral movement performance of the product can be effectively guaranteed.
The shell of the floating disc is usually a combination of the two, and the floating disc is mainly composed of the outer lining plate of the valve seat and the hole support bearing. The hole support is mainly composed of a string frame and a traveler. The floating disc is mainly composed of a wire ring and a hole sleeve. The hole sleeve should be complete, flat, no deformation, no damage, flexible bending, and can be made into grooves for screws, nuts, trays and hole sleeves. The tray hole cover should be fixed by screw spot welding or symmetrically installed. The socket and socket are connected to the seamless weld at one time. When the hole sleeve is connected with the diameter of the hole sleeve, flange connection should be used.
Advantages of solid polyurethane floating fenders (marine balls):
1. It has floating performance and is not affected by tidal fluctuations.
2. Bright colors, various colors can be provided according to customer requirements.
3. Compared with the inflatable arc, it does not need to be refilled, is not afraid of scratching, is not afraid of sticking, is not afraid of friction, is resistant to seawater, acid and alkali, and has a service life of 15-30 years. It is safe and maintenance-free.
4. Sturdy, light weight, easy to install and move.
5. When the compression is 60%, the reaction force is obvious from small to large, and the energy absorption is very high.
6 It is suitable for open-air wharfs, gravity-type (dock-type) wharves, wharves with large tidal ranges, and barges of two ships in the open sea.
