Navigation Buoy
Shandong Buoy&Pipe Industry Co.,Ltd is a high-tech incorporated company which is researching and manufacturing UHMWPE products. We are the only one to apply UHMWPE material in production of marine equipment like navigation buoy,light beacon,etc.
UHMWPE is the best substitution material of carbon steel and stainless steel. With the superior properties---higher impact resistance,ESCR,creep resistance in high temperature,lower friction coefficient,good self lubrication,higher environmental protection,etc.UHMWPE buoy is used widely recent years.
Comparisons of Different Buoys:
Item | UHMWPE Single Body Buoy | Plastic Split Combinded Buoy | Steel Welded Buoy |
Material | High strength plastic—UHMWPE | Common Plastic, e.g Polyethylene | Steel |
Structure Performance | Single body, high density PU foam filled, steel frame inside | Combinded body, no polyurethane foam, no steel frame | Single body, no polyurethane foam |
Maintenance | No need paint and water growth cleaning for the tail pipe and buoy body. | Need paint 1 time, water growth cleaning 1 time per year | Need paint 1 time, water growth cleaning 1 time per year |
Deployment | Small vessels
| Small vessels | Large vessels |
Environmental Protection | No pollution | Need painting for tail pipe and light stand, pollute environment | Need painting for the whole buoy, pollute environment |
Service Life | 50 years
| 10 years
| 5 years |
Impact resistance | Higher resilience, no deformation, no damaging, no leaking, no leaning, and no sinking, maintenancefree, continual use available | Leaking, leaning, and sinking occurred once impacted, the buoy could not work again. | Leaking, leaning, sinking, and damaging vessels occurred once impacted, the buoy could not work again. |
