Floating Dredging Hole
Since the floating mud hose is usually used in bad conditions and poor environment, the product
must have a reliable use of performance and safety features. Working condition asked not to be
dependent on some other floating-body support surface, low center of gravity, good stability,
corrosion resistance, impact resistance, bending resistant, suitable for high surge areas or narrow
waters, long service life.

 Non-self-floating dredging hose
The non-self-floating dredging hose is installed between steel
pipes of the mud pipelines which can increase the flexibility and
the bending resistance for mud pipelines. The product has
reasonable structure, reliable work pressure and it’s easy to
install, which is widely used in harbor dredging, basic hydraulic
fill, port building and water project construction.
