Do you know about Dredge Ball Joints?
Dredge ball joint is a connection between two pipes that are used to transport a mixture of water and sand from a dredge to the discharging area. Its tilting angle is from 15 degrees to 20 degrees, and can provide a flexible load-bearing connection between sections of a pipeline.
There are various pressure levels, such as 10, 20, 30bar. It is capable of transmitting high loads from one section to another. The principle field of application is in floating lines, whose sections are supported by pontoons or other buoyancy, and the ball joints are usually used for dredging and mining industries.
The advantages of dredger ball joints from Nanjing Deers:
- More anti-corrosive and anti-wear
- Pinch type connection with heavy duty clamps
- Easy lock mechanism
- Robust structure designed to operate in harsh environments
- More life time and lower downtime
- Angle from 15 degree to 20 degree is available
- Working pressure from 10 to 30bar is available
The dredge ball joints have a welded connection to the dredge pipe or, optionally, a flanged connection. The specifications are as follows：
