Dredge ball joint design
The inner diameter of dredge ball joint pipes ranges from 400 mm to 1200 mm. Dredge ball joint liners can be produced from steel and hard iron materials. To allow for variations of the tilting angle, the ball turning angle of a dredge ball joint is 15 degrees to 18 degrees, and the discharge pipe variation for a dredge ball joint ranges from 10 mm to 30 mm. The dredge ball joints are made to operate at low, medium and high pressure.
Dredge ball joint materials
Dredge ball joints can be made from Cast iron of a manganese, chromium, nickel and molybdenum alloy, ductile manganese iron, or hard chromium iron.

We supplies several in-house-designed and patented dredge ball joints with bayonet couplings. The dredge ball joints are typically available for a pressure rating in the range of 10 to 50 bar and for internal pipe-size diameters ranging from 350 to 1100mm.

Classic Ball Joint
The Classic dredge ball joint has proven its worth for over 30 years. It is known for its sturdiness, ease of connecting and simplicity. The design includes one replaceable wear liner in the case. The inside of the ball is protected by the dredge pipe, which runs through the ball.

Crossover Ball Joint
The patented Crossover dredge ball joint includes two replaceable wear liners which provide a streamlined and unrestricted flow area in any tilted position. The optimal flow conditions result in reduced flow resistance and major cost-savings in fuel and wear, which typically result in a very short return on investment.

Greenforce Ball Joint
The Greenforce dredge ball joint is designed for grease-free operation and a working pressure of 40 bar or more. Due to its double ball-design, the forces and weight are reduced considerably. Additionally, the bearing system is completely separated from the dredge flow, allowing installation of a modern grease-free bearing system.
