Dredge Yard has delivered dredge ball joints to Saudi Arabia. The ball joints delivered to S.A. are designed and manufactured by Dredge Yard.
The ball joints are capable of achieving working pressure of 20 bar and discharge pipe diameter of 650mm. Wear resistant liner is assembled so as to increase the life time of the ball joint. A rubber seal is provided to make the ball joint water tight during pressure. Both of them, the case liner and the rubber seal, are considered wear parts but they can be easily renewed.
These types of ball joints have a 15-degree tilting angle to all directions. The grease grooves are provided in the stiffened gland to reduce corrosion and the friction between the gland and the ball. The ball joint is provided with one locking pin to prevent the gland from any sliding movement during operation.
The ball joints will be used for transport of sand, gravel and stones from the Cutter Suction Dredger.
