DN850 Dredging Ball Joint

The DN850 Dredging Ball Joint is a key component used in dredging operations, especially in the connection of dredging pipes, for transporting excavated sediment and other materials. The DN850 designation indicates a pipeline with an 850 mm diameter, suitable for medium to large-scale dredging projects. The ball joint must be capable of handling the high volumes and pressures associated with such operations.

Feature:

Low maintenance cost

Replaceable liners made from wear resistant materials

Corrosion, wave and wind resistant

Good sealing performance, no leakage

High flexibility and reliability

Overview

The DN850 ball joint can typically rotate and tilt, providing up to 15 degrees or more of movement. This flexibility reduces the risk of damage to the pipeline due to shifting sea conditions or vessel movements.

Dredge ball joints type:

1. Tilting angle of 15 degrees: 10bar, 20bar and 30bar.

2. Tilting angle of 18 degrees: 10bar, 20bar and 30bar.

Materials:

CASE: ZG30Mn GLAND: ZG30Mn BALL: ZG30Mn

LINER: ZG30Mn or 30CrMoNi SEAL: NBR LOCK: Q345 or Q235
