HI-SEA drag head is of a modern short and wide design to optimize flow and efficiency. The latest CFD software has been used to optimize the flow patterns of the transported sand and water mixture within the drag head. Cutting teeth and jet water nozzles have been placed at an optimal position boosting the erosion of soil. The jetwater-assisted drag head follows the uneven bottom profile and maximizes the mixture concentration.
The pipe diameter from 420mm to 1200mm, HI-SEA drag heads can be customized to the client’s specific requirements and OEM,and receive the third party inspection and certification, such as LR,BV,DNV.
