Suction Pipes

Suction pipes fulfill a number of key functions in the dredging process. They ensure full control of the draghead on the bottom, transport the dredge mixture to the hopper, transmit the trailing force from the draghead to the ship and support pipes and cabling.

Standard

IHC Parts & Services supplies standardised two-part suction pipes for installation on hopper dredgers with internal diameters from 350 to 1200mm. Hinged construction together with swell compensation contributes to an ideal contact of the draghead with the bottom.

installations assembled to a drag load of 4000 kN,
submerged dredge pump (up to 10,000 kW) in upper or lower pipe,
