Latest company case about Vietnam Dredging Contractor Finds Corrosion-Resistant Solution for Wet Excavation
Background:

A Vietnamese contractor is involved in dredging and widening irrigation canals in the Mekong Delta region, using long-reach excavators.

Challenge:

Underwater excavation presents two problems: high abrasion from sand and silt, and corrosion from constant water exposure. Standard teeth were rusting and wearing out simultaneously.

Solution:

While our standard teeth have good base material properties, we ensured this shipment received a slightly modified surface treatment optimized for abrasive wet conditions.

Result:

The teeth showed excellent resistance to both sand abrasion and water corrosion. The client reported that a single set of teeth lasted for the entire duration of a 2-month canal dredging phase, a significant improvement over their previous supplier.
