The new 30,000m³ dredger’s main hull was recently completed by Shanghai Zhenhua Port Machinery (Group) Co.(ZPMC)! This powerful vessel handles not only regular port dredging but also deep-sea operations like sand mining and ultra-long-distance subsea pipeline work. It's China's first ultra-large dredger of this class, boosting the nation’s global competitiveness in advanced dredging.

Leveraging 20 years of materials expertise, Wodon equips this "super-digging, super-strong, super-long-discharging" dredger with its own wear-resistant pipes. From ports to deep oceans, Wodon pipes handle extreme conditions with extraordinary properties, contributing to China’s development of dredging equipment.

Complete Wear Protection for All Applications: Ports to Deep Sea
Wodon wear resistant pipes solve three critical dredging challenges:

General Port Dredging
Conventional pipes rapidly deteriorate from sand and gravel abrasion. Wodon's proprietary dual-metal overlay welded pipes significantly extend service life even under harsh mixed abrasion from coral and volcanic rock during deep-sea sand mining. This reduces maintenance downtime caused by wear damage.

Deep-Sea Sand Mining
High-velocity sand causes pipe fractures during long-distance pumping. Wodon's triple-layer system features wear resistant surface overlay, flexible energy-absorbing interlayer and high-strength structural base. This integrated design resists abrasion while dissipating impact energy, preventing brittle fractures common in single-layer pipes and ensuring stable operation under complex pressure conditions.

Subsea Pipeline Operations
Facing the altwater corrosion from chloride ions, Wodon uses specialized corrosion-resistant alloys combined with optimized welding techniques and surface treatments. This also eliminates stress concentration risks while maintaining consistent performance in chloride-rich environments.

How Wodon Leads the Wear-Resistance Industry
From material selection to structural design, Wodon customizes pipes for every dredging scenario. One operating condition, one engineered solution. With two decades of expertise, we’ve perfected an integrated process spanning: Site condition analysis → Advanced material R&D → Manufacturing innovation.

Wodon’s durable pipes also deliver sustainability benefits: reduced steel consumption through fewer replacements, compatibility with clean methanol fuels lowers carbon emissions.
As this Wodon-pipes-equipped mega-dredger operates in deep seas, it demonstrates China’s growing mastery in critical marine components. Beyond creating "dredger armor", Wodon empowers China’s technological independence in marine engineering wear resistance.
