Summary:cost performance of Yao Yu chromium carbide overlay plate is obvious with its good wear resistance and long long life.

The dredger cost is much higher than that of cruise and bulk carriers, and mud conveying pipe and mud pump liner cost is a very small fraction of the whole dredger cost.

When dredger digging coarse and fine sediment with high hardness, dredging pipeline and mud pump liner abrasive wear problems are very serious.


According to dredger field construction experiences of a project, mud discharging pipe has to suffer wear of 1 million m3 per 1mm during transportation, pipe wall has to worn out 12mm each year, maintenance and project delay loss is very large if we send dredger back to factory. We have to lose 1million per day, which does not include maintenance costs.

Especially to foreign operations, dredge maintenance costs is much more higher as we can image. We have to be involved into compensation for the contract fulfillment if there is some delay in project.  In this case, cost performance of Yao Yu chromium carbide overlay plate is obvious with its good wear resistance and long long life.
