wear resistant chromium carbide plate for dredge pipes

The dredge pipes are made of common low carbon steel plate Q235 or 16Mn steel plate that has good strength before we introduced chromium carbide composite wear-resistant plate to the dredging industry. The service lifetime of low carbon steel plate Q235 is different according to wear degree and applications, but basically approx one and a half years, or even shorter when the wear materials are quartz sand and clay.

Hardfacing repair was widely used when common steel pipe was penetrated and damaged, it requires heave welding workload, the construction quality is not ideal as well, repeated repair is also necessary for some heavy wear abrasive areas. Moreover, we also requires a certain period to make new dredge pipes and need to stop construction if we have to replace steel pipes, which could affect the dredger construction state directly.

With the development of wear resistant materials, various wear resistant materials were applied to dredging industry and greatly improve the construction efficiency of dredgers. Since YaoYu chrome carbide overlay plate and overlay pipes were applied to dredging pipeline, no matter in ASTM G65 abrasion test or the actual applications, YaoYu chromium carbide plate has been approved to be the best of wear resistant performance and was superior to ordinary carbon steel plate.
