The high chromium surfacing and wear resistant pipe produced by Shandong Qishuai is based on steel tube. The wear-resistant alloy is combined with the substrate metallurgy by surface welding technology. Its wear-resistant alloy layer is welded on the tube surface for 3 ~ 15mm, have the hardness 58 ~ 63HRC.
The composite wear resistant pipe has excellent abrasion resistance, high temperature resistance and impact resistance, and also has great toughness. It has excellent mechanical and thermal shock resistance and is easy to install. Mainly used for large cutter suction dredger, suction dredger, especially suitable for wear large granular materials, such as gold smelting slag system, an abandoned mine filling, dry material handling etc.. Compared with other wear resistant pipes, the product has long service life and economic benefits.
