Rare earth metal wear resistant pipe

Rare earth alloy wear-resistant tube

The rare earth alloy wear- esistant pipe is used for pneumatic, pump slurry, etc. Rare earth alloy wear resistant pipe has the characteristics of fast velocity and high flow rate. The conveying medium temporarily continues to produce impact on the pipe wall, wear, corrosion and so on, which causes the pipe to become tired and gradually wear out.

Rare earth alloy wear-resistant tube是在磨损严重的部位,如管道、弯头、异径管、吸水口等处采用模型整体铸造,然后再进行机械加工的 方法,特别是在弯头外侧磨损尤为显著的部位,对外径采用变更圆心的方法进行设计,使磨损严重的部位局部加厚,而且还能根据各种要求,制作出各种不规则开关的管件来满足设计要求,直管是采用离心铸造。稀土耐磨合金中含有Cr、Ni、V、Mo、W、Cu等多种合金元素,它不但具有较高的硬度,还具有一定的机械性能,在常温下具有良好焊接性能,并具有可切割性和现场开孔的可能性,同时还具有一定的抗腐蚀性能。

Because the outer surface behaves like mild steel, the product can be cut and welded with proper procedure in the field, configured into a variety of fittings, and can accept the standard end options of flanges, weld rings and couplings.

Abrasive Applications

One-hundred-twenty-nine-million tons of coal ash—a byproduct of the coal burning process—is produced every year. Most power plants transport the coal ash in liquid form to large surface impoundments or in solid form at landfills near the facility through long lengths of steel piping, which can range in length from several thousand feet to miles.
