Featuring superior anti-scour and wear-resistant properties, Rare Earth Alloy Elbows are widely mounted at bent sections of pipelines used for solid powder and solid-liquid slurry transportation across various industries. Each industry has generated stable purchasing demand according to its unique characteristics of conveyed raw materials.
The thermal power industry is one of the largest application markets for Rare Earth Alloy Elbows. Within coal-fired power plants, such fittings are equipped on pneumatic conveying pipelines that deliver crushed raw coal to boilers, drain fly ash and bottom slag produced during unit operation, and circulate slurry for auxiliary environmental desulfurization systems. Pipe bends undergo the most concentrated abrasion along the whole pipeline, which results in frequent damage and replacement of conventional elbows. Able to adapt to the year-round nonstop production rhythm of power plants, Rare Earth Alloy Elbows resist continuous scouring from high-speed solid particles and help factories reduce production halts triggered by frequent pipeline maintenance. These pipe fittings can be commonly spotted in pipeline networks of large and medium-sized captive power plants and cogeneration stations.
Mining and coal preparation industries boast diversified application scenarios. After ores are mined from open-pit and underground mines, crushed ore is made into slurry and transported over long distances through pipelines to mineral processing workshops, while waste tailings are delivered via pipelines for centralized stacking. Hard mineral particles suspended in slurry create strong impact abrasion on pipe elbows. Meanwhile, coal washing facilities generate coal slurry and dense medium suspension in raw coal separation, which constantly abrade pipeline bends. Adapted to the harsh underground environment with high humidity and abundant impurities, Rare Earth Alloy Elbows perform well in both solid pulverized coal conveying pipelines and solid-liquid mixed medium delivery pipelines, covering the full process from raw coal washing to outbound tailings transportation.
Cement and building material production requires these elbows for full-range material conveyance. From transporting ground limestone and clay raw materials after raw material entry to conveying high-temperature calcined clinker and feeding pulverized coal into kilns, elbow fittings spread all over production lines. The kiln tail dust collection system gathers massive cement dust flowing at high speed to rub against pipe bends; together with rising ambient temperature, ordinary pipe fittings are prone to wall thinning and perforation. Rare Earth Alloy Elbows fit round-the-clock uninterrupted production, enjoying extensive application on clinker silo discharge pipelines and closed powder conveying piping. Their popularity is also growing among small and medium-sized building material manufacturers and new construction material powder processing plants.
The iron and steel metallurgy industry consists of multiple segmented production scenarios. Blast furnaces need continuous pulverized coal injection for combustion support, causing severe abrasion on elbows of high-pressure coal conveying pipelines. Steelmaking produces steel slag and dedusting ash that wear out waste collection pipelines badly, and mixed raw mineral powder in sintering workshops generates dense dust that abrades all bent pipe sections. Rare Earth Alloy Elbows stand as the preferred choice for bend positions across the complete conveying network of ironmaking, steelmaking and matched sintering processes, coping with complex on-site conditions filled with high-temperature dust and hard waste slag inside metallurgical plants.
Apart from the four core industries mentioned above, coal chemical engineering, fine chemical industry and aggregate processing enterprises keep expanding their adoption of Rare Earth Alloy Elbows. Chemical factories install them on sealed pipelines for granular catalyst and crystalline material transportation, while stone crushing plants fit finished aggregate air conveying pipelines with such elbows. Any working condition with abrasive hard particles tends to choose Rare Earth Alloy Elbows to cut daily pipeline maintenance costs. As domestic industrial automation and continuous production develop, the applicable scope of Rare Earth Alloy Elbows keeps expanding steadily.
