Application of wear-resistant and corrosion-resistant alumina ceramic tube in pipeline transportation petrochemical
product introduction:
Product Features
1. Wear resistance: Under the same conditions, it is more than 10 times more wear-resistant than ordinary pipelines and has a long service life.
2. Corrosion resistance: The ceramic lining and inorganic adhesive have excellent corrosion resistance to different corrosive media, and can resist acid and alkali corrosion.
3. Moderate temperature resistance: It can operate at 350 ℃ for a long time and can meet general working conditions.
4. Smooth inner and outer walls, unobstructed airflow: The smooth surface allows materials to pass freely without hanging or blocking.
5.Easy to install: 1/3 lighter than ordinary pipelines, easy to transport, and saves manpower; Installation is easier and faster, making it easy to erect pipelines higher.
6.Reduce the load on support and hanger equipment and save material costs.
Product Application
Used for elbows and pipelines in pneumatic conveying systems in industries such as thermal power, metallurgy, steel, coal, cement, petroleum, and chemical engineering.
For example:
1. The pipeline of the power plant boiler pulverization system includes the powder conveying pipeline, coarse and fine powder separator pipeline, coal drop pipeline, primary air pipeline, secondary air pipeline, tertiary pipeline, and burner pipeline of the combustion system, as well as the slag discharge pipeline, return powder pipeline, and dry ash conveying pipeline of the ash removal and slag discharge system;
2. Wear and tear bends such as raw material transportation pipelines, material collection pipelines, dust removal pipelines, ash discharge pipelines, ash drop pipelines, batching and mixing pipelines, mill outlet pipelines, coal burning pipelines, coal powder pipelines, separator pipelines, burner square and circular pipes in steel plants;
3. Wear bends such as the outlet pipeline of the cement plant's selection machine, the inlet pipeline of the selection machine, the dust collection pipeline, the vertical mill outlet pipeline, the circulating air pipeline, the high-temperature fan air pipeline of the coal mill, and the feeding pipeline;
4. Various pipe fittings for processing and conveying materials in petroleum, chemical, mining, coal, coal washing plants, smelting, papermaking, aluminum industry, building materials, powder engineering, grain machinery, etc.
