Wear-resistant pipe type and technical knowledge


 

Wear-resistant pipe type and technical knowledge
    Introduction to ceramic lined composite pipe wear performance
    Application range: excellent wear resistance, thermal power plants, good corrosion resistance metal mines, excellent resistance to high temperature metallurgy reliable anti-fouling properties of coal washing plant, a high degree of impact resistance cement plant, the smaller the running resistance , wear-resistant ceramic lined composite pipe with the traditional steel pipe, wear-resistant alloy steel pipe, cast pipe and steel plastic, steel, rubber tube has the essential difference. Ceramic-lined composite steel outer pipe, the inner layer is corundum. The corundum layer Vickers hardness up to 1100-1500 (Rockwell hardness of 90-98), the equivalent of tungsten-cobalt hard gold. Wear resistance than carbon steel pipe more than 20 times higher than bonding usually made of corundum grinding wheel performance far superior, ceramic lined composite steel pipe high wear resistance, resistance to fluid erosion.

   High-temperature wear-resistant alloy pipe
    Closely related to the development of high-temperature wear-resistant alloy pipe with the rapid development of the power industry. Recalling the era of development of the steam turbine and boiler the low operating parameters, low-carbon steel has been able to basically meet the requirements. The beginning of this century, with the continuous improvement of the boiler and steam turbine operating parameters, the key developed into pearlite low-alloy steel, chrome key steel aluminum, chromium vanadium steel. Figure 1-2 lists the relationship has developed into a low-alloy pearlitic heat resistant steel lasting strength and temperature. The figure shows that the normal operating temperature of the carbon steel at 450-480 ° C. Developed steel containing 0.5% key success to improve the working temperature to about 500 ° C, containing key 0.5 W steel in the temperature range of 450-4801C lasting Child 1.5-2 times higher than carbon steel low-alloy chromium-phase steel and chromium aluminum vanadium steel rupture strength than carbon Na and tangent to the high operating temperature of .500-550 C. Now, the multiple composite alloying low alloy hot steel kettle when successfully developed, again Ke furnace and Yan turbine The working temperature was increased to 600-6201C.

   Alumina ceramic chip lined with wear-resistant pipe
   Alumina ceramic chip lined with wear-resistant pipes, alumina ceramic sheet lined with wear-resistant pipe, my company's ceramic chip main specifications are as follows: ceramic chip classification: each pressure, mosaic, trapezoidal plate armor installed, head size, 92,95,97,99 alumina purity, thickness 60 * 40, 50 * 40, 30 * 25. Mosaic: 10 * 10 * 10, 10 * 10 * 5,17.5 * 17.5 * 5,17.5 * 17.5 * 10.
Alumina ceramic piece of adhesive glue is divided into: organic and inorganic plastic glue, according to the different temperature glue to paste. The inorganic adhesive temperature between 30-40 ℃, can not take the water (liquid). Organic glue temperature below 90 ℃, the organic glue temperature contest care about a little bit higher.
   I produced the top ten characteristics of wear-resistant pipe
   I produced the wear-resistant pipe excellent wear resistance, the power plant fly ash, mine tailings, the dredged sediment transport in wear life is 4-7 times that of steel pipe, which is three times the ordinary PE pipe above. Wear-resistant pipe is the molecular weight of more than 3.5 million of the ultra-high molecular weight polyethylene resin extrusion molding, more suitable for the transmission of electric power, chemicals, mining, dredging and other special industrial and mining enterprises in the media, wear-resistant pipe characteristically:
1, the impact resistance. Resistance to environmental stress cracking resistance, scratch resistance capacity in the various types of plastic in the first
2, the wear resistance is 4 to 7 times of the steel
3, a structure of saturated molecules, chemical properties are very stable, the ability of a variety of corrosive media and organic solvents erosion
4, with the non-tackiness, its chemical and physical polarity lower than the ordinary plastic
