Standard and use range of wear resistant fittings
Wear resistant pipe mainly includes wear-resisting bend, straight, tee, reducer, Fangyuan Festival, reducer structure, mainly used for pneumatic pump, slurry feeding and conveying pipeline. Because of the high hardness, high flow rate and flow characteristics of the transport medium, the medium has long lasting impact on the pipe wall, wear, corrosion, etc.. According to the different wear conditions, the wear resistant line is also different. Wear-resisting ceramic liner pipe (lining of aluminum oxide, silicon carbide, zirconia, silicon nitride, Theron, aluminum nitride, boron nitride and other); wear-resisting alloy pipe; tortoiseshell net wear-resistant pipe fittings; steel and rubber wear resistant pipe; wear resistant steel plastic tube; wear-resistant cast stone pipe; wear self propagating composite pipe; dilute soil wear-resistant alloy tube.
Wear resistant pipeline
Wear-resisting bend except for coal-fired power plants in addition to ash, slag discharge pipe, powder, powder return pipe, desulphurization pipe, also widely used in the following industries:
Mine coal industry: coal water slurry, coal sludge, coal mine, mine filling;
Metal mines: the transfer of the concentrate and tailings;
Metallurgy: Iron and steel plant iron blast furnace slag conveying pipeline, etc.;
CAO, zinc Bei sand conveying pipe, conveying wear-resisting bend iron alloy, refining and other preferred steelmaking;
Cement factory: wet process rotary kiln production line of raw slurry conveying, pulverized coal conveying, lifting machine material, finished cement pneumatic conveyor loading and unloading, concrete conveying wear-resisting bend.
Chemical plant: the coal conveying pipe, powder material conveying wear-resisting bend
Advantages of wear resistant pipeline
Steel, wear-resistant pipe and traditional wear-resistant alloy cast steel, steel, steel tubes and rubber tube has essential difference. Wear resistant pipe outer layer is seamless steel pipe, the inner layer is corundum. The hardness of corundum layer is HV1100-1400, which is equivalent to 20 times higher than that of carbon steel. Wear-resistant pipes and wear resistance is mainly rely on the inner layer several millimeters thick alumina layer, this than alloy wear-resistant cast steel pipe, cast stone pipes on both composition and microstructure, also depends on the thickness of wear has been a qualitative leap.
Wear resistant pipeline quickly occupied the market, in addition to high quality, good performance, but also in its performance price ratio is higher than other wear-resistant corrosion-resistant heat pipe. In the same specification of unit length and wear-resisting pipe, wear-resisting pipe weight only the wear-resistant alloy cast steel pipe of about, the per meter project cost decrease by 20% - 30%; cast stone only a third of the weight of the tube, per meter reduce engineering cost 5% - 10%; wear resistant pipeline used in high-temperature and corrosive occasions, only the price of stainless steel tube, nickel titanium tube of a fraction of
