Bimetal wear resistant high chrome alloy tube

Steel – High-chromium-nickel alloy composite pipe complex by the outer wall and the inner liner is made of 5-12mm thick wall seamless steel pipe, lined 6-25mm thick high-chromium-nickel alloy, centrifugal composite made of straight pipe, pipe vacuum negative forged, the product takes full advantage of the large seamless steel pipe bearing capacity, high hardness and good welding performance of high chromium-nickel alloy (HRC55 – 60), is an ideal abrasion pipeline.
Wear-resistant pipes including wear elbow, straight pipe, structural tee, head size, radius sections, adjustable tube, mainly for pneumatic pumping slurry pipelines and other materials.
Because the transmission medium with high hardness, flow speed, flow rate, etc., can effectively reduce the transmission medium to produce long-lasting impact on the wall, wear, corrosion fatigue resulting in the duct velocity gradually being worn.
Delivery has been around electricity, metallurgy, coal, petroleum, chemicals, building materials, machinery and other industries, and high-speed developing. When transporting large grinding abrasion resistant material inside the pipe (such as ash, coal, mineral powder, tailings, cement, etc.), there is a wear-resistant pipe wear quickly, especially elbow wear faster . When the inner wear has strong corrosive piped gas, liquid or solid, the presence of corrosion and wear quickly damage the pipe is a problem. When the inner wear-piped with a high temperature material, there is a heat-resistant steel prices are very expensive problem. After the wear-resistant pipe market, these problems are solved. Wear-resistant pipes are widely used in severe wear mine backfill, ore powder and tailings transport, coal-fired power plant feed powder, slag, ash and other wear-resistant pipes are also very suitable. Wearable strong pipeline is to transport corrosive acids, bases, salts and abrasion both solid, liquid delivery pipeline ideal abrasion. Wear resistant pipe corrosion at high temperatures, high temperatures or high wear occasions ablation using very safe and reliable.
Superior characteristics of high wear-resistant chromium-nickel bimetallic tubes – Steel:
1, wear-resistant performance is good:
The composite pipe lined with high-chromium-nickel alloy, hardness HRC55 ~ 60, is a high abrasion resistance materials. Using special compound modifier grain refinement, greatly improving the toughness of the product, the tensile strength. Elbow eccentric production, wear much better than steel – ceramic composite pipe.
2, the pressure big:
The outer wall of seamless steel pipe products, is a big hub bearing technology, lined with high-chromium-nickel alloy to resist abrasive wear, not to withstand high pressure, the more rare wearable steel pipe, steel – ceramic composite tube to better ensure safe operation, so the product combination used for high pressure and high concentration of long-distance transport pipe.
3, high temperature:
Lined with high chromium-nickel alloy can be applied without modification at 600 Centigrade premise, no oxidation, and to maintain high wear resistance.
  4, good corrosion resistance:
High chromium-nickel alloy for 5% or less of sulfuric acid, hydrochloric acid, hydrofluoric acid, caustic corrosion performance reached more than 99%.
5, good appearance, anti-fouling:
The appearance of seamless steel pipe products, greatly improving the appearance of the product quality, the installation can improve engineering standards, lined with centrifugal and vacuum forging, smooth wall, greatly improving the ability of anti-fouling pipeline.
6. Installation facilitate:
The outer wall seamless steel pipe specifications, greatly facilitate the design and installation of the pipe, while the welding performance is good, can be welded, flanged connections.
The main application of high wear-resistant chromium-nickel bimetallic tubes – Steel:
Thermal power plant coal transportation system, wet dry ash conveying pipe, gravel coal system
Other power delivery system particles
All kinds of mining material handling
Hydraulic transmission systems and larger particle size slag slurry transportation
