Products are exported to overseas markets truly numerous. Should: widely used in industry, construction and maintenance needs power plants, petroleum, mining, chemical, metallurgy, shipbuilding, oil and gas, construction, machinery, etc., and has long exported to Italy, Iran, Egypt, South America and the Middle East, domestic outside of praise. Carbon steel pipe elbow is to change the direction of the metal pipe fittings. Connections are threaded and welded. By angle points, 45 ° and 90 ° 180 ° three most commonly used, according to project needs in addition also includes other non-normal 60 ° angle bend. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, steel, nonferrous metals and plastics. Way connected with the pipe are: direct welding (the most common way) flange connection, hot melt connection, fused connection, threaded connections and socket type connections. According to the production process can be divided into: welding elbow, pressing elbow, push the system elbow, casting elbow. Other names: 90 degree elbow, right angle bend, bend, etc. love. Welded steel elbow production process: carbon steel elbow is the use of self-propagating high temperature synthesis - centrifugation manufacture. The elbow is placed within the centrifuge tube mold, red iron added in the elbow and aluminum powder mixture, this mixture is called thermite in chemistry, when the centrifuge tube mold rotation reaches a certain speed, through a Mars ignite thermite, thermite burn themselves immediately, combustion wave spread rapidly, violent chemical reaction that occurs when spread. High temperature resistant ceramic SMD mount an inorganic binder in carbon steel elbow wall, it is AL2O3 as raw materials and rare metal oxides as solvent, 1730 ℃ high temperature sintering of special corundum ceramics, and then using wear-resistant adhesive junction combined into wearable ceramic chip, wear-resistant ceramic chip can choose according to different needs, to meet the technical conditions for users with special needs. Wear resistant ceramic patch is 280 times more manganese steel, high chromium cast iron is 180.5 times. Cangzhou LUCKY Pipeline Equipment Manufacturing Co., Ltd. is a production, processing and technology independent research in one entity class factory production and management, our company main products are elbow, flange, three crosses, reducers, elbows, caps waterproof casing, manholes, metal hose, carbon steel, alloy steel, stainless steel and other materials factory pipe, production execution ASTM, DIN, DLT, HG, JB, JIS, MSS, SH, SY, ROCT etc. production standard, non-standard products can be customized production. Company's main products: steel pipe fittings, pipe fittings Mo-resistant, anti-corrosion pipe fittings. Which steel pipe fittings include: elbows, bends, tees, reducers, flanges, head, pipe caps, high, medium and low voltage three series, the product material were carbon steel, stainless steel, alloy steel and users Other special requirements of metal materials, pipe fittings products Altogether thousands of specifications, models.
