Aluminum elbow, making aluminum elbow, Waldorf fittings

Aluminum elbow, making aluminum elbow, Waldorf pipe fittings are supplied by China. Waldo Yanshan Pipe Fittings (www.yshuadu.com) is ShangMeng Hebei Cangzhou quality certified company, with brands such as Waldorf, has a good reputation, honesty, service-oriented "business alliance Service" icon on the page We will be happy to serve you! Waldo Yanshan Pipe Fittings located in the Bohai Sea a Yanshan Industrial Zone, covers an area of ??3600 square meters production of aluminum elbow, the registered capital of 5 million yuan, the company specializes in producing high, medium and low pressure pipe fittings, flanges and aluminum system pipe fittings products, since its inception, put manufacture high-quality products as the development of the company, from raw materials to the manufacturing process of re-examination of control, and the detection of the product after molding, all in strict accordance with the process technology requirements and quality assurance manual carefully executed to ensure that customers with quality products. Carbon steel pipe elbow is to change the direction of the metal pipe fittings. There are threaded and welded connections. By angle, there are 45 ° and 90 ° 180 ° three most commonly used, according to project needs another 60 ° also includes other non-normal angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics. Way connected with the pipe are: soldered directly (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, punching elbow, elbow push system, casting elbow. Other names: 90 degree elbow, right-angle bend, bend, etc. love. Carbon steel elbow requires normalizing heat treatment, machining port, wall thickness required to leave burning, machining allowances. Usually the balance of the theoretical thickness of the elbow 10% to 20%. Elbow wall thickness δ and the smaller cross-sectional diameter D ratio, the better the performance and fit the mold, but the elbow arc more likely to wrinkle. According to the plastic deformation of the metal in the constant volume, when pushed into shape constant wall thickness (actually slightly thinner), equal to the length of the outer arc tube elbow-length features, the outer diameter of the tube to push the system to derive the formula: If the actual choice of tube diameter ratio calculated according to the formula Dp value is less quality aluminum elbow, and fit the mold of good performance, but the elbow arc easy wrinkling. If the actual choice of tube diameter ratio calculated according to the formula Dp value large flat flange aluminum elbow, the result is just the opposite. Carbon steel elbow to determine the principles of the heating temperature is less than the elbow inner wall of the main material yield stress limit of the material at this temperature austenitizing temperature or more, and push the system time. Material austenitizing temperature, the higher the heating temperature; high temperature material yield limit, the higher the heating temperature.
