Shanxi steel factory direct hot elbow, elbow Shanxi steel, carbon steel elbow hot. Over the years manufacturers have faith pursuit of excellence, honesty, cooperation and win-win concept, according to the enterprise standardization needs to adapt to market-oriented production, the full introduction of modern enterprise management mechanisms, carefully regulate the internal management, and people-oriented, harmonious development, bold innovation, with the improvement of technology, strong market development, I plant products have been widely used in petroleum, chemical, metallurgy, machinery and other engineering fields, are exported abroad and medium-sized enterprises, by all users, welcome your inquire! skills for the manufacture of carbon steel elbow working pressure is less than 10MPa, the inside diameter carbon steel elbow d125mm, diameter D and inner diameter d ratio of carbon steel elbow bend in the D / d? 1.5 Any carbon steel elbow, while the diameter carbon steel elbow unlimited size. For example, can be processed carbon steel elbow inner diameter of 12m, 60m diameter carbon steel elbow in more large steel raw GB elbow. Carbon GB elbow oil, gas, chemicals, utilities, construction and boiler piping system other professional. Carbon steel elbow link interface for tongue and groove sealing surface, for flammable, explosive, toxic medium and high pressure applications. A gasket is capable of plastic deformation, and the strength of the material must have a ring made. Carbon steel elbow (HG20600, GB / T9121, JB / T83) manufactured relatively simple, mainly used in corrosive media with a pipeline system; elbow calm solder ring is not the same information can be used to reduce elbow costs, improve performance. Elbow have raised face sealing surface, convex surface, Mortise face material for stamping elbow requirements are:. ① thickness cut indeed, on average. Stamping mold careful, small gap, sheet thickness spend large deformation force will increase and cause the material, and even die bursting; sheet too thin may affect product quality, even when deep crack in the pull. ② profile clean, no spots, no scars, no bruises, no overview of crack. Chronological overview defective products will remain in the workpiece profile, crack defects in bending, deep drawing, forming and other course outline to the breadth and depth extensions, resulting in waste. ③ plastic deformation of the sheet in the drawing, bulging, etc., different plastic deformation, etc., will not mean deformation, so forming inaccuracies caused by defective products or waste. Pressing the pipe elbow is heated using professional equipment molding, and then heated to above the critical temperature cutting, holding time soon after into the quenchant, its temperature suddenly decreased, greater than the critical cooling rate of the rapid cooling method made of elbow. Carbon steel pipe elbow is to change the direction of the metal pipe fittings. Connections are threaded and welded. 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.
