The Hongyuan professional production: cold bending bends and hot simmer elbow. Manufacturers supply: 3D 2D 1.5D elbow WPL6 Chilling simmer Big Bend (Contact: Feng Hongmei Contact: 15932713817, E-mail: 1763757819@qq.com Company Website: http://www.czhypipe.com/) Cangzhou macro source Pipe Co., Ltd. is a steel sales and pipe fittings, as one large comprehensive enterprise. The company is located in the pipeline equipment industry in China to create a base - Hebei Yanshan. The east Bohai Huanghua Port, north of Beijing and Tianjin, the environment and convenient transportation. The company mainly engaged in the pipes of various materials: 304,304 L, 316,316 L, 321,310 S ,18-8, 16Mn, 20 #, 20G, 12Cr1MoVG, P91, 10CrMo910, 15CrMo 1 Quality: has passed ISO9001 international certification pressure vessel manufacturing license. 2 Finish: rust-proof black paint, anti-rust varnish, transparent anti-rust oil, hot-dip galvanizing, cold galvanizing, 3PE coating, epoxy coating. In the pipeline project, according to the different production methods should be divided into: Big Bend simmer Big Bend, stamping bending and welding. The elbow is expressed as the thickness of the outer diameter X. 108X6. Bending radius from 1.5D up. 1.5D elbow, upward bend the. The simmering Big Bend is divided into cold simmer and heat simmer two with telescopic good elasticity, resistance to high voltage, resistance, and the advantages of small, they have been widely used. 2. Production methods can be divided into a push system, pressing, forging, casting, and so on. 3 manufacturing standards division can be divided into the GB electricity standard, the ship standard of standard water standard, American standard, German standard, Japanese standard, the Russian standard, such as. 4: its radius of curvature can be divided into long-radius elbows and short radius elbows. Elbow It has a radius of curvature equal to 1.5 times the outer diameter of the tube, i.e. R = 1.5D; short radius elbow which is the radius of curvature is equal to the pipe diameter, i.e. R = 1.0D. (D is the elbow diameter, R is the radius of curvature). 5. Pressure levels: about seventeen, and tube standards in the United States is the same,: Sch5s, Sch10s Sch10, Sch20, Sch30, Sch40s, STD, Sch 40 has an Sch60 Sch80s, XS; Sch80 SCH100, Sch120, Sch140, Sch160, XXS; One of the most commonly used in both the STD and XS.
