Works with the elbow, 3D 2D 1D 316 stainless steel elbow the Hongyuan pipe industry production: a multiple of elbows, high pressure elbows, IF Big Bend. (Contact: Ma Yuanyuan phone: 18,732,703,585 QQ: 619 688 609) company mainly engaged in a variety of materials pipe: 304,304 L, 316,316 L, 321,310 S ,18-8, 16Mn, 20 #, 20G, 12Cr1MoVG, P91, 10CrMo910, 15CrMo F51 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.
