Pipe Co., Ltd. Hebei Chiho steel stamping elbow 90 degrees to production methods can be divided into push the system, pressing, forging, casting and so on. To manufacturing standards can be divided into GB, electricity standard, ship standard, technology standard, water standard, American standard, German standard, Japanese standard, the Russian standard and so on. According to its radius of curvature to the point: can be divided into long radius elbows and short radius elbows. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outer diameter of the tube, i.e., R = 1.5D; short radius elbow refers to its radius of curvature is equal to the pipe diameter, i.e. R = 1.0D. (D is the diameter of the butt welding thick-walled stamping elbow bend, R is the radius of curvature). In terms of pressure levels to points: Approximately seventeen species, and the US standard pipe is the same, there are: Sch5s, Sch10s, Sch10, Sch20 thick stamping elbow, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS ; Sch80, SCH100 large thick stamping elbow, Sch120, Sch140, Sch160, XXS; one of the most commonly used two kinds of STD and XS. According to the use of different shapes can be divided into: Reducing thick grooved stamping elbow elbow, elbow card sets, double bearing elbows, flanges elbow, reducing elbow, elbow seat stay, both inside and outside curved teeth head, steel stamping elbow, elbow to push the system, socket elbow, butt elbow, elbows, etc. inside. Japanese standard JIS B2311 Standard describes common steel pipe fittings JIS B2312 JIS B2313 steel pipe fittings steel pipe fittings made of steel socket welding pipe fittings JIS B2316 Chiho Pipe Co., Ltd. Hebei professional production of stamping and welding elbow, buy stamping elbow went to Hebei Chiho pipe industry. Stamping elbow. It is made of the same material of the plate and pipe stamping die stamping elbow into the ring halves, then two half-rings were set right elbow weld forming. Because different types of pipeline welding standards, usually in groups of semi-finished factory fixed spot, spot welded to the pipe seam construction grade, therefore, also known as the two halves welded elbow. Stamping elbow has a good overall performance, so it is widely used in chemical, construction, water supply, drainage, oil, light and heavy industrial, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding and other infrastructure projects. 90 degree elbow thick stamping, punching Hanzhong thick elbow, Hebei Chiho Chiho by Hebei Industry Co., Ltd.
