Elbow to production methods can be divided into pushing, pressing, forging, casting and so on. To manufacturing standards can be divided into GB, electricity standard, standard ship, chemical, water standard, American standard, German standard, Japanese standard, Russia and other standard. By its radius of curvature of points: can be divided into long radius elbows and short radius elbows. It refers to a long radius elbow radius of curvature equal to 1.5 times the outer diameter of the pipe bend 90 degrees hot, i.e., R = 1.5D; refers to its short radius elbow radius of curvature equal to the pipe diameter, i.e. R = 1.0D. (D is the diameter of 90-degree elbow elbow pressing manufacturers, R is the radius of curvature). In terms of pressure levels to points: about seventeen species, and the American standard pipe is the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; most commonly used two kinds of STD and XS. Purposes in accordance with different shapes can be divided into: grooved elbow, elbow card sets, double socket elbow, flange elbow, reducing elbow, elbow seat stay, and external teeth elbow, elbow punching, pushing system elbow, socket elbow, butt welding elbow, elbow, etc. within the wire. The material commonly used high-pressure elbow quality steel, stainless steel or alloy steel Cangzhou supply elbow 90 degrees hot, high-pressure elbow can withstand high pressure in a variety of high-pressure pipeline and the pipeline can withstand the corrosive fluid. Installation of high-voltage high-pressure pipe elbow pipe installation with medium and low pressure piping installation requirements similar, but more demanding elbow 90 degrees hot sell low-priced, more stringent regulations, therefore, in addition to the requirements, the low-pressure pipe installation requirements, The following requirements shall be executed yet. Used to install the high-pressure pipe, fittings, fasteners and valves must have passed the test, along with the corresponding technical documentation, should keep transported to the scene, clearly marked, placed neatly. Before installation, it should be the inner and outer surfaces wipe clean, and check whether the channel foreign body is smooth. Check the nozzle and gasket sealing surface roughness meets requirements, may not affect the sealing performance of the sealing surface scratches (scratches, especially radial), spots and other defects.
