Pipe Elbow Fittings 3" A234 WPB
Seamless elbow: Different forming processes are selected for bends according to different materials or wall thickness. The seamless elbow forming process used by the manufacturer is hot push, stamping, extrusion and so on.
Technical requirements
required to control the radius of curvature. For example, if the radius length is 1.5 D, the radius of curvature must be within the required tolerance. Because most of these pipe fittings are used for welding, in order to improve the welding quality, the end part is groove, leaving a certain angle, with a certain edge, this requirement is also more strict, how thick the edge, how much angle and deviation range are stipulated. There are many more geometric dimensions than pipe fittings. The surface quality and mechanical properties of the elbow are basically the same as those of the pipe. For welding convenience, the material of the steel connected to the pipe is the same
Scope of use
Because the elbow has good comprehensive performance, it is widely used in chemical industry, construction, water supply, drainage, oil, light and heavy industry, freezing, sanitation, plumbing, fire fighting, electric power, aerospace, shipbuilding and other basic projects.
