Scope of use of elbow:
Because the elbow has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, freezing, health, water heating, fire, power, aerospace, shipbuilding and other basic engineering.
Technical requirements for elbow:
Bend requires control of radius of curvature. For example, if the radius length is 1.5D, then 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 quality of welding, the end of the car groove, leave a certain Angle, with a certain edge, this requirement is also more strict, the thickness of the edge, the Angle of the number and the deviation range are specified, geometric size than pipe fittings more than a lot of items. The surface quality and mechanical properties of the elbow are basically the same as those of the pipe. In order to facilitate welding, the steel material of the pipe to be connected should be the same.
he elbow is a pipe fitting that changes the direction of the pipe
In the piping system, the elbow is the pipe fitting that changes the direction of the pipeline. According to the Angle, there are 45° and 90°180° three most commonly used, in addition, according to the engineering needs also include 60° and other abnormal Angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The connection modes with the pipe are: direct welding (the most common way) flange connection, hot melt connection, electric melt connection, thread connection and socket connection, etc. According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow and so on. Other names: 90 degree bend, right Angle bend, love bend, etc
