2. Introduction
1)An elbow is a piece of pipe that changes the direction of a pipe. According to the Angle, there are 45°,90° and 180°common elbow, in addition, according to the needs of the project also includes 60° and other abnormal Angle elbow.
2)The connection modes with the pipe include: direct welding (the most common way) flange connection, hot melt connection, electric melt connection, thread connection and socket type connection, etc. 3)According to the production process can be divided into: welding elbow, punching elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree bend, right Angle bend, Love and bend, etc.
3. Application
1)Because elbow has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, freezing, sanitation, plumbing, fire fighting, electric power, aerospace, shipbuilding and other basic engineering.
2)Elbow is a kind of pipe fitting used for pipe turning. In all the pipe fittings used in the piping system, the proportion is the largest, about 80%. Usually, different forming processes are selected for elbows of different materials or wall thicknesses. The seamless elbow forming process commonly used in the factory is hot push, stamping, extrusion and so on.
