Elbows and elbows are tubes that change the direction of flow of the pipe.
The elbow only has the curved part of the pipe; the elbow includes a straight pipe at both ends in addition to the curved portion, and also refers to a processing method.
The elbow is a kind of connecting pipe commonly used in pipeline installation. It connects two pipes with the same or different nominal diameters to make the pipe turn at a certain angle. Elbows can be classified according to production process, bending degree, material, connection method, etc. For example, the same elbow can be a cast steel elbow, a 90° elbow, a stainless steel elbow, a threaded elbow, and the like.
A curved pipe, in addition to a pipe fitting for connection, also refers to a processing method. The elbow is to bend the straight pipe through processing means to achieve the purpose of changing the flow direction of the pipe. The production process and the finished product are called elbows. Since the bent pipe is processed by a straight pipe, there is a problem of uneven thickness. However, the elbow can be made on site according to the needs and can be made into a special angle.
The bending radius of the elbow is usually larger than the elbow; the mechanical strength per unit area of the elbow is usually greater than that of the elbow. In use, you can choose according to your needs. For example, in order to deal with the flushing of the pipeline fluid to the turning, the thick-walled elbow can be selected to achieve the purpose of erosion resistance; the large-radius elbow can also be used to reduce (disperse) the flushing force.
