Following shared by the Malleable Iron Pipe Fittings Supplier.

Elbow and elbow are pipe fittings that change the flow direction of pipes.

A bend is only the bend of a pipe. In addition to the curved part, the elbow also includes straight pipes at both ends, and also refers to a processing method.

Elbow is a kind of pipe fitting commonly used in pipe installation, connecting two pipes with the same or different nominal sizes to make the pipe turn at a certain Angle. Elbow can be classified according to production process, degree of bending, material, connection, etc. For example: the same bend can be cast steel elbow, the 90 ° elbow, stainless steel elbow, thread Angle, etc.

Elbow pipe, in addition to connecting pipe fittings, also refers to a processing method. Bending pipe is to bend straight pipe through processing means to change the flow direction of pipeline. Both the process and the finished product are called elbow tubes. Because the elbow is straight pipe processing, there is the problem of uneven thickness. But the elbow can be made on site according to the need, can be made into a special Angle.

The bending radius of the bend is usually greater than that of the bend; 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 erosion of pipe fluids on the bend, the thick-wall elbow can be selected to achieve the purpose of erosion resistance. Large radius elbow can also be used to reduce (disperse) scour force.
