Elbow
Steel pipe elbow is a key parts in a piping system for to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe turn to a certain direction.
According to fluid direction of the pipelines, elbow can be divided into different degrees, such as 45 degree, 90 degree,180 degree, which are most common degrees. Also there has 60 degree and 120 degree, for some special pipelines.
Elbows are split into two groups, if the radius is the same as pipe diameter (Center-to-Face dimension of 1.0 X diameter ), it called Short Radius Elbow (SR elbow) used normally for low pressure and low speed pipelines or in tight areas where clearance is the main issue. If the radius is larger than pipe diameter (Center-to-Face dimension of 1.5 X diameter) then we call it a Long Radius Elbow (LR Elbow) used for high pressure and high flow rate pipelines.
As per the connection with pipe, elbows could be classified as Butt Welded Elbow, Socket Welded Elbow and Threaded Elbow. According to the valve body material, it has stainless steel, carbon steel and alloy steel elbow.
