Pipe Bend and Elbow difference | Longrun

 Pipe elbows and pipe bends are both very common pipe fittings products which are used to change the flowing direction in  a piping systems.
Some times they are interchangeable,but not the same one.
 
A pipe bend means a piece of pipe which are bent to some angle to join two pipings. They can be nearly any bending radius and angles.Pipe bends are commonly produced on site to meet a specific need by hot induction bending or cold bending. A elbow means a specific pipe bend as per the standard ANSI/ASME B16.9(or EN 10253.or other pipe fittings standards).Commonly the elbows have a bending radius of 1.5D or 1D(Here the D means norminal diameter of this bend),which are called “Long Radius elbow” or “Short Radius elbow”.and the angle of an elbow is 45degree or 90degree usually,some times there are also custom-designed elbows which are 30 degree,60degree,180degree or other angles.
Pipe Bend and Elbow difference
The pipe bends should be as per the standard of ANSI/ASME B16.49 which did not specific the bending radius and angle,the regular pipe bend radius are 2.5D,3D,5D,7D or 8D,but it can be any other bending radius according to the design need,and the bending angle can be in any degree,5,10,15,90 degree or any other degree.
 
People said “All bends are elbows but all elbows are not bend”,It is not ture.Actually “All elbows are pipe bends but not all bends are elbows” is more reasonable.
