What is Elbow and Bend
Fittings that change direction in a piping system are called elbows. Pipe elbows are used to be installed between two lengths of pipe or tube allowing a change of direction,usually these elbows distinguished by connection ends.
The pipe bending is used to change the direction of run of pipe.It advantage is can matach long distance transition requirements,so it is commonly that bends dimension according to customer design
Elbows bends 45° – 90° – 180° LR/SR
The function of a Pipe Elbow is to change direction or flow in a piping system. By default, there are 5 opportunities Radius Elbow Bend, the 45°, 90° and 180° elbows, all three in the “long radius” version, and in addition the 90° and 180° elbows both in the “short radius” version.
LR 90 Elbow: LR Elbow 90 degree elbow has the center line of elbow at 1.5 x NPS from eblow end. 3R elbow has center line at 3 x NPS from elbow end.
LR 45 Elbow: Long radius 45 degree elbow changes the direction by 45 degrees.
LR 180 degree Bend: Long Radius 180 degree return bend allows complete reversal of flow. The distance between end of elbow and center line is 3 x NPS.
SR90 Elbow: Short Radius 90 degree elbow is same as LR90 except for the measurement between end of elbow to center line is 1 x NPS.
SR 180 degree Bend: Short Radius 180 degree return bend allows complete reversal of flow but in a much tighter turn. The distance between end of elbow and center line is 1 x NPS.
