Details of carbon steel Pipe Elbow , A234Wpb elbow :
LR 90 Elbow: Fittings that change direction in a piping system are called elbows. The directional change is given in degree such as 45 or 90. Long radius 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.
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.
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.
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.
Buttweld Pipe Fitting Specification & Standards
Welded Pipe fittings are made as per ASME spec B16.9. Asme B16.9 covers factory made wrought steel butwelding fittings in sizes 1/2" to 102". This standard however does not cover low pressure corrosion resistant buttwelding fittings. See MSS SP-43, Wrought Stainless Steel Butt-Welding Fittings.
Carbon Steel Welded Fitting:
A234 WPB is the most common material used for carbon steel butt welded fittings.
Astm A234 WPB is the Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service.
