ASME B16.9 Long Radius Elbow Pipe Fitting Manufacturers, Stockist, Suppliers – Seamless Elbow, Welded Elbow, Large Diameter Fabricated Elbow Factory

• We are a specialist manufacturer of long radius elbows or pipe elbows in size range of 1/2″ to 48″ in accordance with ASME B16.9. We also produce custom size elbows as per design or drawing from our customers. Elbows can be manufactured in seamless, welded or fabricated form. While seamless elbows can be produced upto size of 24″, we can produce welded and fabricated reducers upto a size range of 48″ or even higher in some cases.
• A pipe elbow is a pipe fitting that helps an engineer to change the direction of the pipe in a piping system. According to the angle, there are three most commonly used elbows 45°, 90°, and 180° according to engineering needs. An elbow is one of the most commonly used type of buttweld pipe fittings, produce as per ASME B16.9 dimensional specifications.
• What is a Long Radius Elbow?
  • The center to face distance for a “long” radius elbow, the LR radius elbows have a center to end distance that is 1.5 times the NPS in inches (R = 1.5D), if it is more than 1.5 times, it is a bend. D is the diameter of the elbow. Long radius elbows are more commonly used compared to short radius elbows. Generally, the default is also a long radius. Where the pressure is high or the flow rate is high, a long radius is used. If the resistance of the solid conveying pipe is strict, a larger radius elbow is used.
  • L/R 45°Elbow – Long radius 45 degree elbow changes the direction by 45 degrees.
  • L/R 90°Elbow – Long radius 90 degree elbow changes the direction by 90 degrees.
  • L/R 180°Elbow – Long radius 180 degree elbow changes the direction by 180 degrees.
• What is a Short Radius Elbow?
  • Short radius elbow’s radius is equal to the NPS in inches (R = 1.0D). Short radii are generally used in low pressure fluids or where the elbows are limited during installation. Long-radius elbows are preferred if there are no conditions or are not specified in the contract.
  • S/R 45°Elbow – Short radius 45° elbow changes the direction by 45 degrees.
  • S/R 90°Elbow – Short Radius 90° elbow is same as LR90 except for the measurement between end of elbow to center line is 1 x NPS.
  • S/R 180°Elbow- Short Radius 180° return bend allows complete reversal of flow.
