What is the pipe bend?

The pipe bend 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 bending angle can be in any degree, 5, 10,15, 90 degree or any other.

Industrial processes:

Bending, squeezing, pressing, forging, machining and more

Industries served:

Our pipe bends are widely used in many industries, such as power generation, petroleum, natural gas, chemicals, shipbuilding, heating, papermaking, metallurgy and so on.

What is the pipe elbow?

30 degree, 60 degree, 180 degree Elbow

30 degree, 60 degree, 180 degree Elbow

Elbow means a specific pipe bend as per the standard ANSI/ASME B16.9 (or EN 10235 or other pipe fittings standards). Commonly the elbow have a bending radius of 1.5D or 1D (here the D means nominal diameter of this bend), which are called “Long radius elbow (LR elbow)” or “Short radius elbow (SR elbow)”. And the angle of an elbow is 45 degree or 90 degree usually, sometimes there are also custom-designed elbows which are 30 degree, 60 degree, 180 degree or other angles.

Long radius elbow are used when:

  • There is a need to keep the frictional fluid pressure loss down to a minimum.
  • There is ample space and volume to allow for a wider turn and generate less pressure drop
  • The fluid being transported is abrasive or has solids in it.

Short radius elbow are used when:

  • There is a need to reduce the cost of elbows
  • There is a scarcity of space and volume to allow a long radius type

APPLICATION OF PIPE ELBOWS:

Petroleum, chemical, power, gas, metallurgy, shipbuilding, construction, etc.
