Standard pipe bend radius chart showsthe bending radiuses available in pipes bending products. Piping bends are pipefittings whose bending radius can range from 1D to 10D generally. There aredifferent dimensions and categories in the standardbend radius for pipe fittings. Thebending radius is expressed in relation to the pipe’s outer diameter. If theradius is equal to the pipes diameter then the radius is 1D. The radius is 2times greater than the outer diameter then the pipes bends is 2D. There are alsodifferent standard pipe bend angles ranging from 15% degrees to 180 degrees.

Carbon Steel Pipe Bend

Long Radius Bend

The angle defines how quickly or slowly the direction of flow is changed and what kind of pressure is excerpted onto the piping bend wall as a resultof the change in direction. To know that different bending radiuses and sizesof the piping bends, please contact us to receive a pipe bending radius chart.This chart provides the available piping bend radiuses with wall thickness andthe size of the bending. There are different specifications to cover differentapplication requirements and the piping bending can be made from any differentmaterial grade.

The most used materials are austenitic stainless steels andcarbon steels. You can contact us to know more about the standard pipe bend size, pricing, dimensions and material grades.The application of the piping bends can be seen in many piping applications suchas general corrosive services, water lines, oil and gas, petroleum and otherindustrial piping applications.

Weight Formula for Cold and Hot piping bend

❖ Weight / kg = 0.0433 ( D – T ) TRθ / 100000 + L

 ➔ θ = Bend angle

 ➔ D = Outside diameter

 ➔ L = Weight of double sides straight length

 ➔ T = Thickness in mm

 ➔ R = Bend radius

✠ Calculating Wall Thickness

ISO 161-1 uses the following formula to calculate the wall thickness of pipes:

σs=PN.(da-s/20.s)=PN.S

σs = hoop stress (N/mm2)
