standard pipe bend radius chart shows the bending radiuses available in pipe bending products. Pipe bends are pipe fittings whose bending radius can range from 1D to 10D generally. There are different dimensions and categories in the standard bend radius for pipe fittings. The bending radius is expressed in relation to the pipe’s outer diameter. If the radius is equal to the pipe diameter then the radius is 1D. The radius is 2 times greater than the outer diameter then the pipe bend is 2D. There are also different standard pipe bend angles ranging from 15% degrees to 180 degrees.

Pipe Bend Radius Chart
The angle defines how quickly or slowly the direction of flow is changed and what kind of pressure is excerpted onto the pipe bend wall as a result of the change in direction. To know that different bending radiuses and sizes of the pipe bends, please contact us to receive a pipe bending radius chart. This chart provides the available pipe bend radiuses with wall thickness and the size of the bending. There are different specifications to cover different application requirements and the pipe bending can be made from any different material grade.
The most used materials are austenitic stainless steels and carbon steels. You can contact us to know more about the standard pipe bend size, pricing, dimensions and material grades. The application of the pipe bends can be seen in many piping applications such as general corrosive services, water lines, oil and gas, petroleum and other industrial piping applications.
