What does SDR 26 mean?

An SDR 26 means that the outside diameter (D) of the pipe is 26 times the wall thickness. Courtesy: Supply Hog. The higher the SDR number, the lower the level of pressure it can handle. This is because a high SDR number indicates a great internal surface area is subject to the internal pressure.

What is SDR 26 PVC pipe used for?

SDR-26 is commonly used in sewer applications. Specific applications include gravity and non-pressure drainage of sewer and surface water where extra heavy wall SDR-26 is specified. However, it is not to be used in wellfield protection areas and at depths greater than 13 feet.

What is stronger SDR 35 or SDR 26?

SDR 26 is rated at a minimum pipe stiffness of 115 psi (790 kPa) in accordance with the ASTM D2412 standard. SDR 35 is rated at 46 psi (320 kPa) in accordance with ASTM D3034 and D2412 standards.

Is SDR pipe the same as PVC?

The terms “dimension ratio” and “standard dimension ratio” are widely used in the PVC pipe industry. Both terms refer to the same ratio, which is a dimensionless term that is obtained by dividing the average outside diameter of the pipe by the minimum pipe wall thickness.

What is the difference between SDR 26 and SDR 35?
