What does SDR pipe stand for?
standard dimension ratio
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 does SDR 26 pipe mean?
SDR 26 Pipe It is a standard that gives specific details regarding wall thicknesses and outer diameter across different PVC materials expected to achieve required pressure ratings. An SDR 26 means that the outside diameter (D) of the pipe is 26 times the wall thickness. Courtesy: Supply Hog.
Is SDR pipe PVC?
Scope: This specification covers (PVC) pipe made in standard thermoplastic pipe dimension ratios (SDR Series) and pressure rated for water. PVC PR-160, PR-200 and PR-315 are for pressure systems where temperatures will not exceed 140° F. They are highly resilient, with high-tensile and high-impact strength.
What is SDR-21 PVC pipe used for?
potable water supply lines
SDR-21 PVC solvent weld pressure pipes are suitable for potable water supply lines, transmission mains, sewage force mains, golf course, and other irrigation systems, oilfield saltwater disposal, stormwater disposal, well casings, industrial process piping, and other pressure applications.
What does SDR-21 stand for?
SDR-21 Pipe The SDR (standard dimension ratio) is a rating system for pressure pipework. The lower the pressure rating, the greater the SDR. An HDPE (High-Density Poly Ethylene) pipe’s SDR specifies how much pressure in pounds per square inch (PSI) it can withstand.
What type of pipe is SDR?
The SDR pipe is the “Standard Dimensional Ratio” and refers to the geometry of the pipe. SDR is defined as the ratio of the nominal outside diameter to the nominal wall thickness. Where dn is the nominal outside diameter of the pipe and en is the nominal (minimum) wall thickness of the pipe.
What is the wall thickness of SDR 26 pipe?
| Nominal Pipe Size | Average Outside Diameter | Minimum Wall Thickness (in) And Calculated ID (in) |
|---|---|---|
| (in) | (in) | SDR 26 |
| Wall | ||
| 1/8 | 0.405 | |
| 1/4 | 0.54 |
