What is SDR 11 HDPE pipe?
What is SDR 11 HDPE pipe?
A SDR 11 means that the outside diameter – D – of the pipe is eleven times the thickness – s – of the wall.
What does SDR 11 stand for?
Standard Dimension Ratio
SDR stands for Standard Dimension Ratio. The ratio referred to is the ratio between the Outside Diameter (OD) and the wall thickness. The resulting number is often used to determine the pressure capacity of the pipe. 409 the resulting number is 11.002. Therefore this pipe may be referred to as SDR 11.
What is the thickness of SDR 11 HDPE pipe?
SDR 11 Dimensions
| NOMINAL SIZE IN (MM) | OUTSIDE DIAMETER (O.D.) IN (MM) | WALL THICKNESS IN. (MM) |
|---|---|---|
| 2 (53) | 2.369 – 2.381 (60.15 – 60.45) | 0.153 – 0.173 (3.89 – 4.40) |
| 3 (78) | 3.492 – 3.508 (88.70 – 89.10) | 0.226 – 0.253 (5.74 – 6.43) |
| 4 (103) | 4.491 – 4.509 (114.07 – 114.53) | 0.290 – 0.325 (7.37 – 9.48) |
What is SDR 11 CPVC pipe?
SDR is Standard Dimension Ratio. SDR is a method for rating pressure piping. SDR= D/ S where ‘D’ is the outer diameter and ‘S’ is pipe wall thickness (mm). An SDR 11 pipe is outer diameter ‘D’ of the pipe is eleven times the thickness ‘S’ of the wall diameter.
What SDR means in pipes?
standard dimension ratio
July 6, 2021. The standard dimension ratio (SDR)—also referred to as the standard dimensional ratio—is a measurement and method often used by pipe manufacturers to rate the working pressure capacity of a pipe. It is calculated by determining the relationship of the pipe’s outside diameter to its minimum wall thickness.
Which is thicker SDR 11 or SDR 17?
is the standard diameter ratio (SDR). SDR 11 stronger than SDR 17. from one SDR to another and is generally reported by pipe manufacturers.
What is the weight of HDPE?

What is SDR in HDPE?
SDR is the ratio of the outside. diameter to the wall thickness. For. a specific outside diameter pipe, the. thicker the wall thickness, the lower.
How is SDR calculated?
How can one calculate the value of an SDR? To calculate the value of the SDR in national currency (say, ABC), multiply the four exchange rates of the home country vis-à-vis the basket-currency countries (i.e., ABC/USD, ABC/EUR, ABC/JPY, and ABC/GBP) with the basket values indicated in the above table.
What does SDR 17 mean?
Size Dimension Ratio
SDR stands for Size Dimension Ratio. So you divide the outside diameter of the HDPE piping (in mm) by the SDR, to give you the pipe wall thickness. For example, you could divide 200mm(OD) by 17(SDR 17), giving a wall thickness of 11.7mm. With HDPE piping material, SDR17 gives you a pressure rating of PN10, or 10 bar.
What is the SDR 11 pipe used for?
An SDR-11 means that the outside diameter (OD) of the pipe is eleven times the thickness of the wall. With a high SDR ratio, the pipe wall is thin compared to the pipe diameter. With a low SDR ratio, the pipe wall is thick compared to the pipe diameter. So a high SDR pipe has a low-pressure rating, and low SDR pipe has a high- pressure rating. 1.
What’s the difference between IPS and SDR pipe?
Iron Pipe size pipe has the identical dimensions as iron pipe does. This pipe is commonly referred to as IPS or SDR pipe. The outside diameter of IPS pipe is the controlling dimension. In other words, all 4″ IPS polyethylene pipe will have a 4.500″ outside diameter (OD).
Why is the SDR / Dr ratio important with PE pipe?
Tip: Here are two examples that show why the SDR/DR dimensional ratio is important with PE pipe: 1.
What’s the difference between SDR and sdr-11?
Many PE pipe manufacturers use the SDR method of rating pressure piping. An SDR-11 means that the outside diameter (OD) of the pipe is eleven times the thickness of the wall. With a high SDR ratio, the pipe wall is thin compared to the pipe diameter. With a low SDR ratio, the pipe wall is thick compared to the pipe diameter.
