What is the difference between DR14 and DR18 pipe?
DR18 pipe shall have a pressure class of 1,620 kPa (235 psi). DR14 pipe shall have a pressure class of 2,100 kPa (305 psi).
What is the difference between C900 and C905 pipe?
C900 pipe is delivered in standard laying lengths of 20 feet +/- 1 Inch. C900 pipe is also suitable for use in waste water force main services. C905 is a comparable standard for potable water PVC pressure pipe, designed for pipe and fittings with nominal sizes over 12 inches.
What does SDR 9 mean?
SDR is defined as the ratio of the nominal outside diameter to the nominal wall thickness. It is common to use the SDR as a method of pressure rating pipes. Therefore a higher SDR indicates a thinner-walled pipe at any given diameter. Common SDR’s are : 7.4, 9, 11, 13.6, and 17.
What does dr11 mean?
This means that two pipes with the same OD but different DR numbers would have different wall thicknesses. For example, a 14” OD pipe with a wall thickness of 1.273 inches would have a DR of 11, while a 14” pipe with a wall thickness of 0.824 would have a DR of 17.
What class is C900 PVC?
PVC compound meets ASTM D 1784, cell class 12454. Meets AWWA C900.
What is C900 pipe made of?
polyvinyl Chloride (pvC)
this pipe shall meet the require- ments of AWWA standard C900, “polyvinyl Chloride (pvC) Water distribution pipe.” All pipe shall be made from quality pvC resin, compounded to provide physical and mechanical properties that equal or exceed cell class 12454 as defined in AstM d1784.
What is the difference between SDR11 and sdr17?
The strength is greater for the lower SDR value that represents thicker pipe wall thickness; making SDR 11 stronger than SDR 17. However, in the case of ring deflection, the pipe strength is not a function of SDR, but a function of another parameter called allowable ring deflection.
What is the difference between dr11 and SDR11?
The key difference between them is that DR is used for any number, while SDR is used for a particular series of numbers ( 17, 11, 9, 7, etc.) This series is based on a geometric progression pattern and was developed by Charles Renard, a French engineer.
What is SDR17 pipe?
SDR17 HDPE Pipe (High Density Polyethylene Pipe)
Is HDPE pipe safe for drinking water?
By and large, HDPE is reported to be one of the “good” plastics, safe for use with food and water.
What pressure rating is SDR11?
16 bar
SDR11 stands for the size dimension ratio of 11. You must divide the OD(mm) of the HDPE piping by the SDR, to give you the pipe wall thickness. E.g. divide 180mm(OD) by 11, giving a wall thickness of 16.4mm. With HDPE piping, SDR 11 gives you a pressure rating of PN16, or 16 bar.
What type of pipe is SDR?
SDR stands for Standard Dimension Ratio. SDR is the ratio of the outer diameter to the thickness of the PE pipe, which is one of the characteristics of the Polyethylene pipe, and the pipes can be sorted according to the standard tables accordingly.
