What does C900 mean?
What does C900 mean?
C900 is the AWWA standard for cast-iron-pipe-equivalent outside diameter polyvinyl chloride (PVC) pressure pipe and fabricated fittings for potable water transmission and distribution, covering nominal pipe sizes from 4 inches through 12 inches.
What does Dr 18 mean?
Dimension Ratio
Dimension Ratio The pipe DR is defined to be the ratio of the pipe outside diameter to the pipe minimum wall thickness. For example, a DR 18 C900 pipe would have an outside diameter equal to 18 times its wall thickness.
What is the OD of 12 C900?
13.20″
| Nominal Pipe Size (in.) | Pipe Outside diameter (in.) | DR-25 (165 PSI) |
|---|---|---|
| 6″ | 6.90″ | 3.90 lbs. |
| 8″ | 9.05″ | 6.69 lbs. |
| 10″ | 11.10″ | 10.11 lbs. |
| 12″ | 13.20″ | 14.32 lbs. |
What class is C900 pipe?
class 200
GENERAL REQUIREMENTS C900 PVC pipe installed in the SAWS High Pressure Zone shall be class 200 (DR 14) having a sustained pressure requirement of 650 psi (ASTM D1598) and a minimum burst pressure of 985 psi (ASTM D1599).
What is C900 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 PVC Dr?
The terms “dimension ratio” and “standard dimension ratio” are widely used in the PVC pipe industry. The term DR became widely used, in 1975, with the publication of AWWA C900, which governs production of small diameter PVC pressure pipe. AWWA allowed the desired pressure capacity to dictate wall thickness.
Who makes C900 pipe?
Diamond Plastics
Diamond Plastics manufactures 4” through 12” cast iron O.D. PVC pressure pipe in accordance with AWWA C900, Standard for Polyvinyl Chloride (PVC) Pressure Pipe and Fabricated Fittings, 4 In.
What is C900 pipe made of?
What is the pressure class of a C900 pipe?
C900’s pipe wall is extremely smooth and energy-efficient. It has a Hazen-Williams coefficient of C=150. Pressure Class. PWPipe offers a choice of three pressure classes (100, 150, and 200) which can be used where operating pressures do not exceed the pressure class plus surge allowances.
What are the pressure requirements for C900 bell sections?
Each bell section meets the same pressure capacity requirements as the pipe. Standard laying lengths are 20 feet (plus or minus 1 inch). Each standard and random length of C900 is tested to four times the pressure class of the pipe, for a minimum of five seconds. The integral bell is tested with the pipe.
What is the flow coefficient of the C900?
An extremely smooth inner surfacegives C900 a Hazen-Williams flow coefficient of C=150. This means lessburden on pumps and reducedpumping costs, because there’s lessfriction between moving water andpipe walls.
How do you calculate friction loss in pipe?
By observation, the friction loss in pipe is roughly proportional to the square of the flow rate in most engineering flows (fully developed, turbulent pipe flow). The most common equation used to calculate pressure loss in pipe, tube or duct is the Darcy–Weisbach equation.
