Ppt Pvc Pressure Pipe Class Selection The Sustainable Solution Pvc pressure pipeclass selectionthe sustainable solution. pressure rated design hydrostatic design stress (s) s = hdb x service factor hdb for pvc is 4000 psi for water pipe compounds for hdpe hdb = 1600 psi service factor = 0.5 (defined in appendix of astm d2241) service factor = 1 factor of safety (2.0) for pvc s = 4000 x 0.5 = 2000 psi for hdpe s = 1600 x 0.5 = 800 psi. Large diameter pvc pressure pipe the sustainable solution. enr top 20 innovations. history of pvc pressure pipe standards development. astm d1785 published in 1960 astm d2241 published in 1964 awwa c900 published in 1975 astm d2241 includes 14” 36” in 1984 slideshow 1989698 by inge.
Ppt Pvc Pressure Pipe Class Selection The Sustainable Solution The c900 standard defines the pressure class (pc) as “the design capacity to resist working pressure up to 73°f sustained operating temperature.”. thus, the pc is the pvc pipe’s long term pressure capacity. calculation: the pc is determined by dividing the long term pressure strength by a 2.0 safety factor. Uni pub 09 17 21 installation guide for pvc pressure pipe. this document has been developed by the uni bell pvc pipe association for use as a field installation guide. general information regarding the correct installation of gasketed joint pvc pressure pipe is included. slideshow 9061236 by unibell. Sustainable solutions corporation the pvc pipe lca was subject to critical review from an international panel of experts on life cycle assessment. based on the results from the lca on pvc pipe, pvc pipe provides both environmental and economic advantages to solving the water and sewer infrastructure needs for utilities and municipal projects. The only iso compliant, peer reviewed, industry wide epd for water and sewer pipe in north america. benchmarks the impacts of pvc pipe products across their life cycles. fully transparent and certified by nsf international as an industry best practice. verified lca conformity to product category rule and iso 14025.

The graphical procedure is demonstrated in figure 2. using the charts in appendix a, draw a vertical line from the pressure range on the x axis and a horizontal line from the number of cycles on the y axis. find the intersection of these two lines and read off the pipe pressure class that bounds this region. Stopping a flow that had a velocity of 8 fps will cause a pressure surge of 139 psi in an 12” dr18 pvc pipe. the working pressure of the pvc pipe should be limited to 96 psi (235 psi 139 psi =96 psi). the manufacturer’s published pressure class for a pe4710 dr 17 pipe is 125 psi. the allowable total pressure during.
