WebSDR for a 10 inches ASTM D2241 - PVC Pipe with outside diameter 10.750 inches and wall thickness 0.168 inches can be calculated as. SDR = (10.750 in) / (0.168 in) = 64. A SDR 64 means that the outside diameter - D - of the pipe is 64 times the thickness - s - of the wall. with a high SDR ratio the pipe wall is thin compared to the pipe diameter. WebHence Calculated wall thickness (t, mm) = (7800*273.05)/ (2*0.72*359870*1) = 4.10. If the sum of allowances for threading, grooving, corrosion, and erosion and an increase in wall thickness if used as protective measure=0.3 mm. Then nominal wall thickness satisfying requirements for pressure and allowances= 4.1+0.3= 4.4 mm.
