The approximate wave celerities for HDPE pipes are as follows: SDR WE CELERITY - M/S 33 190 26 215 21 242 17 270 13.6 307 11 349 9 395 7.4 450 It is important to note that the pressure increase due to water hammer in a particular class of pipe is a Puhui Pipe manufacturer in China
For PE pipes, a dimensionless nuer is also defined, which is the ratio of the pipe diameter to the thickness of the pipe, which is referred to as the SDR. For example, for a 110 mm PE pipe with a pressure of 4 times made of PE80 materials, weighing 1.17 kg, it is SDR33, and for an PE pipe with a diameter of 110 mm made of PE80, weighting 1.77 kg, it is SDR21.
Certain DRs that meet an ASTM International specified nuer series (32.5, 26, 21, 17, 13.5, 11, 9 and 7.3) are referred to as Standard Dimension Ratios, SDR. There is approximately 25% difference in minimum wall thickness between each SDR.
SDR pipe : "Standard Dimensional Ratio" The SDR pipe is the "Standard Dimensional Ratio" and refers to the geometry of the pipe.SDR is defined as the ratio of the nominal outside diameter to the nominal wall thickness. SDR = dn/en Where dn is the nominal outside diameter of the pipe and en is the nominal (minimum) wall thickness of the pipe.
