摘　　要：通过实验测定了S3．2，dn90×en12．3mm规格PP—R管路系统的水锤波速值为390～450m／s，平均波速为425．25m／s。按厚壁管水锤波速计算公式得到的结果为321．33m／s，该值比实测值小24％。因此，计算PP-R管水锤波速的公式有待进一步研究。Based on field tests, the measured wavespeed of water hammer in PP-R pipe in type S3.2,dn90×en12.3 mm polypropylene（PP-R） pipe is between 390 m/s and 450 m/s , and average value is 425.25 m/s. While result calculated by present wavespeed formula of thick pipe is only 321.33 m/s, which is 24% less than the test result. Accordingly the formula calculating the wavespeed of water hammer of PP-R pipe needs to be further studied.
