中图分类号：TH87 文献标识码：B doi：10.3969/j.issn。1674-3407.2013。01.017Development of Silicon Core Pipe Dynamic Friction TesterShao J unj ie，Bao Yuexiang，Fu Yimiao，Chen Min(Zhejiang HuaFeng Pipe Industry Co.，Ltd.Fuyang 311400，Zhejiang，China)Abstract：The principle and the structure of HDPE silicon core pipe dynamic friction tester are in-troduced in this article.A large number of tests are done to decide whether the tester can meetthe testing requirements or not. At last，the conclusion that whether the tester is applicable ornot is puts forward。
