摘要
在管中掺杂空气和无空气两种情况下,从热塑性HDPE管在试压压力作用下的粘弹性应变特性出发,对试压时压力变化进行研究,分析HDPE管试压时压力变化规律与管道中空气含量及应变的关系,并根据分析结果说明HDPE试压方法和相应对策.
With and without air content in water, the pressure change of HDPE pipe hydraulic test is analyzed to show the relationship between the air content, strain and the pressure,based on the viscous-elastic of HDPE pipe, the result is used to explain the method and measure of HDPE pipe hydraulic test .
