从研究用于喷灌的涂塑软管温度修正系数的大量试验中发现,测试涂塑软管液压爆破压力时,试样几乎全部为纵向爆破,少量横向爆破则是由于接头连接处抱箍割破所致,并非纵向强度不足而横截面拉断爆破。发现这一现象后,我们对涂塑软管的机理进行了研究和分析,并应用已研究成的涂塑软管温度修正系数,计算在各种不同压力等级 From a large number of tests on the temperature correction coefficient of plastic pipe used in sprinkler irrigation, it is found that when the pressure of plastic pipe is tested, almost all of them are vertical blasting, and a small amount of horizontal blasting is due to the cutting of hoop As a result, the longitudinal strength is not sufficient and the cross-section is pulled off blasting. After discovering this phenomenon, we have studied and analyzed the mechanism of plastic coated hose, and applied the temperature correction factor of plastic hose that has been researched to calculate the difference between different pressure grades
