Analysis of Some Standards on the Differences of Hydraulic Tests of Hot - water Heat Supply Pipe Network

管道试验压力值的大小有多种确定方法。不仅试验压力大小差别较大,而且造成工程投资的差异也较大。本文通过理论分析和对各规范的对比,给出了按分段最大工作压力作为基数的一种经济合理、技术可靠的试压值的确定方法。

The pressure in pipe test is measured by using many different methods, so the difference of the volume of the test pressure is bigger and the difference of the engineering investment is bigger, too. Through theoretical analysis and comparison of each standard, this paper gives a rational and reliable method to determine the test pressure volume that takes the maximum sectional working pressure as the cardinal number.
