管道试压主要目的是检查压力管道系统及连接部位的工程质量，保证管道系统的承压强度和严密性，也是决定管道能否安全运行的重要依据。根据某油品预加氢装置的高压换热器及其连接管道系统整体打压的要求，从设计的角度，通过对其设计参数的分析，要求主专业统筹考虑，协调好相关专业的设计要求条件，参照相关标准规范，选择合适的试验压力，满足设备与管道一起整体水压试验要求，满足施工单位编制试压包的依据需要，避免因试压设计方案考虑不周使工期延误、施工返工等，为以后的同类设计问题提供借鉴和参考。

The objective of pressure test for piping is to exam the quality of pressure piping system and its connection with other equipment so as to ensure the strength of piping system and its compactness. The result of pressure test is also the important basis for determining if the performance of piping system is safe. In this article, with the requirements in integral pressure test for high pressure heat exchanger and its connected piping in one pre-hydrogenation plant, from design point and based on the analysis of design parameters, it was demanded that main specialty should take the integration of all factors into account, coordinate the design requests from relevant specialties and refer correlative codes and standards, then proper test pressure should be selected, with which the requirement of integral hydrostatic test for equipment and piping can be reached, the requirements from the party of construction in compiling testing documents be met. In this way, the incidents of delay in finishing construction can be avoided. What presented herein can be referenced in the similar engineering later.
