Discussion on Installation Standards and Construction Risks of Process Piping in Petrochemical Engineering
石油化工工程中工艺管道安装标准及施工风险探讨

摘要

在石油化工工程中，工艺管道的主要功能为输送物料、转换能量，管道的安装质量会直接影响到系统整体的运行 安全。但伴随装置的建设规模逐渐增大，工艺管道安装施工面临多重风险。因此，本文将首先分析石油化工工程中工 艺管道的安装标准，包含管道预制组对、焊接工艺评定、无损检测与热处理、压力试验与吹洗等，在此基础上，从材 料预制、安装作业、试验试压等几个方面识别施工中的主要风险，最后提出更显管控策略，希望进一步提高石油化工 工程中工艺管道安装施工规范性、安全性。

Abstract

 In petrochemical engineering, process piping is mainly used for material transportation and energy conversion, and its installation quality directly affects the overall operational safety of the system. With the continuous expansion of plant construction scale, process piping installation faces multiple construction risks. Therefore, this paper first analyzes the installation standards for process piping in petrochemical engineering, including pipe prefabrication and assembly, welding procedure qualification, nondestructive testing and heat treatment, pressure testing, and purging. On this basis, the main construction risks are identified from several aspects, such as material prefabrication, installation operations, and pressure testing. Finally, corresponding risk control strategies are proposed, with the aim of further improving the standardization and safety of process piping installation in petrochemical engineering.
