摘要:压力管道是一种特殊承压设备,被广泛应用于运输可燃易爆、有毒、有害气体或液体,具有一定的危险性,在使用的过程中,可能会因管道老化、缺陷等问题导致介质泄漏,进而造成经济损失,甚至人员伤害,因此对压力管道进行全面检验提前发现问题变得尤为重要。压力管道检验常用的方法有测厚、射线、超声等,针对不同介质及运行工况,选择一种或几种的组合,但目前并无详细的检验全过程的介绍。本文主要阐述了压力管道检验的过程,详述不同检验方法的适用性,并对检验过程中存在的问题给出具有可行性的解决方案。

Abstract: Pressure pipeline is a kind of special pressure equipment, which is widely used to transport flammable, explosive, poisonous, harmful gas or liquid, and has certain risk. In the process of use, the pipeline aging, defects and other problems may lead to medium leakage, resulting in economic losses, or even person injuries. Therefore, it is very important to detect the problems in advance through the comprehensive inspection of the pressure pipeline. The commonly used methods of pressure pipeline inspection include thickness measurement, ray and ultrasonic. One or several combinations are selected for different media and operating conditions, but there is no detailed introduction of the whole process of inspection at present. This paper mainly describes the process of pressure pipeline inspection, details the applicability of different inspection methods, and gives feasible solutions to the problems existing in the inspection process.

作為一种特殊的管道设备,压力管道被广泛地应用在化工领域,用于运输具有一定危险性的气体或液体[1]。在管道制作、运输、安装环节可能存在选材不当、运输磕碰、安装不合格等缺陷,尤其是管道中存在的裂缝缺陷对管道的整体质量有很大的影响[2]。管道投用前或短时间运行时无法表现。实际使用工况下,由于压力管道长时间带压运行,且部分管道使用环境恶劣,各种不确定因素会导致压力管道存在泄漏的风险,一旦发生故障,不仅难以保证工业企业的生产效率和质量,且易引发重大的管道泄漏或爆炸灾难[3]。因此,必须对压力管道进行定期检验,以提前发现问题,保障设备平稳运行。本文详细阐述了压力管道检验的过程,详述不同检验方法的适用性,并对检验过程中存在的问题给出可行的解决方案。……
