一、前言牺牲阳极法阴极保护是一种古典的保护方法,至今仍有很强的生命力。特别是近几年,随着牺牲阳极应用技术的复甦,它的应用领域已逐渐扩大,已推广应用于油气管道、成品油管道、自来水管道、预应力钢筋混凝土管道、煤气管道、热力管网、罐底保护及电气接地等领域。在应用技术和设计计算方面多套用国外现有经验,我们结合应用技术的需要,对成组阳极埋设的各种方式调整系数进行了探索。本文根据上海、天津、陕西等地现场测量数据对组合牺牲阳极调整系数进行初步分析。
I. Preface Sacrificial Anode Cathodic protection is a classical method of protection and still has strong vitality so far. Especially in recent years, with the application of sacrificial anode recovery, its application has been gradually expanded, has been widely used in oil and gas pipelines, oil pipelines, water pipelines, prestressed concrete pipelines, gas pipelines, heat pipe network , Tank bottom protection and electrical grounding and other fields. In the application of technology and design and calculation of multiple sets of existing foreign experience, we combine the needs of the application technology, grouping the anode buried in various ways to adjust the coefficient were explored. Based on the field measurement data of Shanghai, Tianjin, Shaanxi and other places, the article makes a preliminary analysis of the combined sacrificial anode adjustment coefficient.
