随着社会主义建设事业的蓬勃发展,各种用途的地下管道与日俱增.在长期的生产和生活实践中,人们更加认清了防腐蚀的重要性,因而有力地促进了地下管道的阴极保护设计工作.在强制电流阴极保护的设计中,主要一环为辅助阳极地床的设计,其设计是否合理直接影响阴极保护设计的经济效益.本文仅就阳极地床设计中的一些问题谈点看法. 一、阳极地床位置的选择阳极地床相对管道的位置将决定保护电位分布的均匀程度.阳极地床相对管道的距离越远,电位分布越均匀.但无限制地拉大距离将会增加阳极引线的电阻并增加投资. 在选择阳极地床位置时,应考虑到周围
With the vigorous development of the socialist construction, underground pipelines of various uses have been increasing day by day. In the long-term production and daily life practice, people are more aware of the importance of anti-corrosion and effectively promoted the design of cathodic protection for underground pipelines In the design of forced current cathodic protection, the main part is the design of ancillary anode bed, and its design is reasonable and directly affects the economic benefits of cathodic protection design.This paper only discusses some problems in the design of anode bed. The choice of anode bed position The location of the anode bed relative to the pipe will determine the uniformity of the protection potential distribution.The more distant the anode bed is from the pipe, the more uniform the potential distribution.But unlimitedly widening the distance will increase the anode lead Of the resistance and increase investment in the choice of anode bed position, should take into account the surrounding
