地热水输水管道的选型及安装技术的探讨

摘要

With the implementation of the national policy of energy saving and emission reduction, local thermal heating and hot water units also start to reduce costs and increase efficiency. Because the tubing of traditional water pipe is carbon steel and the hot water has more serious corrosion to the pipes, so network maintenance costs are increasing, and it is imperative to choose new corrosion resistant pipe. This article starts with the analysis of corrosion mechanism of geothermal water on the steel pipe, and discusses the ways to select the new pipe material with temperature resistance feature according to actual situation of Bohai Petroleum Hydro Service Company.%　　随着国家节能减排政策的实施，各地热供暖及地热供水单位也在降本增效，由于传统的输水管道采用碳钢管材，而地热水对管道的腐蚀较为严重，造成管网维护费用增大，这样输水管道选用新型抗腐蚀管材势在必行。文章从分析地热水对钢管的腐蚀机理入手，根据渤海石油水电公司实际情况对输送热水的耐温新型管材如何选用及施工方法进行探讨。
