一、给水管道泄漏原因1.室内给水管道漏水或渗水的原因:(1)管道接头因长期锈蚀,螺纹受损,法兰垫失修破损造成漏水;(2)由于室内管道明装,长期受外界环境腐蚀促使个别管段壁厚减薄以致破裂而渗漏;(3)管道附件与管子连接处由于材料的不同发生电化学腐蚀而渗漏;(4)管件丝扣连接未拧紧造成渗漏;(5)管道对焊焊缝处未焊牢或有砂眼而泄漏;(6)天长日久断裂而渗漏等。2.埋地给水管道漏水或渗水原因:(1)接头不严渗漏;(2)外部载荷增加引起局部管道断裂造成渗漏;(3)管道基础下沉而断裂形成泄漏;(4)管道受到地面腐蚀液体浸蚀破坏而渗漏;(5)树本等生物根系日益长大,使管道受外力的作用造成破坏而渗漏;(6)管道本身质量问题形
I. Leakage of water supply pipes 1. Reasons for water leakage or water seepage in indoor water supply pipes: (1) The pipe joints are rusted for a long time, the threads are damaged, and the flange gaskets are damaged due to disrepair and damage; (2) The interior pipes are exposed for a long time The environmental corrosion causes the wall thickness of individual pipe sections to be thinned to cause cracking and leakage. (3) The pipe fittings and pipe joints leak due to electrochemical corrosion of the materials. (4) Pipe fittings are not tightened due to screw connection; ( 5) Pipes butt welds are not welded or leaking with trachoma; (6) Long days of breakage and leakage. 2. Causes of leakage or seepage of water in buried water supply pipelines: (1) leaky joints; (2) leakage caused by partial pipeline rupture caused by an increase in external loads; (3) leaking of pipeline foundations and fractures; (4) pipelines Leakage caused by erosion and erosion of ground etching liquids; (5) Biological roots such as trees grow up, causing the pipeline to be damaged and leaked by the action of external forces; (6) Quality problems of the pipeline itself
