引言加热系统的工作寿命和可靠性与加热管道外表面的适当的防腐措施密切相关。管道失效会引起部份或全部供热中断和高额维修费用。波兰,在加热管道外表面涂覆多层抗蚀层,其构成是: 一层或两层抗腐蚀油漆(用以防止管道在贮存、安装和工作期间发生腐蚀); 绝热层(主要由玄武岩、火山岩或玻璃纤维面罩构成); 外覆盖层,如具有铝芯、石棉-粘合剂衬里的柏油毡。使用期间,加热管道的外表面裸露于以高相对
Introduction The working life and reliability of the heating system are closely related to the proper corrosion protection of the outer surface of the heating pipe. Failure of the pipeline will cause some or all of the heating disruption and high maintenance costs. Poland, the outer surface of the heating pipe is coated with a multilayer of corrosion protection consisting of one or two layers of anti-corrosion paint (to prevent corrosion of the pipe during storage, installation and operation), thermal insulation (mainly consisting of basalt, Volcanic rocks or fiberglass masks); outer coverings such as asphalt felt with an aluminum core, asbestos-adhesive backing. During use, the outer surface of the heating pipe is exposed to high relative
