管道管道pipeline用管子、管子联接件(管件)和阀门等联接成的用于输送气体、液体或带固体颗粒流体的装置。通常，流体经鼓风机、压缩机、泵和锅炉等增压后，从管道的高压处流向低压处，也可利用流体自身的压力或重力输送。管道广泛应用于给水、排水、供热、供气、长距离输送石油和天然气、农业灌溉、水力工程和各种工业装置中。马来西亚科兰港火电站冷却水取水管道管子断面通常为圆形，也有制成非圆形截面的异形管。制造管子的材料有钢、铁、铜等金属和陶瓷、塑料、橡胶等非金属以及复合材料等。管子联接件主要是为了满足管道布置和装配的各种要求，如接长管道、转向、分支和改变管径等。按联接形式分螺纹管件、法兰管件、支承管件和焊接管件等。阀门的作用是控制流体流量、压力和流向。管道的管径是最重要的设计参数。当流体的流量已知时，管径的大小取决于允许的流速或允许的摩擦阻力(压力降)。流速大时管径小，但压力降值增加。因而流速大时可节省管道基建投资，但泵和压缩机等动力设备的运行能耗增大。设计管径时应综合考虑建设投资、运行费用和其他技术因素。通常城市里的给水、排水、供热、供气（煤气、天然气、液化石油气等）的管道的干线和长距离的输气输油管道大多埋在地下，而工厂里的工艺管道为便于操作和维修多设在地上。管道敷设时，需要考虑的问题有通行、支承、坡度和排液排气、补偿、保温与加热、防腐与清洗、识别与涂漆、安全等。
