       无论是用在什么行业里的设备一般正常投入使用前都会进行管道的压力试验和管道涂漆。那么管道的压力试验和管道涂漆要符合什么要求呢?

        一、管道的压力试验,应符合下列要求∶

       1、压力试验应在管路冲洗合格后进行;

2、管道的实验压力和实验介质应该符合下表规定

系统名称

实验压力(MPa)

实验介质

液压系统滑动轴承的静压供油系统

系统工作压力(MPa)

≤16

1.5p

 

工作介质

 

 

>16-31.5

1.25p

 

 

 

>31.5

1.15p

 

气动系统、油雾润滑系统中的压缩空气管道和油雾管道

1.15p

压缩空气

润滑油系统、双线式润滑脂系统

1.25p

       3试压时应先缓慢升压至工作压力检查管道无异常后,再升到试验压力,应保持压力10min,然后降至工作压力,检查焊缝、接口和密封处等,均不得有渗漏、变形现象。


       4、液压系统压力试验时,应将系统内的泵、伺服阀、比例阀、压力传感器、压力继电器和蓄能器脱开。


        二、管道的涂漆,应符合下列要求∶

管道涂漆


       1.管道涂防锈漆前,应除净管道外壁的铁锈、焊渣、油垢及水分等;


       2.涂漆工作宜在5~40℃的环境温度下进行,涂漆后宜自然干燥;未干燥前应采取防冻、防雨、防污、防尘措施;


       3.管道的涂漆颜色和涂层厚度应符合设计规定;涂层应均匀、完整,无损坏和漏涂。

管道涂漆



           三、图层应附着牢固,并应无剥落、皱纹、气泡、针孔等缺陷
