Answer: (1) Sweep out the residues, rust, and other debris remaining inside the pipeline to ensure its smooth operation. (2) Conduct a preliminary pressure test on the pipeline equipment to check for leaks in the equipment, pipelines, valves, and flanges, as well as to determine whether there are any blind plates or loose parts within the pipelines. (3) Be familiar with the process. http://bbs.hcbbs.com/static/image/hrline/4.gif The petrochemical deep processing edition – the event to share pictures of chemical equipment has started!

1. Sweep away the residues, rust, and other debris remaining inside the pipeline to ensure its smooth operation. Conduct a preliminary pressure test on the 2 pairs of pipeline equipment to check for leaks in the equipment, pipelines, valves, and flanges, as well as to determine whether there are any blind plates or loose parts within the pipelines. 3 Be familiar with the process.
When the unit is shut down for maintenance or is started up for the first time, steam is used for purging in order to remove rust and dirt from the pipelines, thereby preventing blockages in the valves
Conduct pressure testing and leak detection, replace oxygen in the system, and clean out any debris from the equipment and piping systems.
First, the tower is purged, which removes rust and slag from inside the tower as well as the pipelines, so that the final product can meet the required standards! Second, test the airtightness of towers and pipelines to prevent leaks after feeding, especially for flammable and explosive finished products, which are even more difficult to weld properly!
