Question: What are the methods for cleaning fouling from heat exchangers? Answer: 1) Mechanical cleaning method: Cleaning is carried out using manual or mechanical tools such as shovels and brushes, with assistance from compressed air, high-pressure water, and steam for further cleaning. 2) Flushing method: It is divided into counterflow flushing and high-pressure water flushing. 3) Chemical descaling: Different solvents are used for cleaning depending on the nature of the scale. 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) Mechanical descaling method； 2) Flushing method ； 3) Chemical descaling.
1). Mechanical descaling method. Cleaning is carried out using manual or mechanical methods such as shovels and brushes, with secondary cleaning aided by compressed air, high-pressure water, and steam. 2). Flushing method. It is divided into reverse flow flushing and high-pressure water flushing. 3). Chemical descaling. Depending on the properties of the scaling substance, different solvents are used for cleaning.
