The heat exchange pressure vessel is mainly a pressure vessel used to complete the heat exchange of the medium. Proper maintenance of the heat exchange pressure vessel can keep the vessel in good condition, improve work efficiency and extend the service life of the vessel. Now I will briefly introduce the maintenance of heat exchange pressure vessels, hoping to help you.
Keep the anti-corrosion layer intact. Containers where the working medium has a corrosive effect on the material often use an anti-corrosion layer to prevent the medium from corroding the vessel wall, such as painting, spraying or electroplating, lining, etc. If the anti-corrosion layer is damaged, the working medium will directly contact the wall and cause corrosion, so regular inspections should be made to keep the anti-corrosion layer intact.
Eliminate factors that cause corrosion. Some working media will corrode the material of the container only under certain specific conditions. Therefore, efforts should be made to eliminate such conditions that can cause corrosion, especially stress corrosion. For example, carbon monoxide gas may cause stress corrosion on steel containers only if it contains moisture. Measures such as dry operation and filtration should be adopted as much as possible.
Eliminate leakage, bubbling, dripping and leaking of containers and always keep the containers in good condition. Running, popping, dripping, and leaking not only waste raw materials and energy and pollute the working environment, but also often cause serious corrosion of equipment and damage to containers.
Enhance container maintenance during outage. Containers that are out of service for a long time or temporarily should be maintained more intensively. Decommissioned containers must have the internal media removed and corrosive media must undergo technical treatment such as discharge, replacement, and cleaning. Pay attention to prevent corrosive media from accumulating in the dead corners of the container. The container should always be kept dry and clean to prevent atmospheric corrosion. Tests have proven that the atmosphere will corrode steel only when there is dust and dirt on the surface of the steel in humid conditions.
Always keep containers in good condition. All safety devices and measuring instruments on the container should be adjusted and calibrated regularly to keep them sensitive and accurate. The accessories and parts of the container must be kept complete and intact. Containers with incomplete connecting fasteners are prohibited from being put into operation.
The above is the knowledge I provided about the maintenance of heat exchange pressure vessels. I hope that my content can give you a certain understanding of the maintenance of heat exchange pressure vessels and increase your awareness. In short, regular maintenance of the product is the best way to save yourself the cost of living.
