Heat pipe heat exchangers have the characteristics of high heat exchange efficiency, uniform temperature, and can exchange heat under small temperature difference conditions, and have been widely used in engineering. Most of the heat exchange equipment used in chemical production equipment is tubular heat exchangers. After a period of operation, the heat transfer effect of the equipment deteriorates due to impurities, scale, etc. in the materials. In order to restore its heat transfer effect, regular inspections are required. The heat exchanger tube side is cleaned with high-pressure water.

High-pressure water cleaning uses a plunger pump driven by a motor, diesel engine, etc. to pressurize it to high pressure, and then sprays it out from a high-pressure spray gun to complete the cleaning. The jet high-pressure water sprayed out by the spray gun has huge impact energy, and the pressure reaches more than 500 bar. Complete different types of cleaning and removal tasks. Using high-pressure water to clean petrochemical equipment can better maintain the performance of the equipment. It is widely used in internal cleaning work during the maintenance of petrochemical production equipment, which can improve the production capacity of the equipment.

Safety measures: First make sure staff have received the necessary safety training and are wearing appropriate personal protective equipment such as goggles, gloves and earmuffs. The operation of pressure washers also requires special care to avoid injury to personnel from the high-pressure water sprayed.

High-pressure cleaning: Use a high-pressure cleaning machine to spray high-pressure water at an appropriate angle and spray intensity onto the internal and external surfaces of the heat exchanger. This helps strip away dirt inside and outside the tube. Keep a certain distance when cleaning to avoid damaging the pipes or increasing risks during the cleaning process.

Inspection and re-inspection: After cleaning is complete, inspect the heat exchanger to make sure dirt has been removed. Sometimes multiple washes are needed to completely remove stubborn dirt.
