The application of heat exchangers in our production and life is very extensive, but if there is only one type of heat exchanger, it will certainly not be able to meet all our needs, so the brand of heat exchangers has become diverse Diversified

Straight tube heat exchanger

Straight tube heat exchanger is the most widely used heat exchanger in chemical and alcohol production. It is mainly composed of shell, tube sheet, heat exchange tube, head, baffle and so on. The required materials can be made of ordinary carbon steel, copper, or stainless steel.

Traditionally, we use water to test the leak of the heat exchanger, that is, inject water into the heat exchanger, fill the water, and then use the pump to press the water in the heat exchanger to make it reach a certain pressure for heat exchange. Check for leaks. After the leak check is completed, mark and release the pressure and drain, then plug the leak. If the heat exchanger is large and the leakage is serious, the leakage will occur when the water pressure is low, and the water has to be drained to plug the leak. After the plugging is completed, the water is filled and the pressure is charged to test the leak, which is repeated to increase the maintenance time of the heat exchanger. . After the straight tube heat exchanger leaks, nitrogen gas is used to charge and leak test, which is relatively fast. When nitrogen is used to plug the heat exchanger for hot work, there is no need to perform replacement treatment, saving time for maintenance and leakage elimination.

A high-efficiency environmentally friendly cleaning agent can be used to avoid the above situation. It has the characteristics of high efficiency, environmental protection, safety, and no corrosion. It not only has a good cleaning effect but also has no corrosion to the equipment, and can ensure the long-term use of the air compressor. Cleaning agent (specially added wetting agent and penetrating agent, can effectively remove the most stubborn scale (calcium carbonate), rust, grease, slime and other sediments generated in the water equipment, while not harming the human body, It will not cause other harmful reactions such as corrosion, pitting, oxidation, etc. on steel, copper, nickel, titanium, rubber, plastic, fiber, glass, ceramic and other materials, which can greatly extend the service life of the equipment. When using our straight tube type In addition to scientific and reasonable use of heat exchangers, regular cleaning and maintenance are also important
