Equipment Cleaning - Chemical Cleaning Chemical cleaning technology includes the measurement of dirt, dirt dissolution testing, process system design, cleaning quality monitoring, assessment of cleansing effect and treatment of waste water discharged. The scope of chemical cleaning projects: Various types of pressure vessels, and boiler cleaning; various types of heat exchanger equipment cleaning; all types of recirculating cooling water system cleaning; equipment degreasing, descaling and passivation; system and equipment pre-cleaning before usage; petroleum, chemical, food, paper industry equipment cleaning; all kinds of large-scale motor, compressor and cooling water system cleaning; the outer surface of various metal devices cleaning; central air-conditioning system cleaning; various large, medium and small chemical tank, reactor cleaning. Comparison before and after circulating water system cleaning: Air cooled heat exchangers outside appearance (Aluminum) limescale Before cleaning   After cleaning Cleaning operation construction site Before cleaning   After cleaning         Equipment Cleaning - High-pressure Water Jet Cleaning High-pressure water jet cleaning is a cleaning technique that is becoming popular in recent years. High-pressure water jet is to pressure tap water to hundreds and even thousands of atmospheric pressure through high-pressure pump, and then use a special nozzle to inject the high energy water current. The injection currents have enormous impact, capable of cutting steel, cleaning sand casting and removing metal rust. The currents can also remove salt, alkali, dirt on wall surface and all kinds of plug material in the pipelines.   Silicate fouling of heat exchanger cleaning effect (comparison before and after)   The plant leaf cleaning effect (comparison before and after)   Operation of high pressure cleaning nozzle Equipments that by cleaned by high-pressure water jet cleaning 1. Various specifications from top to bottom of water pipelines. 2. A variety of heat exchangers. 3. Various types of boilers. 4. Heating systems. 5. Various large buildings.
