Heat exchanger ( heat exchanger ) are commonly used in the petrochemical industry, has a certain importance. Normal safe operation of the heat exchanger directly affect the company´s production . Therefore, we must do daily heat exchanger maintenance work . How to solve the problem of corrosion of the heat exchanger ? According to the corrosion factor of the heat exchanger , take a relatively reliable anti -corrosion measures .
1 , in the purchase of heat transfer equipment, heat exchangers need to consider whether the material reliable, compressive strength, resistance to corrosion ;
2 , the heat exchanger device designed to prevent direct fluid tube erosion , scour bundles to be installed on board ;
3 , for the implementation of the heat exchanger corrosion protection , corrosion resistance and anti- permeability, thermal conductivity, ability to scale better anti-corrosion coating , play a protective role .
4 , because the loop contains too much water of impurities , sediment , and we have to deal with water quality ; make clear the scale, slime , bacteria and other dirt cycle greatly extended.
5 , the welding seam as well so to avoid precipitation caused by corrosion and liquid residues ;
6 , to avoid damage to the heat exchanger installed equipment ; After installing a heat exchanger cleaning process is completed in a timely manner ; 7, in the device during operation, the production process to ensure strict compliance . When feeding, ensure that the materials used are correct ; 8 , disable heat exchanger device, check the device to do maintenance work , such as the presence or absence of heat exchanger equipment fouling , clogging and corrosion ; regular inspections to clean up and protect the equipment surface from corrosion.
9 , according to the clogging of the heat exchanger fouling , cleaning heat treatment ;
9 , when the reservoir caused by the heat exchanger equipment required to prevent atmospheric corrosion , heat exchanger equipment in good condition to ensure a clean surface . |
