The sequence to master when replacing the gasket of a plate heat exchanger
The use of titanium plate heat exchangers has completely dealt with the corrosion of the equipment. The heat exchange area is 1/4 of the original equipment and the floor area is only about 20% of the original equipment. It can save 20,000-30,000 yuan in annual direct maintenance costs. Annually recyclable, and more importantly, prolong the production cycle and avoid economic losses caused by equipment maintenance and shutdown.
In order to solve the corrosion problem of the heat exchange equipment containing hydrochloric acid oligomer medium, a 4m2 plate heat exchanger with a heat exchange area of BR0.1 was used instead of the heat exchanger with a heat transfer area of 16 square meters for the floating carbon steel shell . device. After using the equipment, it was found that it was corroded at the carbon steel receiving place, and the titanium plate inside the equipment was not corroded.
Remove the used gaskets in the order of gasket replacement of the plate heat exchanger. When removing, be careful not to scratch the gasket groove. Use acetone, methyl ethyl ketone or other ketone solvents to remove residual glue from the gasket. Clean the gasket grooves and gaskets with a clean cloth or cotton yarn. Apply adhesive evenly to the gasket groove. Apply a clean, new gasket to the board. Before using the gasket, it should be placed in a flat, cool, ventilated natural dry solid.
