Do you know how to deal with the surface grease generated during the production of stainless steel heat exchange tubes more effectively?
Mingxin Stainless Steel gives the answer below.
(1) The grease generated on the surface of the stainless steel heat exchange tube is degreased with nitric acid of border defense certificate 12-15 (calculated by volume) at 40-60°C for 2-4 hours.
(2) When placing the stainless steel heat exchange tubes into the water tank, pay attention to the placement position to avoid air in the tubes.
(3) During the soaking process, the stainless steel heat exchange tube should be moved up and down or rotated back and forth, so that the solution in the cavity is constantly changing and the cleaning effect is improved. If necessary, the stainless steel heat exchange tube should be taken out and cleaned with water before soaking.
(4) Chemical degreasing should be carried out in the immersion tank. The degreasing tank is made of steel plate, and the inner wall is laid with PVC or polyethylene.
(5) Chemical degreasing until the surface of the fitting is completely saturated with water.
According to the above method, the surface grease of the stainless steel heat exchange tube can be removed.
