Plate heat exchanger plates are specially used in plate heat exchangers to isolate the medium and conduct heat exchange. They are an important part of the plate heat exchanger. Its main materials are stainless steel (SUS304.316), titanium and titanium palladium (Ti, Ti-Pd), 20Cr, 18Ni, 6Mo (254SMO), alloy (C276), copper (H68). The quality of the plates of the plate heat exchanger affects the overall performance and working conditions of the plate heat exchanger. What material is the plate heat exchanger made of? Some plates are titanium alloy, and some are stainless steel. So how to distinguish stainless steel and titanium alloy plate heat exchangers? We can consider the color, weight and performance of the plate.
The general color of the titanium plate is a bit dark, and the stainless steel plate is whitish. Titanium plates are lighter than stainless steel plates.
It can be concluded from the density that the titanium plate is much lighter than stainless steel, the gloss is better than stainless steel, and it can be distinguished by nitric acid foam. Titanium does not react, and a strong reaction occurs when stainless steel is put down.
Titanium can make gray-black marks on ceramic tiles, but stainless steel can't make marks. The corrosion inhibitor with chromate as a secondary component is rarely used in cooling water. The chromate ion of plate heat exchanger is a (process) gram preparation. When it is combined with a suitable gram preparation, it can lose Satisfactory and economical anti-corrosion results.
