Why should the gaskets on both sides of the tube plate be of the same material?
Since the flange fastening bolts on both sides of the tube sheet are the same bolt, the specific pressure applied to the gaskets on both sides of the tube sheet is the same. If the gaskets on both sides of the two sides are made of different materials, it is inevitable that the gasket on one side of the gasket is insufficiently pressed to cause the seal failure or the gasket on the other side is too large to cause the seal to fail. Therefore, the gaskets on both sides of the tube sheet must be Use the same material.
Why does the cooling water heat exchanger produce scale?
Scale is formed by crystallizing dissolved salts in water and attached to the wall of the heat exchanger. It is characterized by being dense and hard, firmly attached, and difficult to remove. Suspended particles in a large amount in water can become seed crystals, and other impurity ions, bacteria, rough metal surfaces, etc. have a strong catalytic effect on the crystallization process, greatly reducing the supersaturation required for crystallization, so the cooling water heat exchanger It is easy to produce scale.
