Minimize contact between acidic substances like soy sauce and oil stains with stainless steel heat exchange tubes in daily life, as they can easily undergo a chemical reaction, potentially leading to rust on the air-to-air heat exchange tubes.

Before installing the air-to-water heat exchanger tubes, apply a layer of vegetable oil to the outer surface of the water pipes and then slightly dry it with a low flame. This method is intended to extend the service life of the air-to-water heat exchanger tubes and also makes cleaning easier.

If the outer surface of the heat exchange tube shows signs of rust, it's important to apply a specialized stainless steel wax for rust removal promptly. After applying the wax and allowing it to set for a while, you can proceed with sanding and cleaning. Once the wax is thoroughly cleaned off, the outer surface of the heat exchange tube will regain its luster.

In daily life, try to avoid using pointed objects to collide with the stainless steel heat exchanger tubes.

When transporting stainless steel heat exchanger tubes, it is essential to wrap and secure the pipes properly to prevent them from colliding with each other or coming into contact with sharp objects, which can easily cause dents on the surface of the pipes, compromising their appearance.

Once the outer layer of the stainless steel heat exchange tube is scratched, apply a small amount of stainless steel care agent to a dry towel, then wipe the scratched area. After cleaning, gently sand the scratch with an abrasive wheel until it disappears.

To achieve a glossy finish on the exterior of stainless steel heat exchange tubes, simply apply stainless steel cleaner with a soft cloth. The pipe will instantly shine. However, this method should not be used frequently, as it may eventually dull the original luster of the pipe.
