Stainless steel push-in fittings are widely used in our life. If we need to use it for a long time, what are the anti-corrosion methods for Stainless steel push-in fittings?

Stainless steel push-in fittings are made of metal. There are four main methods for corrosion protection of metal, namely, the nature of the material itself, the environment of use, the interface between the material and the environment, and the plan for improving corrosion. If stainless steel push-in fittings are made from an alloy that does not lack corrosion resistance, it is not practical in economic terms unless there is a special need for it or the appearance of stainless steel push-in fittings is completely isolated from corrosive environmental elements.

In practice, this may not be feasible and can be very difficult. However, most stainless steel push-in fittings programs can not be completely modified, and their protective effects are great, so this method can not solve the problem basically, as long as the metal corrosion interface, that is, the appearance of anti-corrosion treatment is now widely used method.

Corrosion protection of Stainless steel push-in fittings is the application of a protective layer on a metal surface by various methods. Its function is to isolate the metal from the corrosive environment to prevent corrosion or to reduce the contact between the corrosive medium and the metal surface. The intention is to avoid or mitigate corrosion.

The protective cover shall be capable of meeting the following requirements:

1. Corrosion resistance, abrasion resistance, high hardness,

2. Compact structure, no defects, small pores.

3. Strong adhesion to the base material.

4. Evenly distributed and thick.

The protective layers of Stainless steel push-in fittings are usually divided into two types: metallic coating and non-metallic coating. The metal coating is the use of strong corrosion resistance of the metal or alloy on the surface of the corrosion-prone metal to form a protective layer. This coating is also known as electroplating.

There are many methods and varieties of metal coating. Of these, electroplating is the most commonly used method, followed by molten metal immersion plating (hot dip plating and chemical surface treatment. Non-metallic coating refers to the use of organic polymer materials, such as paint and inorganic materials), for example, ceramics form a protective layer on the surface of stainless steel push-in fittings or parts that insulates the base material from environmental media and avoids corrosion of stainless steel push-in fittings due to contact with standard stainless steel media.
