Is There a Connection Between the Application of Stainless Steel Welded Pipes in Nuclear Power and Passivation?

Stainless steel welded pipes are hollow, elongated circular steel materials widely used in industries such as petroleum, chemicals, nuclear power, and healthcare. A TikTok user leave a message, "Is there a connection between the application of stainless steel welded pipes in nuclear power and passivation?"

When selecting materials and manufacturing methods for stainless steel which are used in internal equipment and recirculation system piping in reactors, special attention should be paid to suppressing stress corrosion cracking and reducing the impact of radiation.

Is There a Connection Between the Application of Stainless Steel

In general, to enhance the corrosion resistance of stainless steel welded pipes, two methods are commonly used: passivation and electrolysis. For stainless steel welded pipes applied in nuclear power, corrosion protection typically involves passivation treatment (using stainless steel passivation solution). Passivation is a new process as an alternative to physical rust prevention oil. The principle involves using oxidizing agents in the passivation solution (stainless steel passivation solution) to transform active metal ions on the metal surface into a passive state. This effectively delays metal corrosion. Passivation is a microchemical reaction that does not alter the molecular structure of the material. It merely combines oxygen with active metal elements in the material, producing metal oxide. This oxide layer is in a passive state, acting as a barrier between the metal and the corrosive medium, preventing direct contact and stopping the metal from dissolving, achieving the desired corrosion prevention effect.
