Stainless steel pipes are steel pipes with less diameter (usually ≤4.8mm) of stainless steel. It is mostly used in aviation, electromechanical, instruments, instrumental components and other fields.

1. Chemical corrosion:

Exterior pollution: Oil pollution, dust, acid, alkali, salt, etc. attached to the outside of the workpiece converted into a corrosive medium in certain conditions, chemically respond to certain ingredients in stainless steel tubes, and chemically corrode and rust.

Orthodox scratching: Damage to the passivation film of various scratches, the protection of stainless steel can be reduced, it is easy to respond to chemical medium attacks, and chemically corrode and rust.

Cleaning: After the pickled passivation, the cleaning is not clean.

Second, it is electrochemical corrosion:

Carbon steel pollution: The scratching and corrosive medium of the touch of carbon steel parts form an electrochemical corrosion of the original battery. Cutting: The adhesion and corrosive medium of rusty substances such as residue and splashing constitute the original battery and develop electrochemical corruption.

Baked school: The ingredients in the flame heating area and the gold phase organization have changed and uneven, and the electrochemical corrosion of the original battery is composed of the original battery with the corrosive medium.

Welding: The physical disadvantages and chemical disadvantages of the welding area and the corrosion medium constitute the original battery and develop electrochemical corrosion.

Ingredients: The chemical disadvantages and physical disadvantages of stainless steel raw materials are conducive to forming electrochemical corrosion of the original battery with the corrosive medium.

Pastolation: Purmaking passivation is not good, constitutes an uneven or thinner appearance of the stainless steel appearance passivation film, which is easy to constitute electrochemical corrosion.

Cleaning: The reserved pickled passivation residue and stainless steel produce chemical corrosion of the generics and stainless steel tubes to form electrochemical corrosion.
