Qu'est-ce qu'un coude en acier inoxydable?

Le coude en acier inoxydable est un raccord de tuyau qui change la direction du pipeline. Le coude en acier inoxydable est un coude en acier inoxydable comme matière première principale. Les coudes en acier inoxydable se distinguent généralement des coudes en acier au carbone. Leur principale différence réside dans les différents matériaux, qui présentent diverses caractéristiques.

Classification: Selon l'angle du coude, il existe généralement trois types de coudes en acier inoxydable, y compris un angle de 45 degrés, 90-angle de degré, et angle de 180 degrés. Ces trois sont les spécifications les plus courantes des coudes en acier inoxydable, qui sont plus populaires.

Caractéristiques: La plus grande caractéristique du coude en acier inoxydable est qu'il n'est pas facilement corrodé et rouillé, donc la durée de vie est plus longue. Stainless steel itself is a steel that is resistant to air, steam, and weakly corrosive chemicals. Stainless steel elbows made from it are naturally equipped with weak corrosion resistance. Par conséquent, stainless steel elbows have gradually replaced traditional elbows and are widely used. used.

Corrosion resistance of stainless steel elbow:
The stainless steel elbow has the advantages of smooth inner wall, low resistance to heat medium flow, acid and alkali resistance, long service life, and easy installation. Stainless steel elbows are resistant to corrosion by weak corrosive media such as air, steam, water, and chemically corrosive media such as acids, alkalis, and salts. Also known as stainless acid-resistant steel. In practical applications, steel that is resistant to corrosion by weakly corrosive media is often called a stainless steel stamped elbow, and steel that is resistant to chemical media is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter are generally stainless.
The corrosion resistance of stainless steel elbows depends on the alloying elements contained in the steel. Chromium is the basic element that enables stainless steel elbows to obtain corrosion resistance. When the chromium content in the steel reaches about 1.2%, chromium interacts with the oxygen in the eroding medium to form a thin oxide film on the steel surface (self-passivation) Membrane), can prevent the steel matrix from further erosion. Stainless steel elbows have different production processes and processes. In the processing, they need to be produced and processed according to certain conditions. Elbow fittings of different properties need to pay attention to some matters during processing.
