Advantages of forming process of stainless steel elbow

　　The main difference between stainless steel elbow and carbon steel elbow is the difference of material. The chemical composition contained in it will keep the elbow surface from rusting and corrosion for a long time.

　　Advantages of forming process of stainless steel elbow:

　　1. The thick wall elbow does not need the pipe blank as the raw material, which can save the cost of pipe making equipment and mold, and can obtain the push elbow with arbitrary large diameter and relatively thin wall thickness. The raw materials of this kind of stainless steel thick wall elbow are relatively special. There is no need to add pipe blank raw materials, which is easy to control during processing.

　　2 the blank for processing stainless steel thick wall elbow is flat plate or developable curved surface, so the blanking is simple, the accuracy is easy to ensure, the assembly and welding is convenient, the raw materials are easy to control during processing, the operation is relatively simple, there are no complicated processes, and the welding and assembly are relatively convenient.

　　Because of these advantages, the manufacturing cycle can be shortened and the production cost can be greatly reduced. Because stainless steel elbow has good comprehensive performance, it is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and light industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding and so on.

　　The chemical composition contained in the stainless steel elbow will keep the elbow surface from rusting and corrosion for a long time.

　　Introduction to stainless steel elbow:

　　1. Inner wall finish: the finish of the inner wall of stainless steel elbow fittings avoids the condensation of impurities. It is the most ideal material in construction.

　　2. High tensile strength: the tensile strength greater than 530n / ㎡ is 2-10 times higher than that of ordinary water pipe materials.

　　3. Good temperature resistance: some pipes begin to precipitate harmful substances at 40 ℃ and produce peculiar smell; The inner wall of some pipes corrodes rapidly under temperature, which shortens the service life of pipe fittings. Stainless steel can work safely for a long time at - 270 ~ 400 ℃ and has stable performance.

　　4. Excellent wear resistance: if the pipe fittings are easily cut by water flow, they will become a killer of human health. Stainless steel fittings can withstand up to 20 m / s fluid environment.

　　5. Unique passivation effect: pH value in water, air, dissolved oxygen, impurities, water treatment agent, etc. can be the causes of pipe corrosion. Stainless steel pipe fittings have a thin and dense oxide film, which can react with oxidant and prevent further oxidation reaction.
