Introduction to stainless steel elbow

Stainless steel elbows and other elbows are mainly different in material, let's introduce it below. Stainless steel elbows and other elbows are mainly different in material, let's introduce it below. The main difference between stainless steel elbows and carbon steel elbows is the difference in material. The chemical composition contained in the elbow will keep the surface of the elbow from rust and corrosion for a long time. In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three commonly used elbows of 45 and 90180, and other abnormal angle elbows such as 60 are also included according to engineering needs. The materials of the elbow include cast iron, stainless steel, alloy steel, forgeable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect with the pipe are: direct welding (commonly used) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, hot pressing elbow, push elbow, casting elbow, forging elbow, clip elbow, etc. Other names: 90 elbow, right angle bend, love bend, white steel elbow, etc. According to the standard production, it can be converted into: 1. According to the manufacturing standard, it can be divided into national standard, ship standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc. 2. According to the production method, it can be divided into pushing, pressing, forging, casting, etc. The 90 stainless steel elbow is mainly used for connecting pipe fittings in pipeline installation, and is used for connecting pipe bends. Connect two pipes with the same or different nominal diameters to make 90 turns. Stainless steel is usually made of carbon steel with a high proportion of Cr, Ni and other alloys, and the content ratio can reach more than 20%. Common steel grades are: 304, 304L, 321, 316, 316L, 1Cr18Ni9Ti, 0cr18ni9. The first number of steel numbers represented by numbers is Japan and the United States steel number representation method, the latter (1Cr18Ni9Ti) is the domestic steel number representation method. Stainless steel characteristics: strength and toughness indicators are the best among various steels. Its outstanding advantage is corrosion resistance. Stainless steel must be used in highly corrosive occasions such as chemical papermaking. Of course, the cost is also higher!
