Stainless steel elbows differ from carbon steel elbows mainly in different materials, the chemical composition of which will keep the surface of the elbow will not rust for a long time, will not be corroded.
In the pipeline system, elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, 45 degrees and 90 degrees 180 degrees are the most commonly used, and other abnormal angle elbows such as 60 degrees are included according to the engineering requirements.
Elbows are made of cast iron, stainless steel, alloy steel, calcinable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect with pipes are: direct welding (the most commonly used way) flange connection, hot melt connection, electric melt connection, threaded connection and socket connection. According to the production process, it can be divided into welding elbow, stamping elbow, hot pressing elbow, pushing elbow, casting elbow, forging elbow, clamp elbow and so on. Other names: 90 degree elbow, right angle elbow, love and bend, white steel elbow, etc.

Making according to standards can be transformed into:
1. Manufacturing standards can be divided into national standard, ship standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.
2. It can be divided into pushing, pressing, forging, casting and so on.
The 90 degree stainless steel elbow is mainly used as a connecting fittings in pipeline installation, which is used for the connection of pipeline bends. Connect two pipes with the same or different nominal diameter to make a 90 degree turn.
Usually it is made by adding a high proportion of Cr, Ni and other alloys on the basis of carbon steel, and the content ratio can reach more than 20%. Common steel grades are 304, 304L, 321, 316, 316L, 1Cr18Ni9Ti, 0cr18ni9. The first few steel grades expressed by numbers are Japanese, the last one (1Cr18Ni9Ti) is domestic steel grades.
Stainless steel characteristics: strength, toughness index is the best of all kinds of steel, its most prominent advantage is corrosion resistance, in chemical papermaking and other corrosive occasions must use stainless steel, of course, the cost is higher!
