The difference between stainless steel elbow and carbon steel elbow is mainly due to the different material. Its chemical composition will keep the elbow surface for a long time without rust and will not be corroded.

In the pipeline system, the elbow is the tube 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 bends, such as 60 degrees, are also included according to the needs of the project.

The bends are made of cast iron, stainless steel, alloy steel, calcinable cast iron, carbon steel, nonferrous metal and plastic. The ways of connecting with the pipe include direct welding (the most commonly used) flange connection, hot-melt connection, electrofusion connection, threaded connection and socket connection. According to the production process, it can be divided into welding elbow, stamping elbow, hot press elbow, pushing elbow, casting elbow, forged elbow, clip elbow, etc. Other names: 90 degrees bend, right angle bend, love bend, white steel elbow and so on.

Long radius elbow of 90 degree stainless steel

1. makes the standard can be divided into standard, standard, standard, ship electric water, American Standard, German standard, Japanese standard, Russian standard, etc..

2. it can be divided into pushing, pressing, forging, casting and so on.

The 90 degree stainless steel elbow is mainly used for the pipe fittings in the pipeline installation, which is used for the connection of the pipe bend. Connect two pipes with the same or different diameters to make the pipe turn 90 degrees.

Stainless steel

On the basis of carbon steel, a high proportion of Cr, Ni and other alloys are added, with a content ratio of more than 20%. Common steel: 304304L, 321316316L, 1Cr18Ni9Ti, 0Cr18Ni9, before several numbers indicate the steel of Japan, the U. S.Steel representation, the last one (1Cr18Ni9Ti) representation for domestic steel.

Stainless steel characteristics: strength and toughness index is the best in all kinds of steel, the most outstanding advantage is corrosion resistance. In chemical and papermaking and other corrosive occasions, it is necessary to use stainless steel, of course, the cost is also high.
