The main difference between stainless steel elbow and carbon steel elbow is the material.
The main difference between stainless steel elbow and carbon steel elbow is the material. The chemical composition of stainless steel elbow will keep its surface from rust and corrosion for a long time.
In a pipe system, a bend is a pipe fitting that changes the direction of the pipe. Points according to the Angle 45 ° and 90 ° 180 ° three most commonly used, according to the requirements of the project also includes 60 °, and other abnormal Angle bend.
The bending materials include cast iron, stainless steel, alloy steel, calcinable cast iron, carbon steel, non-ferrous metal and plastic, etc. The pipe is connected by direct welding (most commonly used) flange connection, hot-melt connection, electric welding 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, clamping elbow, etc. Other names: the 90 ° elbow, elbow bend, love and curved, white steel elbow, etc.
Produced According to Standard:
1. The manufacturing standards can be divided into national standards, ship standards, electrical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.
2. The production method can be divided into pushing, pressing, forging, casting, etc.
90 ° bend is mainly used for stainless steel pipe installation, a connecting pipe used for connection pipe bend. Connect two of the same or different nominal diameter tube, and make the line turn 90 °.
It is usually made by adding high proportion Cr, Ni and other alloys on the basis of carbon steel, and the content ratio can reach more than 20%. Common types of steel are: 304, 304 L, 321, 316, 316 L, 1Cr18Ni9Ti, 0cr18ni9.
Features: stainless steel strength, toughness index is good in all kinds of steel, the most prominent advantage is corrosion resistant, in chemical industry, papermaking and other corrosive strong occasion must be used stainless steel, of course, the cost is higher!
