Stainless steel elbow is also one of the strongest materials in building metal materials. Because stainless steel elbow has good corrosion resistance, it can make structural parts permanently maintain the integrity of engineering design. Chromium-containing stainless steel elbows also gather machinery Strength and high extensibility in one body, easy to manufacture parts to meet the needs of architects and structural designers.

All metals react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel continues to oxidize, causing the rust to expand and eventually form pores. It can be painted or resistant to oxidation. Metals (eg, zinc, nickel, and chromium) are electroplated to ensure the carbon steel surface, but, as is known, this protection is only a film. If the protective layer is destroyed, the underlying steel begins to rust and resist Corrosive medium such as air, steam, water and other weakly corrosive media and chemically etched media such as acid, alkali, salt, etc. Also known as stainless acid-resistant steel. In practical applications, steel that is resistant to weak corrosive media is often referred to as stainless steel. Steel resistant to chemical media is called acid-resistant steel.

Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally rust-resistant. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is the corrosion resistance of stainless steel. The basic element of sex, when the chromium content in the steel reaches about 1.2%, the action of chromium in the corrosive medium forms a thin oxide film (self-passivation film) on the steel surface, which can prevent the steel matrix from further Corrosion. In addition to chromium, commonly used alloying elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various applications on the microstructure and properties of stainless steel.


Stainless steel elbows do not cause corrosion, pitting, rust or wear. In the piping system, the stainless steel elbow is a pipe that changes the direction of the pipe. According to the angle, there are three most commonly used, 45° and 90°180°. In addition, according to the engineering needs, other abnormal angle elbows such as 60° are included. The materials of the elbow are cast iron, stainless steel, alloy steel, calcinable cast iron, carbon steel, non-ferrous metals and plastics. The way to connect with the pipe is: direct welding (The most common way) flange joint, threaded joint and socket type joint. According to the production process, it can be divided into: welding elbow, stamping elbow, casting elbow, etc. Connection at the bend of the pipe. Other names: 90 degree elbow, right angle bend, love and bend.
Use: Connect two pipes with the same nominal diameter to make the pipe turn 90 degrees.
1. Divided by material into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leaching, ppc, etc.
2. According to the production method, it can be divided into push, press, forge, casting, etc.
3. According to the manufacturing standards, it can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
