Carbon steel elbow is widely distributed in thermal power, steel, smelting, cement, machinery, coal, mining, chemical industry, port and other industries with serious wear and tear.The carbon steel elbow fully displays the good performance superiority, can guarantee the important use performance and the operation contribution.
Wear of carbon steel elbow has always been a factor affecting civilized production. With the continuous development of science and technology, materials have also been constantly innovated, such as cast stone, cast steel, alloy, centrifugal casting composite ceramics and other materials.Among them, the pipeline lining alumina ceramics with its high wear resistance, high hardness, oxidation resistance, corrosion resistance and high resistance to high and low temperature strength performance.
Corrosion resistance of carbon steel elbows depends on the alloying elements contained in the steel
Carbon steel elbow is resistant to air, steam, water and other weak erosion medium and acid, alkali, salt and other chemical corrosive medium erosion of steel.Also known as stainless acid - resistant steel.
In practical application, the steel resistant to weak erosion medium is often called stainless steel stamping elbow, and the steel resistant to chemical medium erosion is called acid resistant steel.Because of their differences in chemical composition, the former is not necessarily resistant to chemical medium erosion, while the latter is generally rustproof.
Chromium-free stainless steel stamping elbows are also a combination of mechanical strength and high elongation, easy parts processing and manufacturing, can meet the needs of architects and structural design staff.
Corrosion resistance of carbon steel elbows depends on the alloying elements contained in the steel.Chromium is the basic element to make carbon steel elbow corrosion resistance, when the amount of chromium in steel reaches about 1.2%, chromium and the oxygen in the erosion medium, forming a very thin oxide film on the steel surface, can prevent further erosion of the steel matrix.Stainless steel stamping elbows do not produce erosion, pitting, corrosion or wear.
Stainless steel is still one of the strongest materials in the building metal materials.Because stainless steel has good corrosion resistance, it can make the structural parts to maintain the integrity of the engineering design.Stainless steel is also one of the strength materials in the construction metal materials.Because stainless steel has good corrosion resistance, it can make the structure of the components to maintain the integrity of the engineering design.
Chromium-containing stainless steel is also a combination of mechanical strength and high extensibility, 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.
1. Carbon steel elbow is suitable for pipeline series of petroleum, natural gas, chemical industry, hydropower, construction and boiler industries.
2. Due to the above two reasons, the manufacturing cycle can be shortened and the production cost can be greatly reduced.Since no special equipment is required, it is especially suitable for large carbon steel elbow machining on site.
3. The blank is flat or developable surface, so the blanking is simple, the precision is easy to ensure, and the assembly and welding are convenient.
4. do not need tube billet as raw material, can save the cost of tube making equipment and mold, and can get any large diameter and wall thickness of relatively thin carbon steel elbow.
Carbon steel elbow is a metal pipe fitting used to change the direction of the pipe on carbon steel pipe.The connection way has the thread buckle and the welding.Points according to the Angle 45 ° and 90 ° 180 ° three kinds of commonly used, according to the requirements of the project also includes 60 °, and other abnormal Angle bend.The material of elbow has cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metal and plastic to wait.
Connection with the pipe: direct welding (common way) flange connection, hot melt connection, electric melt connection, thread connection and socket connection.According to the production process can be divided into: welding elbow, stamping elbow, push system elbow, casting elbow.Other names: 90 degree bend, right Angle bend, love and bend, etc
