Elbow is a pipe fitting that connects two pipes with the same nominal diameter to make the pipe turn at 90 degree or other angles. Its material is various, among them, alloy elbow is widely used.Alloy elbow materials are various, common are carbon steel, manganese steel, nickel steel and so on. Alloy elbow is widely used. Common bronze alloy elbows are common in common water pipes, but with the improvement of living standards, many water pipes have strong impact.
Therefore, it is often used in high temperature water vapor pipeline and water gas pipeline. In the pipeline with serious wear consumption, such as transmission pipeline.The common bronze alloy elbow is common in the general water pipe, but with the improvement of living standard, many water pipes use stainless steel elbow.
1. The alloy elbow made of manganese steel is usually used in concrete pipeline, mud pipeline and other pipelines with serious wear consumption because of its excellent performance of bearing impact, extrusion and material wear.
2. While the high manganese steel alloy elbow is used in the pipeline with intense fluid flow and strong impact.
3. The alloy elbow made of nickel steel is usually used in the normal temperature pipeline with high concentration of oxidizing acid (nitric acid, sulfuric acid).
4. But it will be severely corroded in the pipeline with reducing acid (hydrochloric acid, dilute sulfuric acid, etc.), unless the concentration of hydrochloric acid is very low.
5. The martensitic alloy elbow has high temperature strength, oxidation resistance and water vapor corrosion resistance under 650 ℃, but its weldability is poor .
6. Therefore, it is often used in high temperature water vapor pipeline and water gas pipeline.
1. According to the curvature radius, alloy elbow can be divided into long radius elbow and short radius alloy elbow.
2. Long radius alloy elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, that is, r = 1.5D.
3. Short radius alloy elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, r = 1.0d. (D is the diameter of alloy elbow, R is the radius of curvature).
4. The manufacturing standards of alloy elbow are GB, anis, JIS, BS, DIN, etc.
5. According to the pressure rating, there are about 17 kinds of alloy elbows, which are the same as the standards of pipes.
6. It including: sch5s, sch10s, sch10, sch20, sch30, sch40s, STD, sch40, sch60, sch80s, XS; sch80, schh100, sch120, sch140, sch160, XXS; and STD and XS are commonly used.

1, Because of its wear-resistant, corrosion-resistant and heat-resistant properties, alloy elbow can be widely used in electric power, metallurgy, mining, coal, chemical industry and other industries as abrasive materials and corrosive media.
2, Such as sand, stone, coal powder, ash, aluminum liquid, etc., and it is an ideal wear-resistant pipeline.
1. The transportation of coal powder, cinder, mud, lime gypsum slurry and so on in metallurgy and electric power industry needs a large number of metal pipelines every year.
2. The ceramic composite pipe has the advantages of high wear resistance, long service life, convenient installation and remarkable economic benefits.
1. Mine: the pipeline of mine filling, concentrate powder and tailings transportation is seriously worn.
2. The service life of the pipeline used in the past, such as Panzhihua and Daye Mine, is less than one year, which can be increased by 5 times.
3. Coal: wet transportation is widely used in coal preparation and long-distance pipeline transportation, which requires that the conveying pipe is wear-resistant and corrosion-resistant.
4. The pipe can be used as a long-term conveying pipe with considerable economic benefits.
