The main purpose of alloy steel pipe is used in high-pressure high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters. It is made of high-quality carbon steel, alloy structural steel and stainless steel. It is formed by hot rolling (extrusion, expansion) or cold rolling (drawing).

Alloy pipe is a kind of seamless steel pipe. The alloy pipe is divided into structural seamless pipe and high pressure heat resistant alloy pipe. Mainly different from the production standard of alloy tube and its industry, the alloy tube is annealed and quenched to change its mechanical properties. Achieve the required processing conditions. The performance of the seamless steel pipe is higher than that of the general seamless steel pipe. The chemical composition of the alloy pipe contains more Cr, high temperature resistance, low temperature resistance and corrosion resistance. The carbon seamless pipe contains no alloy composition or few alloy components. The reason why the alloy pipe is widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries is because the mechanical properties of the alloy pipe are changed and adjusted.

The alloy pipe is defined by the production material (that is, the material). As the name suggests, it is the pipe made of alloy; and the seamless pipe is defined by the production process (seam seamless), which is different from the seamless pipe. There are seam pipes, including straight seam welded pipes and spiral welded pipes.seamless pipe suppliers

The alloy tube has a hollow section and is used as a conduit for transporting fluids, such as oil, natural gas, gas, water, mechanical processing, and some solid materials. Compared with solid steel such as round steel, alloy steel pipe has light weight when the bending and torsional strength are the same. Alloy steel pipe is an economical section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe and automobile transmission. Shafts, bicycle frames, and steel scaffolding used in construction.

The use of alloy steel pipe to manufacture ring parts can improve the material utilization rate, simplify the manufacturing process, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc., and have been widely used in steel pipes. Alloy steel pipes are also indispensable materials for various conventional weapons, and barrels, barrels, etc. are all made of steel pipes. Alloy steel pipes can be divided into round pipes and shaped pipes according to the shape of the cross-sectional area. Since the area of ​​the circle is the largest under the condition of equal circumference, more fluid can be transported by the circular tube. In addition, the circular section is subjected to a relatively uniform force when subjected to internal or external radial pressure, and therefore, most of the steel pipes are round pipes.

Alloy tubes are large-diameter alloy tubes, thick-walled alloy tubes, high-pressure alloy tubes, alloy flanges, alloy elbows, P91 alloy tubes and seamless tubes, and special fertilizer tubes are also very common.
