Contact and difference with seamless tubes

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.


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.
