Alloy steel tube
| Item | Alloy steel tube/ pipe |
| Introduction | It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel, and is made by hot rolling (extrusion, expansion) or cold rolling (drawing). Alloy pipes have a hollow section and are used in large quantities as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, coal gas, water and certain solid materials. Compared with solid steel such as round steel, alloy steel pipe is lighter when the bending and torsion strength is the same. Alloy steel pipe is a kind of economical cross-section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes and automobile transmission. Axes, bicycle frames and steel scaffolding used in building construction, etc. The use of alloy steel pipes to manufacture ring-shaped parts can improve material utilization, simplify manufacturing procedures, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc., which have been widely used for manufacturing steel pipes. Alloy steel pipe is also an indispensable material for various conventional weapons. Gun barrels and barrels are all made of steel pipes. Alloy steel pipes can be divided into round pipes and special-shaped pipes according to different cross-sectional area shapes. Since the circle area is the largest under the condition of the same circumference, more fluid can be transported with a circular tube. In addition, when the ring section bears internal or external radial pressure, the force is relatively uniform. Therefore, most steel pipes are round pipes. |
