Carbon steel seamless tube
Steel pipe with hollow section is widely used for conveying fluid, such as conveying oil, natural gas, gas, water and some solid materials. Steel tube and round steel and other solid steel, in the same flexural and torsional strength at the same time, light weight, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and construction of steel scaffolding.
Circular parts made of steel tubes can improve material utilization, simplify manufacturing process and save material and processing time. For example, rolling bearing rings, jack sleeves, etc., steel tubes have been widely used in manufacturing.
Steel pipe is an indispensable material for all kinds of conventional weapons. Steel tubes can be divided into round tubes and special-shaped tubes according to the shape of cross-sectional area. Since the circular surface product is the largest under the condition of equal perimeters, more fluid can be transported with circular tubes. In addition, when the annular section bears internal or external radial pressure, the force is more uniform, so most steel tubes are round tubes.
