  • Detail

Large diameter square tube is a kind of long steel with hollow section and no joints around. Steel pipes have hollow sections and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and some solid materials. Using steel pipes to make annular parts can improve the utilization rate of materials, simplify the manufacturing process, and save materials and processing hours, such as rolling bearing rings, Jack sleeves, etc. at present, steel pipes have been widely used to manufacture. Let's take a look at the use of large-diameter square tubes and the practical application of large-diameter square tubes

Let's take a look at the use of large-diameter square tubes and the practical application of large-diameter square tubes

use of large-diameter square tubes

large diameter square tubes are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and some solid materials. Large diameter square tubes are also widely used to manufacture structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolds used in construction

advantages and disadvantages of steel pipe

advantages

compared with solid steel such as round steel, steel pipe has the same bending and torsional strength, and its weight is lighter. It is a kind of economic section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolds used in construction. Using steel pipes to make annular parts can improve the utilization rate of materials, simplify the manufacturing process, and save materials and processing hours, such as rolling bearing rings, Jack sleeves, etc. at present, steel pipes have been widely used to manufacture

disadvantages

steel pipe is also an indispensable material for all kinds of conventional weapons. Gun barrel, barrel, etc. should be made of steel pipe. Steel pipes can be divided into round pipes and special-shaped pipes according to the shape of cross-sectional area. Because the circular area is the largest under the condition of equal perimeter, more fluid can be transported with a circular tube. In addition, when the ring section is subjected to internal or external radial pressure, the force is relatively uniform. Therefore, the vast majority of steel pipes are round pipes. However, circular pipes also have certain limitations. For example, under the condition of plane bending, the bending strength of circular pipes is not as strong as that of square and rectangular pipes. Square and rectangular pipes are commonly used in the framework of some agricultural machines and tools, steel and wood furniture, etc. Special shaped steel pipes with other cross-section shapes are also required according to different uses
