Rectangular Pipe Or indispensable information on various conventional weapons

square Torque tube With hollow section, a large number of pipes are used to escort fluids, such as pipes for petroleum, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, square tube is lighter when its bending and torsional strength is the same. It is a kind of steel with economic section and is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction Square tube manufacturing Annular parts can improve the application rate of data, simplify the manufacturing process, and save data and processing time, such as rolling bearing rings, jack sleeves, etc., which are now commonly manufactured with square tubes. Square tubes are indispensable materials for all kinds of conventional weapons. Gun barrels and gun barrels should be made with square tubes. Square tubes can be divided into round tubes and special-shaped tubes according to the shape of cross sectional area. Since the circle area is large under the condition of equal perimeter, more fluid can be transported by using circular tubes. In addition, when the ring section receives internal or external radial pressure, the force is relatively average, so most square tubes are round tubes.  

However, circular pipes also have corresponding limitations. For example, under the condition of plane bending, circular pipes are not as strong as square and rectangular pipes in bending strength. Square and rectangular pipes are commonly used for some agricultural machinery frameworks, steel and wood furniture, etc. According to different uses, special-shaped square tubes with other sectional shapes are also required.
