The large-diameter square tube is a long strip of steel with a hollow section and no joints around it. The steel pipe has a hollow cross-section and is used in large quantities as a pipe for conveying fluids, such as pipes for transporting petroleum, natural gas, coal gas, water, and certain solid materials. The use of steel pipes for the manufacture of annular parts can increase the material utilization, simplify the manufacturing process, save material and processing man-hours, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes are widely used for manufacturing. Here's a look at the use of large diameter pipes of large diameter pipe and practical application. The use of large-caliber square tube Large-diameter square pipes are used in large quantities as pipes for transporting fluids, such as pipes for transporting oil, natural gas, gas, water, and certain solid materials. Large-diameter square pipes are also widely used in the manufacture of structural parts and mechanical parts such as oil drill pipes, automobile drive shafts, bicycle racks, and steel scaffolding used in construction. The advantages and disadvantages of steel pipe advantage Compared with solid steel such as round steel, steel pipes have a lighter weight when subjected to the same flexural and torsional strength, and are economical cross-section steels. They are widely used in the manufacture of structural and mechanical parts such as oil drill pipes, automobile transmission shafts, and bicycles. Frames and steel scaffolds used in construction. The use of steel pipes for the manufacture of annular parts can increase the material utilization, simplify the manufacturing process, save material and processing man-hours, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes are widely used for manufacturing. Shortcomings Steel pipe is also an indispensable material for various conventional weapons. The barrels, barrels, etc. must be made of steel pipes. According to the shape of the cross-sectional area, steel tubes can be divided into round tubes and shaped tubes. Since the circle area is the largest under the condition of the same circumference, more fluid can be transported by the circular tube. In addition, when the ring section is subjected to internal or external radial pressure, the force is more uniform. Therefore, most steel pipes are round pipes. However, the circular tube also has certain limitations. For example, under the conditions of plane bending, the circular tube is not as strong as the square and Rectangular Tube, and some agricultural machinery skeletons, steel-wood furniture, etc. are commonly used and rectangular tubes. According to different uses also need to have other cross-sectional shape of the special-shaped steel pipe. Large-diameter square tube practical application 1. Large-diameter square tubes for structures are large-diameter square tubes for general structures and mechanical structures. 2. The large-diameter square tube for fluid transport is a general large-diameter square tube for conveying fluids such as water, oil, and gas. 3. The large-diameter square tube for low and medium pressure boilers is used to manufacture high-quality carbon for various types of low and medium pressure boiler superheated steam pipes, boiling water pipes, superheated steam pipes for boilers, large smoke pipes, small smoke pipes, and arched brick pipes. Structural steel hot-rolled and cold drawn (rolled) large-diameter square tube. 4. Large-diameter square tubes for high pressure boilers are high-quality carbon steel, alloy steel and stainless steel heat-resistant steel large-diameter square tubes for the heating surface of water-tube boilers used to produce high pressure and higher pressures. 5. High-pressure large-diameter square tube for chemical fertilizer equipment is a high-quality carbon structural steel and alloy steel large-diameter square tube suitable for chemical equipment and pipelines with an operating temperature of -40 to 400°C and a working pressure of 10 to 30 Ma. 6. Large-diameter square pipes for oil cracking are furnace pipes, heat exchangers and large-diameter square pipes suitable for petroleum refineries. 7. Steel pipes for geological drilling are steel pipes used by the geological department for core drilling. They can be divided into drill pipes, drill collars, core pipes, casing pipes and sedimentation pipes according to their purposes. Editor's summary: The information on the use of large-diameter square tubes and the practical application of large-diameter square tubes was introduced here. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom.
