The Steel Pipe Simplifies The Manufacturing Process And Saves Materials

Steel pipe standard. This steel pipe (fluid pipe) is a hollow section with no welds from start to finish. The steel pipe has a hollow section, and is widely used as a pipeline for transporting fluids to transport oil, natural gas, gas, water and certain solid materials. GB8163 steel pipe is a seamless steel pipe for fluid transportation (GB/T8163-2018), which is a general seamless steel pipe used to transport water, oil, gas and other fluids.

① Generally, the temperature of boiler tubes is below 450 °C, and domestic tubes are mainly made of No. 10 and No. 20 carbon steel hot-rolled tubes or cold-drawn tubes.

② High-pressure boiler tubes are often used in high temperature and high pressure conditions, and the tubes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. The steel pipe is required to have high lasting strength, high oxidation corrosion resistance, and good organizational stability.

GB8163: Standard for steel pipes. This steel pipe (fluid pipe) is a hollow section with no welds from start to finish. The steel pipe has a hollow section, and is widely used as a pipeline for transporting fluids to transport oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, the steel pipe is lighter in weight when the bending and torsional strength is the same. and steel scaffolding used in building construction. Making ring parts with steel pipes can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets, etc., which have been widely used in steel pipe manufacturing. Steel pipe is also an indispensable material for various conventional weapons. Gun barrels, barrels, etc. must be made of steel pipes. Steel pipes can be divided into round pipes and special-shaped pipes according to the shape of the cross-sectional area. Since the area of the circle 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, so most steel pipes are round pipes.
