20# fluid steel pipe is a hollow cross-section steel pipe without welds from beginning to end. It is widely used as a pipeline for conveying fluids, and pipelines for conveying oil, natural gas, coal gas, water and some solid materials.
20# steel pipe can be divided into round pipe and special-shaped pipe according to the shape of the cross-sectional area. Since the area of the circle is the largest when the circumference is equal, more fluid can be conveyed by using a round pipe. In addition, the circular cross-section is subjected to more uniform force when subjected to internal or external radial pressure. Therefore, most steel pipes are round pipes.
