This invention relates to a pipe forming method, including the following four steps: material preparing and fastening, operation starting, preheat processing, and tube forming. Through these four steps, strip-shaped fiber yarn bundle can be expanded to form a filament-shaped fiber yarn, which is then coated evenly with powder to form a semi-finished product with higher hardness after preheat processing. Finally, pipes are formed by winding the semi-finished product.
