A steel pipe machine, or pipe mill, is industrial equipment dedicated to the manufacture of welded steel pipes, which are primarily used for the conveyance of fluids (water, oil, gas) and in structural applications like scaffolding. While sometimes used interchangeably with "tube mill," the machinery for pipe production is often optimized for creating round profiles with an emphasis on pressure-bearing capacity and internal surface quality . Shijiazhuang Faith Machinery Co., Ltd. manufactures these machines to produce pipes that comply with international standards for various industrial uses.
The production workflow in a modern steel pipe machine is a highly automated process . It starts with the uncoiling of the steel strip, followed by leveling and edge preparation . The strip is then progressively formed into a round pipe blank. The welding process is critical; High-Frequency Induction Welding is a common method where the open edges are heated and forged together under pressure to create a continuous, strong seam . Internal and external flash removal is then performed to ensure a smooth weld contour.
After welding, the pipe is guided through a sizing section to calibrate its outer diameter to precise specifications. This is often followed by cooling and straightening . The continuous pipe is cut to length using a flying saw . Finally, the pipes may undergo various finishing processes and inspections, which can include hydrostatic testing to verify pressure resistance, visual checks, and dimensional verification before being packaged for dispatch.
These machines from Shijiazhuang Faith Machinery Co., Ltd. are designed for durability and continuous operation, featuring intelligent PLC control systems for simple operation and monitoring . The resulting pipes are supplied to sectors such as oil and gas, water distribution, industrial fluid transport, and construction, meeting the specific demands for strength and reliability in these applications.
