The Role of the Furiwo 76 Used High-Frequency Welding Pipe Mill in Production

The used pipe mill, specifically the Furiwo 76 model, represents a complete, refurbished production line designed for the efficient manufacturing of welded steel pipes. Its role in the industrial manufacturing process is central, transforming raw coiled strip steel into finished round, square, and rectangular tubes of precise dimensions. As a used pipe mill, it offers a cost-effective solution for entering or expanding within the metal pipe production sector, providing robust capability without the capital expenditure of new machinery.

In the production workflow, this used pipe mill acts as the core converting unit. The process begins with the manual double cone uncoiler, which feeds the steel coil into the system. The subsequent horizontal loop serves as a critical buffer, ensuring a continuous and steady supply of strip steel to the main forming section, thereby preventing interruptions and maintaining consistent production speed—a key factor in achieving the rated output of up to 100 meters per minute.

The primary transformation occurs within the forming and sizing machine. This section, with its configuration of 7 horizontal and 8 vertical stands for forming followed by 5 horizontal and 5 vertical stands for sizing, progressively shapes the flat strip into a cylindrical form with the open seam precisely aligned. The use of Φ60 rollers (molds) allows for the flexibility to produce the advertised range of pipe diameters from Φ20mm to Φ76mm. The used pipe mill's capability to handle material thicknesses from 0.8mm to 4.0mm for round pipes (and slightly less for square and rectangular profiles) demonstrates its suitability for manufacturing both lightweight and medium-duty structural pipes.

The heart of the welding process is the 300kW high-frequency (HF) welder. At this stage, the open edges of the shaped strip are brought together under pressure and heated by high-frequency current, creating a strong, continuous longitudinal seam. The quality and speed of this solid-state welding process are fundamental to the used pipe mill's productivity and the integrity of the final product.

Following welding, the now-closed pipe passes through the sizing stands for final calibration to exact dimensional tolerances and roundness/squareness. The cutting saw, driven by a servo system, then accurately cuts the continuous pipe into predetermined lengths. The 10-meter-long run-out table facilitates the handling and cooling of the finished pipes before they are collected for further processing, inspection, or shipment.

The role of this used pipe mill extends beyond mere shaping and joining. Its defined processing capacity makes it a versatile asset in manufacturing pipes for various applications, including furniture frames, automotive parts, construction scaffolding, and lightweight structural components. The specification of a right-hand feed direction standardizes the operator's interaction with the machine for safety and workflow efficiency.

Crucially, its status as a refurbished used pipe mill—with maintained mechanical components and tested, operational electrical systems—means it delivers immediate production readiness at a significantly lower entry cost (EXW 550,000 RMB) compared to a new equivalent. It enables small to medium enterprises to establish or enhance their pipe production capability reliably. Therefore, the Furiwo 76 used pipe mill plays the indispensable role of a fully-integrated, value-driven manufacturing system that efficiently converts raw steel coil into a wide array of commercial and industrial tubular products.
