Specifications and Maintenance of Pipe Coning Machines

Pipe coning machines are essential tools in metal fabrication, used to create tapered ends on pipes for welding, flaring, or specialized connections. Understanding their technical specifications ensures compatibility with project requirements, while consistent maintenance extends equipment life and ensures precision and safety during operation.

Key Technical Specifications

Branch Diameter Capacity

Pipe coning machines are designed to handle a wide range of pipe diameters, making them versatile across various industrial applications. Most models support branch diameters ranging from 60mm (2 inches) up to 350mm (14 inches), allowing for both small-scale plumbing work and large-diameter structural piping.

Choosing the right machine depends on your typical pipe size usage. Machines with larger diameter capabilities often feature reinforced frames and higher torque systems to manage increased material resistance during the coning process.

Pipe Cone Length

The maximum cone length a machine can produce varies significantly by model and design. Some compact units offer cone lengths up to 300mm, while industrial-grade machines can form tapers extending to 500mm or more.

This specification is crucial for applications requiring long, gradual tapers such as exhaust systems, HVAC ducting, or custom weld preps. Always verify that your machine’s cone length capability aligns with your fabrication needs to avoid limitations in design flexibility.

Fillet Radius (Able Radius)

The minimum fillet radius, or "able radius," determines how tight a curve the machine can produce at the base of the cone. Advanced models can achieve radii as small as 5mm, enabling smooth transitions ideal for high-stress joints and pressure-rated systems.

A smaller radius improves structural integrity and aesthetics but requires more precise tooling and higher machine rigidity. For general applications, a radius between 8–15mm may be sufficient, depending on material thickness and intended use.

Material Thickness Range

Pipe coning machines are engineered to work with a variety of metals and thicknesses. Commonly supported materials include stainless steel, carbon steel, aluminum, and copper alloys, with wall thicknesses typically ranging from 0.5mm to 3mm.

Thicker materials require greater force and slower feed rates, so machines designed for heavy-gauge metal often come with higher-powered drives and robust tooling. Always confirm compatibility with your most frequently used materials to ensure clean, accurate coning without cracking or deformation.
