Industrial High-Frequency (HF) Pipe & Tube Mill
A continuous HF tube mill converts steel strip coils into welded round, square, rectangular, and other tube profiles through forming, high-frequency welding, sizing, and cutting. The mill configuration is determined by the target tube dimensions, wall thickness, steel grade, coil specifications, production requirements, and finished-product standards.

Product Overview
Continuous Coil-to-Tube Production
The line processes steel strip through continuous forming, HF welding, sizing, and cut-to-length operations for efficient tube production.
Configured to Product Requirements
Forming stands, welding equipment, sizing sections, drives, and auxiliary systems are selected according to the required tube range and production conditions.
Multiple Tube Profiles
Depending on the forming and sizing configuration, one production line can be configured for round tubes, square and rectangular tubes, SHS/RHS, and selected mechanical profiles.
Production Flow & Main Equipmentn
Continuous Production Flow
Steel Coil → Uncoiler → Strip End Preparation → Butt Welder → Accumulator → Forming → HF Welding → Weld Bead Removal → Sizing → Cutting → Run-Out & Bundling
Coil Handling & Strip Preparation
Uncoiler, coil car, strip guide, end preparation equipment, and butt welder provide controlled strip feeding and continuous coil joining.
Forming & HF Welding
Breakdown, forming, and fin-pass stands progressively shape the strip before the HF welding section joins the strip edges without filler metal.
Sizing & Cutting
Sizing stands calibrate the formed tube to the specified final dimensions and profile geometry. The cut-off system produces specified finished lengths for downstream handling.
Applications
Structural & Construction
For structural hollow sections, scaffolding tubes, framing components, greenhouse structures, and other fabricated steel applications where the finished product meets the applicable specification.
Automotive & Machinery
For mechanical tubes, equipment frames, fabricated components, and other applications requiring specified tube dimensions and material grades.
Furniture & General Fabrication
For furniture frames, racks, shelving, guardrails, and general fabricated structures using round, square, or rectangular tubes.
Fluid-Service Applications
For specified industrial fluid-service applications where material, dimensional, weld quality, and testing requirements are defined by the applicable product standard.
Manufacturing & Quality Control
Mechanical Assembly
Forming stands, sizing stands, welding equipment, drives, and auxiliary systems are assembled and aligned according to the approved mill configuration.
Electrical & Control Integration
PLC, HMI, drives, sensors, safety interlocks, and line synchronization functions are integrated and checked before commissioning.
Pre-Delivery Inspection
Mechanical movement, drive operation, control functions, welding-system interfaces, and safety functions are checked according to the agreed inspection and commissioning scope.
Inspection & Testing Options
Weld Inspection
Optional eddy current testing and other weld inspection systems can be integrated according to product requirements.
Dimensional Monitoring
Dimensional inspection can be included to monitor specified tube dimensions and profile geometry.
Process Monitoring
Forming, welding, sizing, and line-control parameters can be monitored through the mill control system according to the selected configuration.
FAQ
Q: How is an HF tube mill selected?
A: Selection is based on tube size, wall thickness, steel grade, coil specifications, target production, product profile, and applicable finished-product requirements.
Q: Can one mill produce round, square, and rectangular tubes?
A: A suitably configured mill can produce multiple profiles. The available product range depends on the forming, sizing, and tooling configuration.
Q: What determines the production speed?
A: Line speed depends on tube dimensions, wall thickness, material, HF welding requirements, forming configuration, and cut-off conditions. The applicable speed should be confirmed for the target product range.
Q: Can online weld inspection be integrated?
A: Yes. Eddy current testing and other inspection systems can be integrated when required by the product specification or quality-control plan.
Q: Can the mill be customized for different steel grades?
A: Yes. Material grade, strip dimensions, tube range, and welding requirements are considered when configuring the forming and welding sections.
Q: What information is required for an HF tube mill quotation?
A: Please provide the target tube profile, dimensions, wall thickness, steel grade, coil specifications, required production output or line speed, finished tube length, applicable standards, and required inspection systems.
