Tube Mill Machine - MG60: Heavy-Duty ERW Welded Pipe Production Line

Overview

The MG60 tube mill machine by Maxmach is a heavy-duty ERW welded pipe production line engineered for medium-to-large diameter pipes. It produces round pipes from Φ22mm to Φ76mm (wall thickness 0.8–3.5mm) and square pipes from 18×18mm to 50×50mm (wall thickness up to 2.75mm), with adjustable rolling speed of 30–90 m/min. The complete line spans from uncoiler to automatic packing, delivering continuous, high-efficiency pipe production with minimal operator intervention.

Compared to smaller models, the MG60 pipe making machine is purpose-built for heavier wall thicknesses and larger diameters-ideal for structural steel, mechanical tubing, and furniture frames that demand greater load-bearing capacity. Its reinforced forming section and higher-powered drive system ensure stable output even at maximum specifications.

Key Specifications

Components List

The MG60 tube manufacturing equipment is delivered as a turnkey production line. Every component is factory-tested and pre-aligned before shipment, reducing on-site installation time and ensuring start-up reliability.

Production Process

The MG60 welded pipe production line operates in a continuous flow: the uncoiler feeds steel strip into the line, the shearing & butt welding machine joins coil tails and heads for uninterrupted supply, and the squirrel-cage accumulator buffers strip during coil changes. The forming section gradually shapes the flat strip into a round tube blank, which is then HF welded, cooled, and sized to precise dimensions. Finally, the computer cutting saw cuts pipes to length, and the automatic packing machine bundles finished pipes.

Technical Highlights

Double-Side Manual Uncoiler

Supports and rotates heavy steel coils with a manual expansion mechanism. The double-side design allows the operator to load a new coil on one side while the other side feeds the line, minimizing changeover downtime. A braking system prevents coil overspin for safe, controlled strip payout.

Squirrel-Cage Accumulator

Unlike the vertical accumulator used in smaller models, the MG60 employs a squirrel-cage accumulator with 100–300m of strip storage capacity. This design handles thicker, wider strip more effectively and ensures the tube mill machine runs continuously even during coil changes, maximizing production uptime.

Forming, Welding & Sizing System

The reinforced forming section uses larger-diameter rollers and heavier-duty stands to handle thicker strip (up to 3.5mm). The HF welder delivers consistent electromagnetic energy for clean, strong seam welds. After welding, the cooling tank uniformly cools the tube, and the sizing mill precisely calibrates dimensions with multiple sizing passes for tight tolerances.

Computer Cutting Saw & Automatic Packing

The CNC-controlled cutting saw delivers precise, burr-free cuts at programmed lengths. Downstream, the automatic packing machine bundles finished pipes at line speed-a key advantage over the manual run-out table used in smaller models. This eliminates a labor bottleneck and ensures consistent bundle quality for shipping.

Solid State HF Welder

The solid-state high-frequency welder uses advanced electromagnetic induction to heat strip edges to welding temperature, then pressure rollers fuse the edges into a seamless joint. Solid-state technology offers higher efficiency, longer service life, and more stable output compared to vacuum-tube welders.

Why Choose the Maxmach MG60?

Heavy-Duty Capability: Handles pipes up to Φ76mm and 3.5mm wall-built for structural and mechanical applications that smaller machines cannot serve.

Automated End-to-End: From uncoiler to automatic packing, the MG60 minimizes manual handling and labor costs compared to lines with run-out tables.

Squirrel-Cage Accumulator: Superior strip buffering for thicker material ensures zero-downtime coil changes and maximum production continuity.

CNC Precision Cutting: Computer-controlled saw delivers repeatable length accuracy, reducing material waste and rework.

Maxmach Quality: Backed by 50 years of tube mill machine manufacturing expertise with comprehensive after-sales support.

Applications

The MG60 tube mill machine produces pipes for demanding applications: structural steel construction (columns, beams, scaffolding), mechanical tubing (hydraulic cylinders, drive shafts), furniture frames (heavy-duty tables, industrial shelving), handrails & fencing (commercial and infrastructure projects), and automotive components (roll bars, exhaust systems). Its larger diameter and thicker wall capacity open market segments beyond the reach of smaller machines.
