Management Platforms

Uncoiling & Feeding

Hydraulic decoilers and end shear welders ensure a continuous, tension-free strip supply for the mill.

Precision Forming

Multiple forming sections gradually shape the strip into a precise round or square profile.

HF Welding Control

Solid-state HF welders with magnetic rods focus heat precisely at the edges for seamless joining.

Burr Removal System

Integrated inner and outer weld bead removal tools ensure a smooth surface finish throughout the pipe.

Cooling & Sizing

Water cooling and sizing sections lock in the dimensions and eliminate internal stresses.

Automatic Cutting

Flying cold or hot saws provide precise length cutting without stopping the production line.

Frequently Asked Questions

Q: What is the primary difference between ERW and other welding methods in tube mills?

Electric Resistance Welding (ERW) uses high-frequency current to heat the edges of the steel strip, creating a solid-state bond without filler metal, resulting in higher production speeds and cleaner seams compared to traditional methods.

Q: Can this 114mm ERW mill produce both round and square tubes?

Yes, the equipment is designed for both round-to-round and round-to-square forming processes, provided the appropriate sizing and forming rollers are installed.

Q: How does the automatic flying cut-off system work?

The flying saw synchronizes its movement with the speed of the pipe moving through the line, allowing it to cut the pipe to the exact required length without stopping the mill, which maximizes throughput.

Q: What materials are best suited for this tube mill?

This mill is primarily engineered for Carbon Steel coils, specifically tailored for applications in the general equipment and metal products manufacturing industry.

Q: What certifications does the equipment comply with?

Our machinery is manufactured and exported in compliance with CE and ISO standards, ensuring safety and quality requirements for various destination customs.

Q: How is the internal weld bead handled?

The mill features an optional automatic lifting inner weld bead scraper that removes the internal burr immediately after welding, ensuring the interior of the pipe is clean and smooth.
