Eddy Current Machine for ERW Tube Mill

Itu Eddy Current Testing Machine is an advanced non-destructive testing (NDT) equipment designed for online inspection of welded steel pipes and tubes. It is widely used in ERW tube mills to detect weld seam defects and surface flaws without damaging the pipe.

By using electromagnetic induction technology, this machine ensures stable, high-speed, and reliable quality inspection during continuous pipe production.

Main Applications

The Eddy Current Testing Machine is mainly used for:

• 🔹Weld seam inspection of ERW steel pipes

• 🔹Detection of surface and near-surface defects

• 🔹Online quality control during high-speed tube production

Typical defects detected include:

• 🔹Cracks

• 🔹Pinholes

• 🔹Incomplete welding

• 🔹Surface scratches and laps

It is suitable for carbon steel pipes, structural tubes, and precision ERW pipes.

Position in ERW Tube Mill

In an ERW Tube Mill, the eddy current testing machine is installed:

• After HF welding

• After cooling section

• Before or after the sizing machine

This position allows real-time monitoring of weld quality and helps prevent defective pipes from entering the finishing process.

Prinsip Kerja

1. 📍The probe generates a high-frequency alternating magnetic field

2. 📍Eddy currents are induced on the pipe surface

3. 📍Any defect causes a change in the eddy current signal

4. 📍The system analyzes the signal and triggers alarms or markings

This method is non-contact, fast, and highly sensitive, making it ideal for continuous online inspection.

Key Features

• Online inspection for ERW tube mills

• High sensitivity for weld seam detection

• Stable digital signal processing

• Non-contact testing, no damage to pipes

• Suitable for round, square, and rectangular tubes

• Optional marking and alarm system

• Easy operation and low maintenance

• 

Typical Technical Parameters

(Parameters can be customized according to pipe size and inspection standard)

Eddy Current Testing Machine – FAQ🔍

Q1: What is an eddy current testing machine used for?

A: It is used for non-destructive testing of metal pipes to detect weld seam and surface defects during production, especially in ERW tube mills.

Q2: Can this machine inspect weld seams online?

A: Yes. The eddy current testing machine is designed for online inspection and can continuously monitor weld seam quality during high-speed pipe production.

Q3: Where is it installed in an ERW tube mill?

A: It is typically installed after HF welding and cooling, before or after the sizing section, to ensure weld quality before further processing.

Q4: What types of defects can be detected?

A: Common detectable defects include cracks, pinholes, incomplete welding, and surface flaws near the weld seam.

Q5: Is the testing process harmful to the pipe?

A: No. Eddy current testing is a non-contact and non-destructive inspection method and does not damage the pipe surface.

Q6: What pipe sizes can be inspected?

A: The machine supports a wide range of pipe diameters and wall thicknesses. Specifications can be customized according to production requirements.

Q7: Can it work with other ERW tube mill equipment?

A: Yes. It can be integrated with HF welders, sizing machines, flying saws, and marking systems to form a complete quality control line.
