Carbon Steel Tube Extrusion Machine With Add ECT Testing Equipment

Product Overview

The Carbon Steel Tube Extrusion Machine with Add ECT Testing Equipment is designed for producing 1 inch carbon steel tubes, cold rolled steel tubes, and galvanized steel tubes with stable forming, high-frequency welding, sizing, cutting, and optional online non-destructive testing.

For this product page, “tube extrusion machine” refers to a continuous steel tube forming and welding production line, not hot metal extrusion. The standard ZY20 tube making machine is suitable for round tube outer diameters from 10 mm to 25.4 mm, wall thickness from 0.3 mm to 1.5 mm, and welding speed up to 120 m/min.

This line is suitable for manufacturers who need small-diameter carbon steel tubes with higher production efficiency, better weld consistency, and optional ECT testing for quality control before delivery.

The main production flow is:

Uncoiler → Shear & Welding Machine → Accumulator Cage → Forming Machine → HF Welding → Sizing Machine → Flying Cold Saw → Run Out Table → Optional ECT Testing Equipment

Cause

Many buyers do not only need a tube making machine. They need a complete production solution that can reduce tube defects, control weld quality, and keep stable output during continuous production.

For 1 inch carbon steel tube production, the common problems are unstable strip feeding, poor forming accuracy, weld seam defects, inaccurate sizing, and inconsistent cutting length. If these problems are not controlled, the final tube may fail in furniture, construction, electrical conduit, automotive parts, or general industrial applications.

Another important issue is inspection. Standard tube production lines can produce tubes quickly, but some customers also need online testing equipment to detect possible defects such as cracks, pits, inclusions, voids, or sudden dimensional changes.

That is why ECT testing equipment can be added after the welding and sizing process. It helps manufacturers improve inspection efficiency and reduce the risk of unqualified tubes entering the market.

Solution

The ZY20 carbon steel tube production line solves these problems through continuous forming, high-frequency welding, precision sizing, cold saw cutting, and optional online ECT testing.

The forming section gradually shapes cold rolled steel or galvanized steel strip into round tube. The HF welding section joins the strip edges at high speed, while the sizing machine controls the final outer diameter and roundness.

The accumulator cage allows continuous production when coil change or strip welding is required. This reduces downtime and improves production efficiency.

The optional ECT testing equipment can be added according to the pipe standard and customer quality requirements. It is especially useful for buyers who need higher inspection reliability for export orders or industrial tube applications.

Zhongyue Metallurgy Equipment Technology has exported steel pipe making machines to more than 70 countries since 2006, covering Asia, North America, South America, Europe, the Middle East, Southeast Asia, and Africa. The company also improves machine design through real tube production experience, not only through equipment assembly.

Application

This carbon steel tube extrusion machine is suitable for manufacturers producing small-diameter round tubes with stable wall thickness and high line speed.

Typical application scenarios include furniture tubes, chair tubes, light structural tubes, small industrial tubes, electrical conduit tubes, decorative tubes, and general carbon steel pipe production.

For customers producing export tubes or tubes used in stricter industrial applications, optional ECT testing equipment can be added to improve online inspection capability.

For tube factories that need both production speed and quality control, the ZY20 model is a practical choice because it supports 10 mm to 25.4 mm OD production and reaches up to 120 m/min welding speed under suitable material and operating conditions.

How It Works

The production starts from the uncoiler, where steel strip is released into the line. The shear and welding machine connects strip ends, helping the line reduce stoppage during coil change.

The accumulator cage stores strip material and keeps the forming section running continuously. This is important for stable production speed and better output efficiency.

The forming machine gradually bends the steel strip into a round tube shape. Then the HF welding unit heats and welds the strip edges to form a continuous tube.

After welding, the sizing machine corrects the tube diameter and shape. The flying cold saw cuts the tube to the required length without stopping the production line.

If ECT testing equipment is added, the tube can pass through online eddy current inspection after forming and sizing. This helps detect certain surface or near-surface defects in steel tubular products and supports better quality control before packing or further processing.

How To Choose

Choose ZY20 if your main product is 1 inch carbon steel tube or small-diameter round tube from 10 mm to 25.4 mm.

Choose a larger model such as ZY32 or ZY45 if your future production plan includes larger tube diameters or thicker wall tubes. Choosing only by current size may limit your later market expansion.

Choose optional ECT testing equipment if your customers require higher inspection standards, export quality control, or non-destructive testing records.

Choose hydro testing equipment if the tube will be used for pressure-related applications. Choose end facing equipment if the final tube requires better end surface quality for assembly or downstream processing.

Before ordering, buyers should confirm raw material type, strip width, wall thickness range, tube standard, required length, factory layout, power supply, inspection requirement, and target daily output.

FAQ

1. What tube size can the ZY20 carbon steel tube extrusion machine produce?

The standard ZY20 tube making machine can produce round tubes with an outer diameter from 10 mm to 25.4 mm and wall thickness from 0.3 mm to 1.5 mm. It is suitable for 1 inch carbon steel tube production.

2. Why should ECT testing equipment be added to the tube production line?

ECT testing equipment helps inspect steel tubes online and detect possible defects such as cracks, pits, voids, inclusions, or sudden dimensional changes. It is useful when buyers need higher quality control for export or industrial tube applications.

3. Can the production line process galvanized steel strip?

Yes. The line can process cold rolled steel, galvanized steel, and carbon steel strip, as long as the material size and mechanical properties match the machine design.

4. Is the production flow fixed?

No. The standard flow includes uncoiler, shear & welding, accumulator, forming, HF welding, sizing, cold saw, and run out table. According to pipe standards and buyer requirements, hydro testing, end facing, ECT testing, marking, or packing equipment can be added.

5. How do I know whether ZY20 is enough for my factory?

ZY20 is suitable if your target tube OD is mainly 10 mm to 25.4 mm and wall thickness is 0.3 mm to 1.5 mm. If you plan to produce larger or thicker tubes in the future, you should choose a larger model or request a customized production range.
