The ERW tube mill machine is a core piece of equipment in the international welding tube manufacturing field. It produces electric resistance welded (ERW) tubes from steel strips with high precision. These tubes are vital for sectors like construction, automotive, and energy. Brands such as SANSO offer reliable ERW tube mill machines that meet global industrial standards.
An ERW tube mill machine manufactures tubes by forming and welding steel coils. It uses high-frequency current to create a strong bond along the seam.
This machine is common in tube mills for its efficiency. Key features include:
High-speed production capabilities
Consistent weld quality control
Flexibility in tube dimensions
In the welding tube sector, the ERW tube mill machine ensures durable output for various applications.
The ERW tube mill machine operates through a sequential process. Each stage is critical for tube integrity and performance.
First, steel strips are uncoiled and flattened. They then pass through forming rolls that shape them into a cylindrical form.
Next, the edges are welded using high-frequency induction. This method provides a seamless joint without filler materials.
After welding, the tube is sized, cooled, and cut to length. Modern ERW tube mill machines often include automated controls for accuracy.
Understanding the parts of an ERW tube mill machine helps in maintenance and selection. Each component plays a specific role.
Uncoiler: Feeds steel strips into the mill.
Forming Rolls: Gradually shape the strip into a tube.
Welding Unit: Uses high-frequency current to fuse edges.
Sizing Section: Calibrates the tube to precise diameters.
Cutting Tool: Cuts tubes to required lengths.
Regular inspection of these parts ensures the ERW tube mill machine runs smoothly. Brands like SANSO design machines with durable components.
Tubes from an ERW tube mill machine are used globally. Their strength and affordability make them popular.
