A tube mill machine is used to produce welded pipes, also known as longitudinal welded pipe machines. These machines are commonly used in steel pipe factories for producing various specifications of welded pipes. They are widely used in industries such as construction, automotive, and furniture manufacturing.
Uncoilers the hot-rolled steel coil and feeds it into the leveling machine. There are two uncoiling methods: upper uncoiling and lower uncoiling.
Ensures continuous production by trimming the irregular ends of the steel strips and welding them together.
Ensures the accuracy of the pipe’s outer diameter and cross-sectional shape, improving the stress concentration and residual stress from forming and welding.
Inspect the appearance and dimensions of the steel strip coil. Once confirmed, use the feeding cart to place the steel strip coil onto the uncoiler.
The prepared steel strip is fed into the machine through the uncoiler. The strip passes through the shear and end welder, welding the strip ends to create a continuous feed, minimizing downtime.
The accumulator stores the steel strip, ensuring a continuous and uninterrupted supply to the forming section.
In the forming section, the steel strip is gradually bent into a round pipe through a series of rollers.
The edges of the formed pipe are welded together using a high-frequency solid-state welder.
The welded pipe passes through the sizing section, where its diameter and roundness are precisely adjusted. The rollers on the stands adjust the pipe’s dimensions to meet the required specifications.
After sizing, the pipe is cut to the desired length by the flying saw in the cutting section.
The pipes are collected and stacked into the desired shapes for customers, undergoing quality and defect inspections. Pipes that do not meet the standards are removed for reprocessing or scrapping.
The production process of a tube mill machine is a complex and precise operation that requires careful attention to detail at every stage. From raw material preparation to final quality control checks, each step is essential for producing high-quality tubes and pipes. Understanding the tube mill machine process can help manufacturers improve efficiency, reduce waste, and ensure the production of superior products.
ERW seamless pipe, full name Electric Resistance Welding, is a steel pipe made by heating and melting the edge of the tube blank through the skin effect and proximity effect generated by the high-frequency current of the ERW Tube Mill Machine, and pressure welding under the action of the extrusion roller of the erw pipe machine.
ERW Tube Mill Machine adopts hot-rolled steel plate and then welded by high-frequency current. The weld is stress-eliminated by medium-frequency heat treatment, and the internal burrs are removed by an annular knife. Generally speaking, the cross section of erw steel tube is circular, the coating is mostly uncoated black tube, the connection method is welding, and it is suitable for high-pressure fluid transportation.

ERW seamless pipe is mainly divided into two forms: ERW AC welded steel pipe and ERW DC welded steel pipe. ERW straight seam welded pipe is divided into low frequency welding, medium frequency welding, ultra-medium frequency welding and high frequency welding according to the frequency. High frequency welding is mainly used for the production of thin-walled steel pipes or ordinary thick-walled steel pipes, and high frequency welding is divided into contact welding and induction welding.
1/High-precision pipe making process
ERW tube mill machine realizes ultra-precision processing through five-dimensional closed-loop control system, the deviation of welded tube outer diameter is ≤0.02mm, the deviation of ellipticity is ≤0.02mm, and straightness is
2/Roller quick change system
KINGREAL ROLL FORMER Tube Mill Making Machine adopts dovetail groove positioning + hydraulic locking structure, which reduces the time of changing rollers to 10 minutes, and the production recovery time is only 20 minutes. Equipped with RFID chips, the rolls can automatically recognize the specifications and retrieve the preset parameters, which reduces the error of manual calibration.
3/ERW Tube Making Machine is easy to operate.
ERW Tube Making Machine supports Siemens S7- series controllers, integrates 12 functional modules for welding, forming and cutting, and the operator interface supports Chinese/English/Spanish switching, which reduces the training period to 3 days.
4/ERW Tube Making Machine produces different shapes of products.
ERW Tube Making Machine can produce different shapes and sizes of tubes by replacing the rolls in the tube mill with high frequency ERW tube production line. A single ERW pipe mill production line can produce Φ8-630mm round pipe and 10×10-500×500mm square tube with wall thickness covering 0.5-20mm, and the material is compatible with carbon steel, low alloy steel and magnesium alloy.
