Carbon Steel Tube Mill Welded Duct Forming Machine ERW Steel Pipe Production Line
The mill is intended for manufacturing of round pipe of Φ114mm-Φ273mm with thickness of 3mm–10mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine, cooling, further sizing or shaping and on-stream cutting of endless tube in measured lengths.
Technical Flow Of The Production Line
SteelTape →→ Double-head un-coiler →→ Strip-head Cutter and welder →→ Spiral accumulator →→ Forming section (Flattening unit +Main driving unit +Forming unit +Guide unit +High frequency induction welding unit +squeeze roller) + De-burr frame →→ Cooling unit →→ Sizing unit and straightener →→ Cold saw under computer-control →→ Run-out table →→ Packing machine
√ When producing round pipe, it can utilize ZTF forming technique
√ When producing square & rectangular tube, it can utilize directly square-square (DSS) technique

1. uncoiler: 360º rotary hydraulic-pressure tight, which insure steel coil feeding altematively and make steel strip go into accumulator freely.
2. accumulator: It has two kinds of accumulator for optional. Usually big line use roller type, and small line use disc type.
3. forming part: mainly roughly mill-forming steel strip and controlling weld seam.
4. sizing part: mainly fine shaping pipe after welding and controlling pipe accuracy.
5. turkey's head: mainly used for straightening of finished pipe roughly online.
Q:Are you manufacturer?
A:Yes,we are manufacturer. We have 4 factories ( machining, assembling, heat treatment,and mould factory)And we have our own R&D department. Welcome to visit us.
Q:What kind of payment term you can do?
A: We can accept T/T and L/C.
Q:What info you need before you make the proposal?
A:The pipe diameter , thickness range , usage, raw material steel grade, coil weight and automatic degree.
Q: What should I do if I just start a new business?
A:Contact us immediately ,we provide free consultant for pre-sales service .Also we can help you to solve the raw material (steel coil) purchase,worker training,international market price.
Q:How do you do QA?
A:We have special team to do strict QA,this is one of our strengths:
(1)Every gear box will be tested for 8 hours with oil inside to guarantee there is no leak.
(2)Every shaft will be inspected for the centering jumpiness.
(3)Every roller will be checked to make sure its in the range of tolerance critical parts will be inspected for all dimensions.
Q:Why I should choose you,what are the differences between you and other Chinese suppliers?
A:We are concentrate on this industry for more than 20 years,and especially in pipe making machines. Our pipe making machine line directly export to Russia,Vietnam,lndia,Indonesia,and many other countries in Asia, Africa, middle east and South America.
