I. Summary
The mill is intended for manufacturing round pipe Φ32mm-Φ89mm with thickness of 1.5mm-4.5mm 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.
Finished product will be of round, square or rectangular pipe
II. The 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 →→Flying saw under computer-control →→ Run-out table
Â
2.Is to roll the steel strip of different sizes to the corresponding tube blanks of straight seam continuously through roll type forming, cage roll forming and FF/FFX forming ,then heated the tube edges to the welding temperature via high frequency induction or contact heating and completed the welding under the extrusion of the squeeze roller, after cooling ,sizing and strightening to be the requested straight seam steel pipe. Mainly composed by the forming section, the welding section, the sizing section, the transmission system and the electrical system etc.

Q: What info you need before you make the proposal?
A: The pipe diameter and thickness range which you need or the profile drawings, material information, you special requirements.
Q: What I should do if I just start a new business?
A: Contact us immediately, we provide free consultant pre-sales service
Q: How do you do QA?
A: We have team do Strict QA
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 tolerance, Critical parts will be inspected for all dimensions
Q: Why I should choose you, what's the different between you and other Chinese supplier
A: We are concentrate on this area for more than 20 years. Our pipe making machine line directly export to US, Poland, Russia, Brazil, Egypt, Venezuela, El Salvador, Kazakhstan, Indonesia, etc.
Deep Stamping Products, it can also be called Deep Metal Stamping Parts, Deep Processing Metal Stamping Parts, or Deep Processing Stamping Parts.
The die used for stamping is called a stamping die, or stamping dies for short. A die is a special tool that processes materials (metal or nonmetal) into the desired parts in bulk. A stamping die is very important in stamping, without meeting the requirements of a stamping die, batch stamping production is difficult to carry out; Without advanced stamping die, the advanced stamping process can not be realized. The stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping processing, only they can be combined with each other to get stamping parts.
Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material-forming engineering technology.
Dongjie can produce stamping parts according to your drawings. Dongjie has more than 1500+ sets of molds and has a professional technical and design team. We can meet your requirements as much as possible. You are welcome to come to consult your drawings.
