The tube & pipe mill machine is an automation system to produce pipes, square tubes, shaped tubes for furniture, steel structures, hand rails, piping, heat exchangers and so on by slit coils(skelp). It can be divided into ERW(Electric resistance welding) type, TIG welding type and PLASMA-TIG welding type.
General process is same as below,
Composition
| 1. Decoiling |
Unrolling the winded skelp. |
| 2. Butt welding |
Connecting the both ends of skelp for the continuous production. |
| 3. Accumulator |
Stacking the connected skelp to decrease the material preparation time. |
| 4. Forming |
Passing skelp through the roll forming tool. |
| 5. Welding |
Welding process by electric resistance. |
| 6. Cooling |
Air and water cooling to uniformalize the heated organization after high frequency heat treatment process. |
| 7. Sizing |
To accurate the out diameter of pipe. |
| 8. Cut-Off |
Cutting to ordered dimension. |
| 9. Straightening |
Passing through the correction gap for the straightness. |
| 10. End facing |
Chamfering & beveling the cut side according customer’s order. |
| 11. Hydrostatic testing |
Checking the water leak and crack. |
| 12. Packing |
Packing by ordered. |
KINDUS, we fidelity to mill stand’s principles in manufacturing not only the main part but also the front and the rear part and do our best for the high quality by keeping the processing standardization and high accuracy.
