Directly To Square ERW Welded Square Pipe Profiles Roll Forming Welding Line Machine

Directly To Square ERW Welded Square Pipe Profiles Roll Forming Welding Line Machine

“Directly to Square” forming Technology one complete set of combined rollers can make all the square and rectangular pipes, is economical and practical.

 

 Directly to Square forming Technology

one complete set of combined rollers can make all the square and rectangular pipes,  is economical and practical. The roll forming process takes square or rectangular pipes as one package of profiles between each other automatically adjusted by one set of combined rollers.

 

Directly to Square advantages:

Directly roll steel strip and form into Square& Rectangle, weld and then turks head to get finished pipes..  

1) Compared with round into square& rectangle forming, this way is better for the shape at the corner edge of cross section, pipe inner radius is smaller, and the brim is flat, outlook is good looking.

2) And the whole line load is lower ,especially the load on sizing is lower.

3) The width of steel strip is smaller about 2.4-3% than round into square & rectangle, saving material.

4) It adopts the multi-point bending way, avoid the axial force and side abrasion, reduce the number of forming steps under the same quality, meanwhile it reduce the power wastage and roller abrasion.

5) It adopts the combined type roller on the most of the forming stands, realize that one set of roller can produce dozens of square& rectangle pipes of different dimensions, thus decrease the storage of roller, saving cost about 80% on roller, the roller turnover becomes faster, one new product design time is shorter..

6) The high frequency welding happens on top of square / rectangular pipe top, the same as round pipe welding.

Process of Directly to Square pipe making:

Coil strip loading→ Uncoiling → Straightening end  Flattener →Strip Steel head - tail butt welding→ Accumulator→ Forming → High-frequency induction welding → Removing external burr→ Cooling→ Sizing → Cutting → Out roller table → Checking & Collecting→ Binding→ Weighing → Marking → Accessing Warehouse
