New Installation Solution Easy Operation Round And Square Cold Rolled Steel Machine
ERW273 high-frequency longitudinal welded pipe production line/pipe making machine/tube mill is designed to produce welded pipes of 114mm-273mm in OD and 3.0mm-10.0mm in wall thickness, as well as corresponding square and rectangular pipe.
√ When producing round pipe, it can utilize ZTF forming technique
√ When producing square & rectangular tube, it can utilize directly square-square (DSS) technique

By Just Pressing the Button
Easy to restore rolls.
2.4-3% strip width shrinkage than round square forming method, so saving more raw materials
Simple abroach cold rolled section steel such as directly formed channel steel, C shaped steel, Z shaped steel. The rolls
can be basically shared with directly square forming technology.
This kind of mill can produce round pipe,square and rectangular pipe(direct to square or round to square) and some of
abroach cold rolled section steel.
1) ZTF Forming Technology Used In Produce Round Pipe
(1) Save 60% tooling cost
(2) Before the closed pore, one set of rolls can be used to produce lots of sized round pipe within the range. All the rolls
before this section can be shared use and no need to change.
(3) Limite production time and labor cost
(4) Easy to restore rolls
(5) Convenient to restore and adjust.
2) Directly Square Forming Technics In Produce Square&Rectangular Pipe
(1) Compared with ared with round to square forming technology, square to square technology can make better shapes of angles for cross section, smaller semidiameter of inner arcis, flatter brim, regular outlooks.
(2) Ease more burden of the whole production line, especially for the sizing section.
(3) 2.4-3% strip width shrinkage than round square forming method, so saving more raw materials
(4) By advance multi-point bending, avoiding the axial force and side abrasion, reducing the forming step and ensuring the
quality, meanwhile reducing power wastage and roll abrasion.
(5) By combined rolls, one set mould can be used to produce lots of square and rectangular pipes for different specifications.
This can decrease the storage of rolls, save 80% roll costs, fasten the bankroll turnover, shorten developing time for new lines.
3) Produce Parts Of Abroach Cold Rolled Section Steel
Simple abroach cold rolled section steel such as directly formed channel steel, C shaped steel, Z shaped steel. The rolls can be basically shared with directly square forming technology.

Q:How do you do QA?
A:We have special team do strict QA,this is our strengths:
(1)Every gear box will be tested for 8 hours with oil inside to guarantee there is no
(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
A:We are concentrate on this area for more than ten years.
Pre-sale:If the customer can not provide detailed technical information,our engineer
will go to the customer’s plant,draw precise drawings after measuring unit,to meet
your production requirement.
After-sale:Our strong team of engineers and experienced technicians can provide
you with installation instructions,operating instructions,quality control guidance
