Underground Pipe HFW Welding Cold Rolled Steel Production Line
Machinery
Machine Introduce
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.
Equipment Technology:
√ When producing round pipe, it can utilize ZTF forming technique
√ When producing square & rectangular tube, it can utilize directly
square-square (DSS) technique

Forming Process
| Round pipe | Cold roll forming process | Good roller design |
| ZTF forming process | Save at least 60% roller cost with electric control adjustment |
| Square & rectangular tube | General round-to-square process | Stable forming process |
| Round-to-square with Turks head | Good pipe quality |
| Process of directly square-to-square(DSS) | One set of roller can produce all tubes with electric control and
automatic adjustment |
Machine Advantage:
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.
Technology Advantages
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.
FAQ
Q:Are you manufacturer?

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
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.
