Product Details

Automatic Steel Welding Production Line Pipe Tube Making Machine

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
Round pipe	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.
