Features of the pipe line: two motors are automatically matched in speed, and gear box are adopted to enhance the torque force of transmission; vertical supports are taper roller bearing and needle bearing; 1*2 positioning sleeve can realize fast mold change and improve the precision of tube making.
This VZH-168 tube mill line was delivered for the production of construction pipe, round pipe 76.2~168mm, wall thickness 1.5-6.0 mm. Square tube 60*60~130*130 mm, wall thickness 1.5-5.5 mm.
This production line is delivered for the production of galvanized pipes with round pipes of 25.4~79.2mm and wall thickness of 1.0-3.5 mm. Square tube 20*20 ~60*60 mm, wall thickness 1.0 ~ 3.0 mm.
How the drive and tooling are built
Two motors are matched automatically in speed and drive through a gearbox, which raises the torque available for heavier sections. The vertical supports use taper roller and needle bearings, and a 1x2 positioning sleeve allows a fast mould change while holding the precision of the tube being made.
Lines delivered on this design
Two delivered lines built on this design cover quite different sections, which is the range the mill has to be matched against:
Item | Line A | Line B |
|---|---|---|
Product | Construction pipe | Galvanized pipe |
Round pipe (mm) | 76.2~168 | 25.4~79.2 |
Square tube (mm) | 60x60~130x130 | 20x20~60x60 |
Round wall thickness (mm) | 1.5~6.0 | 1.0~3.5 |
Square wall thickness (mm) | 1.5~5.5 | 1.0~3.0 |
Frequently asked questions
What pipe range has this design been built for?
From 25.4~79.2 mm round pipe on the smaller of the two delivered lines up to 76.2~168 mm on the larger, with square tube from 20x20~60x60 mm to 60x60~130x130 mm.
What wall thickness can it run?
1.0~6.0 mm across the two delivered lines: 1.0~3.5 mm round on the smaller line and 1.5~6.0 mm round on the larger.
Why use two motors rather than one?
The two motors are matched automatically in speed and drive through a gearbox, which is what raises the torque available for the heavier sections in this range.
What bearings do the vertical supports use?
Taper roller bearings and needle bearings.
How is the mould changed?
With a 1x2 positioning sleeve, which allows a fast mould change and supports the precision of the tube being produced.
What to send for a quotation
The mill is built to the pipe you intend to produce, so these are needed first:
- Pipe section and size range — round, square or rectangular
- Wall thickness, minimum and maximum
- Material and whether the pipe is galvanized
- Required line speed in m/min
- Coil width and coil inner diameter
- Power supply at your site, voltage and frequency
