Integration Risk in New Tube Mill Projects
Buying a tube mill is only half the job — the line must be laid out, installed and commissioned to actually produce. Buyers who receive only a machine are left to solve foundation, layout and startup problems themselves, delaying production and burning budget.
Why Machine-Only Deliveries Delay Startup
Without layout and foundation drawings, the buyer cannot prepare the site before the machine arrives. Without on-site commissioning, forming and welding settings are left to trial and error, so the line reaches rated output weeks later than planned.
The ZY20 Turnkey Tube Mill Line Solution
Every ZY20 ships with layout and foundation drawings, so you can prepare utilities and civil work before the machine arrives.
Engineer-led on-site installation and commissioning bring the line to rated production, with operator training to hand over a running mill.
A one-year warranty with spare-parts support protects the investment, backed by a complete φ10-26mm / 0.4-1.5mm line at up to 90 m/min.

Complete Continuous Production Process
Every ZY20 runs one continuous flow from coil to finished cut tube. An uncoiler feeds strip through a 7-roll precision leveler that removes coil-set, then double-radius forming shapes it in 5 rough and 3 finish stands without edge wave. A 100 kW solid-state HF welder fuses the seam under squeeze pressure with a dedicated seam guide, and an automatic outside-burr unit clears the bead immediately. ≥10 t/h spray plus overflow-pool cooling locks the shape, the 6-horizontal + 6-vertical sizing train sets the diameter, and a 4-roll Turk head straightens the tube before the microcomputer flying saw cuts 4–8m lengths to ±3mm. Overload-protected stands and 42CrMo hardened shafts keep the whole line stable over long runs.
Where the ZY20 Turnkey Tube Mill Line Is Applied
First-time tube producers and expanding mills that need a complete, ready-to-run φ10-26mm line with layout, installation and warranty support.
How to Select a Turnkey Tube Mill Line
Confirm the supplier provides layout and foundation drawings, on-site commissioning and warranty — the ZY20 includes all three. Match OD and wall to φ10-26mm / 0.4-1.5mm and size utilities from the drawings.
Installation, Support and After-Sales
The ZY20 ships as a turnkey package with layout and foundation drawings so you can prepare the site before delivery. Engineer-led on-site installation and commissioning bring the line to rated output, with operator training to hand over a running mill. A one-year warranty with spare-parts support protects the investment, and because the line accepts HR, CR and galvanized coil, you can adapt to changing material costs and market demand without re-tooling.
