200M/MIN HIGH SPEED ACCUMULATOR ZY16 TUBE MILL MACHINE Φ8-18MM HF WELDED PIPE

Problem

Every coil change that stops the line creates a weld seam defect on restart, wastes the tail end of strip, and turns high line speed into low real output.

Cause

Without strip storage, the forming and welding sections must stop whenever the uncoiler runs out, so the line spends production time ramping up and down instead of running at speed, and each restart leaves a cold or burnt seam.

Solution

The ZY16 accumulator stores strip at up to 200m/min, faster than the 90m/min forming speed, so it refills quickly and keeps the line running while a new coil is welded to the tail. Continuous feeding eliminates restart defects and recovers tail-end scrap, so the mill's rated speed translates into actual output.

Key Engineering Data

• 200m/min storage refills faster than the 90m/min line consumes.
• Continuous feeding removes stop-start restart weld defects.
• Recovers tail-end strip that would otherwise be scrap.
• Keeps the forming and welding sections running at speed.

Performance & Quality

The 200m/min accumulator is the key to continuous output: it refills faster than the line consumes, so coil changes never stop forming or welding. This removes restart defects and recovers tail-end scrap, making the ZY16's 90m/min speed a real, not theoretical, production figure.

Application

For uninterrupted Φ8-18mm tube production where coil changeovers would otherwise stop the line and create scrap and restart weld defects.

Selection Guide

Choose the accumulator option if your runs use multiple coils per shift. It pays back fastest on high-volume lines where every restart defect and stop directly costs output.

Application Scenarios

Continuous high-volume tube runs, thin-wall production sensitive to stop-start defects, and lines where tail-end scrap from coil changes is significant.

FAQ

Q1. What does the accumulator actually do?

It buffers strip so the forming line keeps running at speed while the uncoiler is stopped for a coil change, removing stop-start production.

Q2. Why is 200m/min faster than the line speed?

It refills the buffer faster than the 90m/min line consumes it, so the accumulator recovers quickly after each coil change and is ready for the next.

Q3. Does it prevent restart weld defects?

Yes, because the forming and welding sections never stop, there is no restart point to create a cold or burnt seam.

Q4. Does it need extra floor space?

The cage accumulator does add length to the line, but it is a standard configuration and we lay it out to fit your plant.

Q5. What happens if the accumulator empties?

In normal operation it refills faster than the line consumes, so it only empties if a coil change is delayed beyond the buffer's stored length.

Q6. What is the accumulator's stored length?

The stored strip length is sized to your line speed and coil-change time, typically enough for several minutes of continuous running.
