Spiral Tube Forming Machine PD-1600
Last updated: October 14, 2026
Fixed-mould spiral tubeformer with optional plasma cutting. Produces spiral ducts from 100mm to 1600mm diameter in 0.4-1.2mm strip — the mid-range workhorse of the PREDA spiral tubeformer family.
Technical Specifications
What is a Spiral Tube Forming Machine PD-1600?
A spiral tube forming machine rolls narrow strip into a helix and closes the spiral seam to produce round duct. The PD-1600 is the fixed-mould mid-range model: it produces duct from 100mm to 1600mm diameter in 0.4-1.2mm strip, with roller cutting attached and plasma cutting as an option. Fixed moulds give consistent seam geometry across the whole diameter range.
Key Features
- Produces spiral duct 100-1600mm diameter from 137mm strip
- Handles 0.4-1.2mm material — galvanized, stainless and aluminum
- Working speed 1-38 m/min across the diameter range
- Attached roller cutting; plasma cutting optional
- Fixed-mould construction for consistent seam geometry
- Coiler capacity 1200kg for continuous production
Spiral Duct Demand Across the Full Diameter Range?
Small shops make small diameters; big shops make big ones. Most fabricators need both — and buying two machines doubles the investment and the floor space.
The PD-1600 covers 100mm to 1600mm in one machine: strip in, spiral duct out, with the speed range (1-38 m/min) to run small diameters carefully and large ones fast.
How It Transforms Your Production Line
The Spiral Tube Forming Machine PD-1600 works on a proven principle — here is the step-by-step workflow that makes it possible:
Strip Feeding
Narrow strip (137mm feeding width) is fed from the coiler into the forming rollers.
Spiral Forming
Fixed-mould rollers form the strip into a helix at the set diameter.
Seam Closing
The spiral seam is closed as the tube forms — the lock seam runs continuously.
Cutting to Length
The attached roller cutter cuts to length; the optional plasma system handles thicker material and on-the-fly cutting.

Problems Solved: Before vs. After
We asked HVAC fabricators about their biggest production headaches. Here is how this machine directly addresses each one:
| Without This Machine | With This Machine |
|---|---|
|
✕ Diameter gaps
Small machines cannot reach large diameters and vice versa |
✓ 100-1600mm range
One machine covers the standard duct diameter range |
|
✕ Seam inconsistency
Adjustable setups drift; seams vary batch to batch |
✓ Fixed moulds
Consistent seam geometry every length |
|
✕ Cutting limitations
Roller-only cutting struggles with thick or fast work |
✓ Roller + plasma option
Attached roller cutting, plasma for thicker material |
|
✕ Coil change downtime
Small coilers stop production to reload |
✓ 1200kg coiler capacity
Continuous production through coil changes |
