What the FG20/30 line is built for
The FG20/30 is a precision stainless steel cladding pipe mill. The two models are separated by tube diameter, wall thickness and main motor power rather than by welding speed, which is the same on both.
FG20 covers 8~25.4 mm tube with 0.3~0.5 mm wall on a 30 kW motor. FG30 covers 13~32 mm tube with 0.4~0.8 mm wall on a 37 kW motor. Both are listed at a tube welding speed of 10~35 m/min and both use 60 kW of high-frequency power.
Two items on the component list are prepared by the customer rather than supplied with the line: the shear and end welder, and the compositing machine.
Frequently asked questions
What is the difference between the FG20 and the FG30?
FG20 runs 8~25.4 mm tube with 0.3~0.5 mm wall on a 30 kW main motor. FG30 runs 13~32 mm tube with 0.4~0.8 mm wall on a 37 kW main motor. The welding speed is 10~35 m/min on both.
What tube size does the line cover in total?
8 mm to 32 mm diameter, with wall from 0.3 mm to 0.8 mm. The two models overlap from 13 mm to 25.4 mm, so tube in that band can be run on either machine.
Is the high-frequency power the same on both models?
Yes. Both are listed at 60 kW of high-frequency power and at a welding speed of 10~35 m/min.
Is the shear and end welder included in the line?
No. The shear and end welder and the compositing machine are both marked as prepared by the customer. The uncoiler, accumulator, main machine, rotating cutting saw and run-out table are supplied with the line.
What to send for a quotation
The line is built to specification, so the following are needed before the FG20 or FG30 can be quoted:
- Tube outer diameter and wall thickness range
- Strip material and strip thickness
- Whether the shear and end welder and the compositing machine will be supplied locally
- Coil width and coil inner diameter
- Required welding speed in m/min
- Power supply at your site, voltage and frequency
