Zhongtuo high frequency steel pipe making machine adopts advanced welding technology and offers dual welding arcs, increased speed, higher deposition, superior mechanical properties and quality. It is widely applied for producing tubes for heat exchanger, refrigerator, frame of car, bicycle, fitness equipment, furniture, cooling machine, petrol transmission, construction industry, etc.
Now we have four types machines which are divided by wall thickness and diameter.
Applications listed for these machines
The page lists the tube markets these machines serve: heat exchanger, refrigerator, car and bicycle frame, fitness equipment, furniture, cooling machine, petrol transmission and construction.
Pipe range of the high frequency machines on this site
The straight-seam machines are divided by pipe diameter and wall thickness. The table below collects the range published on each model page, so you can see which model covers the pipe you need to run.

Frequently asked questions
What pipe sizes do these machines cover?
The straight-seam range published here runs from 7 mm to 25 mm pipe ID on the ZT-32, up to 50 mm to 165 mm on the ZT-165. The HG series covers larger diameters again.
How do I choose between the models?
The pipe outside diameter and wall thickness decide the mill size. The output required per shift then decides the line speed and the number of forming stands.
What are the tubes used for?
Heat exchanger, refrigerator, car and bicycle frame, fitness equipment, furniture, cooling machine, petrol transmission and general construction tube.
