Octagonal Tube roll forming machine
What is Octagonal Tube?
As its name shows, Octagonal Tube is new type building material. Octagonal Tubes are widely used in petrochemical, power plant desulfurization, aerospace, ships, machinery, communications, electronics and other fields. In the market, there are two types Octagonal Tubes, seamless and interloacked. The seamless Octagonal Tube is also made by cold draw pipe making machine. Here I will mainly show the interlock Octagonal Tube pipe with the interlocked seam. Here are tube pictures for your refernece:
What is Octagonal Tube roll forming machine?
Octagonal Tube roll forming machine is mainly for making interlocked pipe of Octagonal shape by rolll forming principle. The pipe length could be specified in PLC system casully. But for the pipe diameter is only for 40mm. If you want to make other diameter pipe, you have to buy another set of molds.  Here are two sizes for your reference:

Now for the Octagonal Tube of diameter 40 and 60mm, we could design to make by one machine. By this way, if you are the interlocked tube producer it can save lots of investing cost. And we will use the flying cutting saw and no need to change the cutting baldes.

By the above Octagonal tube shape changing process, you can know how the tube is made from the strip.
