The pipe coiling process requires specialized machinery to take the straight pipe and coil it, either ending up with one coil or multiple coils. Pipes of all kinds of lengths and diameters can be used for pipe coiling. Coiling pipes allows for some customization, from the bend diameter to the helix pitch.
Pipe coiling can be done by a few different machines, some of which require constant manual operation, while others are controlled by a computer for consistency. Either way, all of these machines are complex, but they are necessary for creating coiled pipes.
