Pipe making process:
1. Breach machine
What kind of breach machine we need is according to the quality of
custom’s product making. Finally we can recommend an economic and
useful one to suit you well then. What you see below picture is
about breaches for two sides for good next welding.
2. pre-bending machine
We need to get working piece pre-bend at two ends of plate as the
following picture for making a good pipe. Obviously there are two
ways to make it. One is pre-bending machine and the other is press
bake machine itself, but we don’t recommend the last way for the
big work piece for long time use. Because of big work piece and big
lateral force, it’s obviously easily to damage the machine.
For example, The following pipe finally made you see is without
pre-bending. I don’t think it is the right pipe you want. So
pre-bending is important to the pipe and what kind of machine is
used for pre-bending is important as well. It does have
relationships to pre-bending quality, work efficiency and so on.
3. CNC press brake machine
We need a press brake machine to finish this kind of pipe. Of
course, besides round-shape pipe, it also can make polygon pipe and
bend for any other angles as well. Obviously we will make this pipe
with many bending times. The size of seam is according to the
thickness of upper tooling holder. Thinner of upper tooling holder
and smaller seam.
4. Automatic Closing and Welding Machine
We need this kind of machine to get seam close and welding. See as
Gas shielded arc welding is at the bottom of outside seam first to
prevent seam opening. We don’t need to remove it any more. Because
it is different from submerged welding, no Submerged arc welding
5. Pipe inside Welding Machine
We need this kind of machine to weld the seam with Submerged
welding inside pipe. The machine is consist of welding trolley,
welding system, mechanic device, welding grounding device, inside
welding monitor system, welding flux feeding and recycle device,
and control system. Adopt trolley to move pipe, the welding gun
Finally it would be like following picture after Pipe inside
6. Pipe outside Welding Machine
We need this kind of machine to finish pipe outside welding as
7. Steel Pipe Straighten and Round straightening combined Machine
This kind of machine is used to make the steel pipe straight and
Regarding all kinds of machine details you have to contact Stacy
who is an expert on making a pipe. She has already offered many
successful solutions for different customers for different pipe.
