12000mm Automatic Straightening Pipe Making Machine Round And
Usually for big diameter and thicker pipe, after welding, the pipe
will be not straight and round, it will effact two pipes joint
together, therefore, with this straightening and rounding machine,
it can press the pipe to straightening and roundess. So our
machines are used in petroleum chemical equipment pipe ,gas reserve
facilities maintenance pipe; municipal engineering tube; electrical
instrumentation and automation engineering pipe; fire protection
engineering tube; anti-corrosion insulation engineering pipe;
environmental engineering tube; pressure vessel pipe, pipeline
maintenance tube; cleaning service pipe; petroleum chemical
I Steel pipe semi automatic straightening round machine technical
1 steel pipe plate thickness is from 10mm to 32mm.
2 Max straightening length is 2~12 meters, diameter: 500mm~1000mm.
3 maximum pressure: 600 tons.
4 advantages of this equipment is: minimize the crane using time;
the straightening and rounding completed in one machine; the roller
on the machine can adjust pipe circumferential position, high
efficiency and labor saving.
II: The whole machine working principle and composition:
1 working process description:
1.1 steel pipe straightening
A. Mount upper round tooling on the upper pressure head.
B. Lift the pipe on the two trolleys, trolley are located in the
two ends of the pipe.
C. When the pipe middle part is under the up press cylinder, start
the cylinder to straighten the pipe. And there is turning roller to
adjust pipe circumferential direction.
1.2 steel pipe rounding
A. Put the pipe on the trolley and lifting roller
B. Mount upper round tooling on the upper press head, and put the
bottom round tooling on the bottom press beam.
C. running the trolley, so that the pipe end is located in the
press head, start up the press cylinder to round the pipe. And move
forward the pipe to round the next part of pipe, according to this
way to round the whole pipe.
2 main components of equipment
A. main frame: Gantry type structure and the two sides’ column are
made in thick rectangular steel tube and plate. On the up press
beam, we install an upper press cylinder. At the bottom of this
cylinder, there is a mounting base, which is used to connect the
upper press tooling.
B. Forward and backward beam is welded structure, and we weld
rectangle rail on them, used for trolley running. And in the beam,
we weld two sets of turning rollers, and turning rollers are driven
by cylinder to move front and back, and turning rollers rotation
adopts hydraulic motor driven.
C. on the beam, there are two sets of trolleys, one trolley is
passive trolley, and the other one for the power trolley, on the
trolley, there are motor, speed reducer, and chain wheel. The
trolley through the chain transmission beam realizes running
forward and backward.
D. on the two sides of bottom press beam, there are two cylinders
driving roller device, to make the pipe out from bottom tooling
after rounding the pipe. At the bottom press beam, there is bottom
tooling mounting base, driven by cylinder, easy to replace the
E. hydraulic system: hydraulic pump is placed near the frame, is
composed of motor, pump, valve, pressure display, piping and other
components, oil pump with high pressure plunger pump, relief valve
with electromagnetic relief valve to control the oil temperature.
Valve chooses a stack of valves, with a simple structure, easy
maintenance. To control the hydraulic oil temperature, the electric
heater and the air cooler are arranged on the fuel tank.
F. Electrical control system: the trolley driving uses the
frequency conversion motor to control speed. All solenoid valves
are used in the DC 24V of the electromagnet. In order to ensure the
reliability of electrical control, all the electrical components
are used in the famous brand products.

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.
