ERW 141 Low-Alloy Steel Esay To Operat Pipe Production Line
General Description
Intriduction
This 219 ERW Pipe Production Line is specially used for producing Φ 89-Φ 219mm, thickness 3.0-8.0mm high frequency straight seam welded
pipe and corresponding square pipe and special-shaped pipe(δ ≤ 6.0mm). The composition of equipment is from uncoiler to
computer-controlled fixed length cutting saw. Rolling speed can be
adjusted correspondingly within suitable range of pipe diameter and
wall thickness.

The technical flow of the production line:
Step1: Uncoiler
Uncoiler the function is to support and expand the strip, so strip
can enter into machine to roll forming. Strip can be expanded by hydraulic or pneumatic and uncoiler can be rotated 180 degree. Strip expand speed can be
adjusted, braking device designed with pneumatic or hydraulic
cylinder to press the brake rubber block
Step2: Shear & end welding
It is used to shear the head and the end of the steel strip of two
steel coils, cutting off the irregular part then welding two steel
strips, so machine can work continuously.
Step3: Accumulator
Installed between shear & end welder and forming mill, horizontal
spiral accumulator store a large amount of strip in a reasonable
footprint space to give enough time for shear & end welder to cut
and join the ends of two successive coils with non-stop tube mill
It has vertical cage type accumulator for small size tube mill
Step4: Forming
The function of this part is to make the steel strip become to the
tube blank by forming rollers
Step5: welding & scarfing
The function of this part is to center the welding seam and guide
the tube blank to welding device, so the welding seam will be
closed before welding, use scarfing tool to remove the burr to
ensure the smooth welding
Step6: Sizing
The function of this part is used to finish the tube blank from the
forming machine, so the tube size can meet the physical dimension
as customer required, form to square and rectangular and other
shape profiles
Step7: Straightening
4 rolls turk head straightening, straighten pipe online to achieve
the ideal flatness
Step8: Cut off saw
Cut off the pipe with required length, length of pipe can be set
With option of cold saw and flying saw
Step9: Run out table
This unit is to convey the finished pipe to packing, pipe transmit
by dynamic roll. A signal sensing device installed in the end of
run out table, when pipe touch the signal sensing device, it will
feedback the signal to control panel, control panel start working
and discharge the pipe
FAQ
Q: Are you a manufacturer?
A: Yes, we are a manufacturer. We have 4 factories ( Machining,
Assembling, Heat treatment, and Moulding ). We also have our own
R&D department. Welcome to visit us.
Q: What kind of payment term do you do?
A: We do T/T and L/C.
Q: What info do you need before giving me the price and proposal?
A: Since we design individual machines based on our customer's
requirements, we need your desired products' basic dimensions,
including all the pipe diameter(or tube length), thickness range,
usage, raw material steel grade, coil weight, and degree of
automation.
Q: What should I do if I just start a new business?
A: Contact us immediately, we provide a free consultant for
pre-sales service. Also, we can help you solve the raw material
(steel coil) purchase, worker training, international market price,
and more.
Q: How do you do QA?
A: We have a special team to do strict QA, this is one of our
strengths:
(1)Every gearbox will be tested for 8 hours with oil inside to
guarantee there is no leak.
(2)Every shaft will be inspected for centering jumpiness.
(3)Every roller will be checked to make sure it's in the range of
tolerance critical parts will be inspected for all dimensions.
Q: Why I should choose you? what are the differences between you
and other Chinese suppliers?
A: We are concentrating on pipe-making machines for more than 20
years. We have constructed many steady trading partners in Asia,
Africa, the Middle East, Europe, and South America throughout the
years.
ur, innovatively designed production line and every single unit of
the production line are economical and practical.
