Pipe Forming And Welding Machine Welded Tube Bending Equipment ERW
Duct Mill
Product Description
Erw pipe mill machine: At first, the coil is loaded at the
uncoiler, then but-welding the ends of coil, delivering to
accumulator. After accumulator, the strip is pulled from
accumulator contentiously by fixed speed, is formed to opened-pipe
at forming machine, then welded by High frequency welder, deburred,
cooled, shaped and sized as round pipe and rectangular&square
pipe at the sizing area. Then the sized pipe is straightened after
Turkey-head device and then cutt to fixed length by flying saw. At
last, the fixed pipe is delivered from run-out table and inspected
at the table.
This line could produce the round pipe, the rectangular and square
pipe by material of cold/hot-rolled coil etc. It could be used at
the metallurgy, construction, transportation, machinery, automobile
industry. Adopting "W" forming type, it could make much more
reasonable force, and much more perfect forming shape at each stand
etc.

coil) purchase,worker training,international market price.
Q:How do you do QA?
A:We have special team to do strict QA,this is one of our
strengths:
(1)Every gear box will be tested for 8 hours with oil inside to
guarantee there is no leak.
(2)Every shaft will be inspected for the centering jumpiness.
(3)Every roller will be checked to make sure its 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 concentrate on this industry for more than 20 years,and
especially in pipe making machines. Our pipe making machine line
directly export to Russia,Vietnam,lndia,Indonesia,and many other
countries in Asia, Africa, middle east and South America.
