General Description
The proposed Tube Mill is a combination of equipment installed in a
line for the production of High FrequencyInduction Welded (HFIW)
carbon steel tubes. The process involved is cold forming of carbon
steel strip in circular shape,longitudinal welding, sizing,
converting into specified shape and cutting to pre determined
length. Ф165 high-frequency welded tube mill line is designed to
produce round tubes with diameter of Φ76～Φ165mm with wall thickness
of 2.0-6.0 mm and square/rectangular tubes of corresponding size.
This line utilizes roll forming to process steel strip into various
shapes. Using high frequency induction heating, this line is
capable of producing section material of various diameters and
sizes by squeezing weld seam together into closed shape.

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.
