ERW Steel Tube Line High-Frequency Straight Seam Welded Pipe ERW
Tube Mill
Product Introduction
High frequency welded pipe production line is mainly used for
continuous production of straight seam welded pipe. It adopts
high-frequency induction welding, which can not only produce round
pipe but also corresponding square pipe and special-shaped pipes.
The high-frequency pipe welding machine is mainly used for the production of various
iron pipes, construction pipes, structural pipes, water pipes, oil pipes, API Pipes, and so on.
Technology
ZTZG was established in 2000, with 20 years of design and
manufacturing experience. We are:
We have the honor to get 10 plus letters patent, China Cold-Formed Steel Technology and Equipment Innovation Award,
and numerous other honors.
Theory
The straight seam welded pipe production line uses roll forming
theory to gradually shape the strip steel into a billet tube, then
through Kelvin effect and proximity effect of the high frequency
current to heat up the welding line, letting it reach the welding
temperature and finish the welding. A scraping device will then cut
off the extra burr created during the welding phase, and the heated
tube will go through the process of water cooling which lowers the
tube temperature to standard degrees. Next, another round of
roller-sizing will further shape the tube size and thickness and
let it reach the desired diameter or dimension. Lastly, the tube
will go through a rough straightening process through Turkshead and
finally come out as the finished product.

Application
Mainly used in the production of round pipe, oval pipe, and
rectangular pipe.
Applications of pipe: Construction, Automotive, General Mechanical
Piping, Furniture, Agricultural, Chemical, Petroleum, Gas,
Pipeline, Structure, Scaffold. In the field of furniture,
construction, municipal facilities, and others.
Advantage
Main advantages:
High production efficiency: we choose trusted brand H.F. weder,
ensuring the pipes are welded with high speed and almost no waste
of steel material. Our roller stands are stronger and is made by
casting iron, so the precision is highly secured. Beside, the
service life is longer.
Highly automated
High strength, high speed, and stable operation improve product
quality
Reduce production losses
Save roll changing time
Low wear of rollers
ZTZG Company Introduction
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.
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. Our innovative designed production line and every single
unit of the production line are economical and practical.
