3 PE Large Scale X70 High Grade Steel Pipe High Frequency Induction
Welding API Tube Mill
Product Introduction
This API production line is specialized for manufacturing straight
welded pipe for petroleum & gas, construction, metallurgy,
transportation, machinery, and vehicle industries. Taking
hot-rolled steel as raw material, it produces required pipes
through cold roll forming and H.F. welding. The whole production
line adopts “ZTF” forming technology which is developed by
ourselves.

Theory
The flexible Forming method is used in this pipe mill. Do not need
to change rollers in the breakdown section. The structure is more
simple and strong, so the operation and Maintainance are easy. The
mill is seldom going wrong.
Technology
ZTF is a kind of forming technology developed by Zhongtai Company
in 2005, which absorbed the advanced technology from both domestic
and international and then earn the “Technology Innovation Award”
by China Cold Forming Steel Association.
Application
The API pipe mill is used to produce standard API pipes. They can
be used for the extraction or injection of gas, oil, water, steam,
etc., and can be classified as casing or tubing, depending on the
application. The casing is used as a protective layer to help the
well resist internal or external contaminants for durability.
Tubing is used to inject or extract oil.

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.
