Tube Conveyor Line Petroleum And Gas Oil Casing High-Grade Steel
Pipe API 5L Standard Tube Mill
Product Introduction
High-frequency welded pipe machinery is the production of low
carbon low alloy steel material welded pipe special equipment, the
specifications of the steel belt feeding machine will do the trick,
by forming roller steel with curled up into a tube, then using
high-frequency proximity effect and skin effect for tube side heat
quickly to welding temperature, and under the squeezing roller
extrusion complete welding, then through cooling, Sizing and
roughing to the required size of steel pipe. The company's roll
forming unit, FFX forming unit, roll row forming unit can produce
X80, J55 API oil casing, oil and gas pipe, in line with API-5L,
API-5CT and other
ZTF advantages:
(1) Save 60% roller cost per specification of desired product.
(2) Eliminate production down time for break-down forming section
roller replacement (typically 1-2 days per roller replacement).
(3) Electric controlled with high automation level.
Higher precision and faster roller change speed.

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.
