Low Carbon Steel Api Tube Mills
The whole production line adopts "ZTF forming technology which is developed by ourselves combined with advanced Japanese FFXtechnology. ( lt is no need to change rollers in the breakdown section) API tube mill is specialized for manufacturing welded tubes for petroleum and gas tube lines. Taking hot-rolled steel as raw material, it produces required tubes through cold roll forming and suitable welding methods like H.F. welding, submerged arc welding, and so on.
Successfully manufactured China's largest straight seam APl tube production line with Max OD 720mm
Apply to high strength steel and thickness
ZTF forming process save roller up to 60%

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. Our innovative designed production line and each unit of the production line practical.
