Product Description

Factory direct sales Large Diameter Steel Rule Pipe Tube Mill Machine With API Standard Production Line





Zhongtai company has strong technical force and R & D capabilities, creating 7 China’s first:

China’s First Directly Square to Square Straight Welded Pipe Production Line.

China’s First ‘ZTF’ Forming Method’ Welded Pipe Production Line.

China’s First Multi-functional Welded Pipe Production Line.

China’s First Broad Steel Sheet Pile Equipment.

China’s First Stainless Steel Production Line Specialized for Railway Rail.

China’s First API Pipe Production Line for High Grade Steel.

China’s First Stright Welded API pipe production line with max OD 720mm.


ZTF-3 Forming Technique:


Only one set of roller is needed to produce all round pipe range from Φ273mm to Φ508mm during breakdown section (section before closure roll stands, weight around 60% of the entire mill rollers). When producing different sized pipe, only change rollers during fin pass section (section after closure rolls), therefore saving significant roller cost and increase productivity. The 3rd generation ZTF technique (ZTF-3) allows full automatic adjustment of roller position during break-down section with minimum to none need of manual adjustment, reducing labor maintenance cost and risk of hazard.




(1) Save 60% roller cost per one size of desired product.

(2) Eliminate production down time for break-down section roller replacement (typically 1.5-2 days needed per roller replacement).

(3) Electric controlled with high automation level

(4) Higher precision and faster roller change speed

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.
