API pipe mill is specialized for manufacturing straight welded pipe for petroleum and gas pipelines. Taking hot-rolled steel as raw material, it produce required pipes through cold roll forming and suitable welding methods like H.F. welding, submerged arc welding and so on. The whole production line adopts ‘ZTF’ forming technology.
Designed for the most precise fabrication of cold/hot-rolled coil, galvanized coil.The ERW pipe mill machine can provide the tightest tolerances for production.Produced round/square/rectangle pipe can be used at metllurgy, construction, transportation,machinery, automobile industry and more
ERW pipe mill is used to produce API, EN,ASTM,GB/T etc pipe to transport water, gas and oil, also can produce construction pipe.

Steel Coil → Double-arm Uncoiler → Shear and End Cutting & Welding → Coil Accumulator → Forming (Flattening Unit + Main Driving Unit + Forming Unit + Guide Unit + High Frequency Induction Welding Unit + Squeeze Roller) → Deburring → Water Cooling → Sizing & Straightening → Flying Saw Cutting → Pipe Conveyor → Packaging → Warehouse Storage
ZTF is a forming technique developed by ZTZG in 2005. It allows the shared-usage of rollers during break-down section when forming pipe, saving significant mould and labor cost while greatly improving production efficiency. It earns the reward of technology Innovation Award' by 'China Cold Forming Steel Association9 in 2010. After absorbing advanced pipe making technology from both abroad and domestic, our innovative designed production line and each single unit of the production line are not only economical but also practical.
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.
