Slited coil is uncoiled and feed into forming section passing through the equipment of entry section. Entry section enables tube mill to run continuously by using strip joining and accumulator. Before welding, pipe is formed in round shape passing through a series of driven and idler rollers of forming section. In welding section pipe is longitudinally welded by using high frequency induction welding method. Outside bead is removed and formed in shape of scrap. The weld seam is ironed and pipe passes through the cooling section. Then in sizing section, pipe is formed to specified size and converted into specified shape. After sizing, pipe is cut to required length by using flying saw cut off equipment and delivered to collecting table after passing through run out conveyor..

Some of the features that make ERW pipe production line broadly appreciated and accepted include robust construction, high precision, low change over time and stable production.
ZTZG provides a balanced line plan by working with our partners in the world to design an entire ERW pipe production line. We not only develop external market but also strengthen our internal management. We especially establish a local area network and create fund flow, material flow, and information flow software for our company. If you are interested in ERW pipe mill, hydrostatic testing machine or other machines, please feel free to contact us.
The technical flow of the production line:
Scrolling up→ Uncoiling → Shear and Welding→ Spiral accumulator→ Forming → H.F. induction welding→ External burr removing→ Cooling → Sizing→ Flying saw → Run out table →Inspecting→ Packing→ Warehouse
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.
