Tube ERW Production Line High-Frequency Straight Seam Welded Pipe ERW Tube Mill

Product Introduction

High frequency welded pipe production line is mainly used for continuous production of straight welded pipe, using high-frequency induction welding, not only can produce round pipe but also can produce not more than the processing range of round pipe square pipe and shaped pipe

Process flow:

Uncoiling → leveling → accumulator → rolling forming → high-frequency welding → external burr scraping → cooling → sizing → straightening → flying saw cutting → blanking

XZTF round-to-square share-roller forming line

This technique is groundbreaking in pipe making industry.
It allows utilizing round-to-square forming when producing square/rectangular tube while sharing the break-down section and sizing section rollers for the entire line, achieving the high level of automation and accuracy as direct square forming while adopting round-to-square technique with better R pipe angles compared to direct square forming.
This new design is to better suit the future global pipe market. Currently, all the European region adopts only round-to-square formed pipe for steel structure and many regions and countries such as China are gradualy changing policies toward this because of the superiority of round-to-square tube in most building structures.
We have successfully manufactured and tested this technique in several locations in China, and they have stably functioned for more than 3 years. We would like to introduce this new technique to you to better benefit our valuable old customer.

Steel tube production line to certain specifications of the galvanized steel belt feeding machine, curled up into a tube by forming roller steel billet, and then use the high frequency of proximity effect and skin effect make the tube side quickly heated to welding temperature, and under the squeezing roller extrusion complete welding, and then through the zinc patching machine is to burn high frequency weld position to catch up on the zinc layer, then through cooling, Galvanized pipe to the required specification by sizing and rough straightening. Because the antirust cost of galvanized pipe is lower than the cost of other coatings; So the use is very wide, and durable general use of more than 20 years is no problem.

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.
