Product Description

ERW Steel Tube 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 seam welded pipe. It adopts high-frequency induction welding, which can not only produce round pipe but also corresponding square pipe and special-shaped pipes. The high-frequency pipe welding machine is mainly used for the production of various iron pipes, construction pipes, structural pipes, water pipes, oil pipes, API Pipes, and so on.



ZTZG was established in 2000, with 20 years of design and manufacturing experience. We are:

We have the honor to get 10 plus letters patent, China Cold-Formed Steel Technology and Equipment Innovation Award, and numerous other honors.

The straight seam welded pipe production line uses roll forming theory to gradually shape the strip steel into a billet tube, then through Kelvin effect and proximity effect of the high frequency current to heat up the welding line, letting it reach the welding temperature and finish the welding. A scraping device will then cut off the extra burr created during the welding phase, and the heated tube will go through the process of water cooling which lowers the tube temperature to standard degrees. Next, another round of roller-sizing will further shape the tube size and thickness and let it reach the desired diameter or dimension. Lastly, the tube will go through a rough straightening process through Turkshead and finally come out as the finished product.

Mainly used in the production of round pipe, oval pipe, and rectangular pipe.

Applications of pipe: Construction, Automotive, General Mechanical Piping, Furniture, Agricultural, Chemical, Petroleum, Gas, Pipeline, Structure, Scaffold. In the field of furniture, construction, municipal facilities, and others.



Main advantages:

High production efficiency: we choose trusted brand H.F. weder, ensuring the pipes are welded with high speed and almost no waste of steel material. Our roller stands are stronger and is made by casting iron, so the precision is highly secured. Beside, the service life is longer.
Highly automated
High strength, high speed, and stable operation improve product quality
Reduce production losses
Save roll changing time
Low wear of rollers

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.
