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.
