Product Description

ERW 273 H.F Welding High Strength Steel Pipe Making Machine API Tube Mill


The proposed Tube Mill is a combination of equipment installed in a line for the production of High FrequencyInduction Welded (HFIW) carbon steel tubes. The process involved is cold forming of carbon steel strip in circular shape,longitudinal welding, sizing, converting into specified shape and cutting to pre determined length.  high-frequency welded tube mill line is designed to produce round tubes with diameter of Φ48~Φ114mm with wall thickness of  and square/rectangular tubes of corresponding size. This line utilizes roll forming to process steel strip into various shapes. Using high frequency induction heating, this line is capable of producing section material of various diameters and sizes by squeezing weld seam together into closed shape. The products conform to BS/ASTM Standard. Adopting the advantages of the equipment of the same kind at home and abroad, each element of the line is designed with new ideas. The application of advanced technology, PLC automatic control system and British Eurasia Digital speed regulating unit ensure that the production line works reliably,operates and maintains easily. Being the best production line in China, it can also compete with the advanced ones in the world.

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.

(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 each unit of the production line practical.
