Product Description

ERW 200x200 Square To Square Construction Pipe Steel Pipe Production Line

General Description

DSS technique directly reel the strip steel into desired sized tube with  several distinct advantages.It  adapts the multipoint bending  method,which avoids the axial force and side abrasion,reduces the forming step,and ensures high quality.Compare to Round-to-Square(RS)forming technique,DSS creates better outer edge and smaller inner arc for the cross section of the tube,and the brimis flatter with more regular outlook.With our new DSS-3 technique,only one set of rollers is needed for the entire mill with no need for any roller or spacer replacement,which achieves full-automatic adjustment for roller positions,significantly increasing production efficiency and reducing labor cost and risk of hazard.

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.
ur, innovatively designed production line and every single unit of the production line are economical and practical.
