The HG60 welded pipe unit should be as close as possible to the position of the extrusion roll. The internal stress of the steel pipe is small and evenly distributed, which can effectively prevent stress corrosion cracking, and the dimensional precision is high, which is convenient for on-site welding construction. If the induction ring is far away from the extrusion roll, the effective heating time is longer, the heat affected zone is wider, and the weld strength decreases. On the contrary, the edge of the weld is not heated enough, after extrusion forming bad input heat is insufficient, the heated edge of the weld can not reach the welding temperature, the metal structure still remains solid, the formation of not fused or not welded through; When the input heat is insufficient, the edge of the heated weld exceeds the welding temperature, resulting in overfiring or melting drops, so that the weld forms a weld hole. Impedance is a magnetic bar or a group of special welding pipe, the impedance of the cross-sectional area should be not less than 70% of the inner diameter of the steel pipe, its role is to make the induction ring, tube blank weld edge and magnetic rod form an electromagnetic induction circuit, produce proximity effect, eddy current heat concentrated near the edge of the tube blank weld, so that the tube blank edge heating to the welding temperature. Adopt the process of pre - welding after fine welding, the welding process is stable and the weld quality is high. The direct-seam welded pipe equipment is dragged in the pipe blank with a steel wire, and its central position should be relatively fixed close to the center of the extrusion roll.
Hebei Yongyue Electromechanical Equipment Co., Ltd. is a professional high-end cold-bending equipment manufacturer with an annual output of 100 sets of equipment, integrating independent research, production, development, sales and service.
Q: Are you manufacturer?
A: Yes, we are manufacturer. We have our own technical team. Welcome to visit us.
Q: What payment terms do you accept?
A: We are flexible on payment terms, please contact us for details!
Q: What info you need before you make the proposal?
A: The pipe diameter and thickness range which you need or the profile drawings, material information, your special requirements and speed of the machine.
Q: How do you do QA?
A: We have special team do strict QA, this is our strengths:
(1)Every gear box will be tested for 8 hours with oil inside to guarantee there is no leak.
(2)Every shaft will be inspected for the centering jumpiness.
(3)Every roller will be checked to make sure its in the range of tolerance critical parts will be inspected for all dimensions.
Q: Why choose you? What is the difference between you and other Chinese supplier?
A: You can get higher quality product & better professional service from YONGYUE with same price.
Q: What I should do if I just start a new business?
A: Contact us immediately, we provide free consultant pre-sales service
