Erw pipe making machine features:
The reason why ERW welded pipe is widely used is because of its unique characteristics, high dimensional accuracy, uniform pipe wall thickness, continuous operation, easy production, and comprehensive performance such as compression resistance, which has attracted more and more attention in the welded pipe industry. Other types of LSW are now slowly giving way to ERW. Especially in recent years, with the construction trend of West-East Gas Transmission, Western Development, and rural urbanization, the demand for ERW welded pipes will usher in a historic change. Let's analyze the characteristics of ERW welded pipe, spiral welded pipe (SAW welded pipe) and seamless welded pipe:
(1) Comparison of ERW welded pipe and spiral welded pipe (SAW welded pipe)
Spiral welded pipe, from its name, we can see that its weld is helical, while the weld of ERW welded pipe is straight. Therefore, the weld of spiral welded pipe is much longer than that of ERW welded pipe, and the welded seam of spiral welded pipe is much longer than that of ERW welded pipe. The internal welding flash is difficult to remove by technological means, so it will increase the resistance of the fluid when the material is transported. However, the weld seam of ERW welded pipe is short, and because its weld seam is straight, it is easy to be removed by technological means. This is of great benefit to fluid transport that heats up due to friction. At the same time, because the welding seam of the spiral pipe is long, the crack initiation and stress corrosion caused by the inner wall defects of the ERW welded pipe will increase compared with that of the ERW welded pipe. Under the same circumstances, its lifespan will be reduced.
(2) Comparison of ERW welded pipe and seamless welded pipe (SML welded pipe)
Relatively speaking, ERW welded pipe has advantages over seamless welded pipe in the following aspects: First, the diameter of ERW welded pipe has high precision, and the diameter and thickness deviation are smaller than those of seamless welded pipe, because ERW welded pipe has strip rolling and forming. It is easy to use process control, so the dimensional accuracy is relatively high. Secondly, the mechanical properties are relatively good, because the carbon content of the ERW welded pipe material is lower than that of the seamless one, so its flexibility and elongation are better than those of the seamless welded pipe. In addition, ERW welded pipe has high concentricity, uniform wall thickness and high collapse resistance. Because the ERW welded pipe is directly melted and recrystallized and sutured under the action of high-frequency resistance welding, no welding rod and other metals are added, and it has undergone strict heat treatment, so the performance of its weld seam and the performance of the original plate Basically the same.
Overall, ERW welded pipes are better than spiral welded pipes and seamless steel pipes in terms of size, flexibility, extrusion resistance, and quality of welds. In recent years, the forming and welding technology of ERW welded pipes has also improved. Therefore, we have reason to believe that it is the general trend that ERW welded pipes will replace seamless welded pipes, and the application of ERW welded pipes will become more and more extensive.
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 it is in the range of tolerance critical parts will be inspected for all dimensions.
