Editing Tension Reducing Steel Pipe And Welded Steel Pipe

<br><br><br><br><br>After sizing the pipe diameter deviation is small, smaller ellipse, straight better, smooth surface.<br>In addition to reducing the role of sizing, but also to make the product specifications for the development of small caliber. Reducing the number of machine frame work more generally 9 a 24. Reducing mill is two or three roll vertical roll rolling mill, just rolling the hollow tube. <br>Quality directly determines the quality of the weld pipes, welded and seamless pipe is also where the greatest difference.<br><br>Longitudinal after high-frequency welding or submerged arc welding, seam straight sets carbon not eliminate, the weld interface together with the mother only,  [https://www.kynghidongduong.vn/tours/tour-trung-quoc-nam-ninh-truong-gia-gioi-phuong-hoang-co-tran-6-ngay.html kynghidongduong.vn] and not fully integrated one, could not stand the test of time and pressure. Tension Reducing heat pipe [ ] after about to go through a heating temperature of 800 degrees, the overall annealing, after this series of processes, weld performance close to the parent organization, well done from seam to seamless transition. <br>Different processes have resulted in differences in product quality, and reducing tension in the steel pipe welding process is also carried out by a Longitudinal no: the online clear internal and external burrs.<br><br>Burrs presence affects the fluid pipe-flow, blocking the normal flow of fluid burrs, resulting in the whirlpool. According to principles of fluid mechanics, welding inevitable partial pressure increases, the discontinuity makes pipe insurance factor is also greatly reduced, reducing the tension in the steel production process fully considered the danger exists burr, burr removed, thus making it uniform thickness, no difference in the appearance and seamless.<br><br>So from this point of view,  [https://www.kynghidongduong.vn/tours/tour-trung-quoc-nam-ninh-truong-gia-gioi-phuong-hoang-co-tran-6-ngay.html tour trương gia giới] hot stretch reducing pipe joints also completed a seamless transition from the course, the difference between the two is not just limited to the above two points, but suffice [ ] and also reducing tension there are significant differences.<br>The latter has conducted on the basis of Longitudinal online clear inside and outside burr, the overall heating type variable and a series of new processing technology, making it a qualitative leap, can generally be used in high pressure areas, [http://www.bing.com/search?q=Longitudinal&form=MSNNWS&mkt=en-us&pq=Longitudinal Longitudinal] generally used in water gas under low pressure environment for the delivery or steel.<br><br>Of course, the difference between the two is not just limited to the above three points, but suffice Longitudinal Tension Reducing heat pipe, there are still big differences. The latter has conducted on the basis of Longitudinal online clear inside and outside burr, the overall heating type variable and a series of new processing technology, so it has been a qualitative leap in the high pressure can be widely used in the field[ ], and straight stitch only limited water pipe low pressure gas transmission environments.
