Tension reducing the difference between steel pipe and Longitudinal Process

Different processes have formed a production quality differences, reducing tension in welded steel pipe also stopped a straight seam welded pipe Friends of the process is not stopped: online eliminate internal and external burrs. The existence glitch affects tube fluid - flow, glitches obstruct the normal activities of the fluid, resulting whirlpool. Based on principles of fluid dynamics, weld some pressure must increase, the average discontinuity of the Friends of the pipe safety factor is also greatly reduced, stretch reducing pipe processing technology to fully reflect on the existence of the risk of glitches, stop burr elimination, making it an average wall thickness, seamless appearance with no difference.

Resolution of the weld quality is directly YHI pipe quality, but also where the biggest difference between pipe and seamless. Friends of straight seam welded pipe at high frequency welding or submerged arc welding, the carbon can not be set straight seam eliminate the weld interface in conjunction with the parent only, and not a complete blend of one, could not stand the test of time and pressure. Tension Reducing heat welded steel pipe in the pipe even after high temperature of about 800 degrees after heating, the overall annealing, after this series of processes, the weld performance close to the parent organization, well done seamlessly from seam to transition. So from this point of view, hot stretch reducing pipe joints from having also completed a seamless transition, of course, the distinction between the two is not only limited to the above two points, but enough to clarify YHI straight seam welded pipe and tension reducing pipe there are still significant differences. Longitudinal bedrock on the latter has ceased online eliminate burrs inside and outside, the overall heating type variable and a series of new technologies disposal, so that it has been a qualitative leap in the high-pressure areas can be commonly applied, straight seam Friends fat pipe used in low pressure environment of ordinary water gas walks or for steel construction.
