Hot Tension Reducing Steel Pipe

Due to restrictions by its production process, seamless steel pipe production costs have been high, resulting in the gradual decline of its economic benefits. As technology advances China's metallurgical industry, new products instead of seamless steel pipe hot stretch reducing began to emerge. Quality directly determines the quality of the weld pipes, ERW and seamless pipes is also the biggest difference lies. Longitudinal after the high-frequency welding, seam straight sets carbon can not be eliminated, but the weld interface together with the parent, and not completely fused into one, could not stand the test of time and pressure. Tension Reducing heat in the high-frequency welded pipe also carried out a process that no Longitudinal (online eliminate glitches table). Burr's presence will affect the flow of fluid within the tube, burr obstruct the normal activities of the fluid, then the occurrence of vortex. Based flow brawn learn the truth, will certainly increase the pressure part welds, discontinuity average so welded insurance factor is greatly reduced hot stretch reducing steel production process fully consider the risk of glitches exist, to limit eliminate glitches, Then make an average wall thickness, seamless appearance and undifferentiated. So from this point of view, hot stretch reducing pipe joints have completed the seamless transition. Reducing the overall thermal tension in the high-frequency welded steel pipes go through a heating temperature of 800 degrees, the overall annealing, and then open the transformation treatment, after this series of processes, the weld and the parent organization has the same performance, fully fused into one , well done from a seam to a seamless transition. Different processes resulting in a difference in product quality, and reducing thermal stress in the high-frequency welded pipe also carried out processes that are not conducted in a Longitudinal online clear internal and external burrs. Burr's presence will affect the flow of fluid within the pipe, blocking the normal flow of the stream glitches Neptune Casino body, resulting in a whirlpool. According to principles of fluid mechanics, welding inevitable partial pressure increases, the discontinuity makes pipe insurance factor is also greatly reduced, hot stretch reducing steel production process to fully consider the risk of glitches exist, to limit burr removal, thus so uniform thickness, no difference in appearance and seamless. So from this point of view, hot stretch reducing pipe joints have completed the seamless transition. Tension Reducing heat pipe on the basis of Longitudinal has conducted an online clearing internal and external burrs, 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, Longitudinal only limited water and low-pressure gas transmission environments.
