Advantage of Sprial Steel Pipe

Determines the structure of the spiral steel pipe is superior features in areas such as power, chemical, oil and nuclear industry is becoming more and more widely used. Spiral pipe technology research has involved flow pattern and pressure drop characteristics research, strengthening heat transfer research various aspects, such as Hunan Great Steel Pipe Co.,Ltd-- large diameter spiral steel pipe manufacturer.

spiral steel pipe technology in many fields of chemical industry such as heat transfer and mixing get extensive application, good results are obtained. But the spiral pipe technology application in mass transfer separation until now still less. In recent years, many researchers in hebei province of large diameter spiral steel pipe factory in hebei province of large diameter spiral steel pipe manufacturer will spiral pipe technology used in micro filtration, nanofiltration, penetration and hollow fiber membrane in the membrane distillation and mass transfer separation process, has achieved good results because the spiral tube can form inside the pipe and tube axial vertical secondary flow, the secondary flow and axial mainstream compound into a spiral of forward motion for laminated circulating fluid, so it is not just rely on radial diffusion of fluid, and the effect of the radial secondary flow, the equivalent of the boundary layer on the damage, update the mass transfer surface. To enhance the mixing of fluid in the laminar flow movement, improve the effect of mass transfer. Spiral tube will also improve the outflow of tube type, namely the shell liquid flow pattern. Increase the radial mixing tube outside the liquid, reduce the number of shell side flow and the dead zone, at the same time because of the close to cross-flow, mass transfer of fiber surface constantly updated, the mass transfer coefficient of shell side will further increase of large diameter spiral steel pipe manufacturer in hebei. Herein lies the spiral steel pipe general superiority. But it is in many practical applications and other special function.
