Spiral corrugated pipe (patent number: ZL*******3.6) is the company
and sinopec luoyang petrochemical engineering corporation jointly,
in horizontal stripes corrugated pipe on the basis of the study,
which focuses on horizontal stripes of corrugated pipe processing
and high cost, slow speed, parameters such as single faults, the
heat exchange tube processing into a spiral corrugated type, tube
flow resistance than horizontal stripes bellows, basically keep
horizontal grain strengthening heat transfer performance of
bellows, and greatly improved the corrugated pipe processing speed,
reduce processing costs.
Between July and September ***2 in xi 'an jiaotong university
national laboratory of multiphase flow and heat transfer of spiral
corrugated heat exchange tube and resistance performance research
experiment was carried out, which in turn for industrial
application.The
results show that the improvement is successful, achieve the
desired effect.
Spiral corrugated pipe processed by special equipment, and
annealing treatment.A
spiral corrugated tube bulge, when the fluid flows through the tube
stranded boundary layer is destroyed, the heat transfer effect than
light mind a lot, at the same time reduce the formation of scale
formation.Its
outside corresponding formation of the spiral corrugated pipe
surface, not only increase the heat transfer area is slightly also
promote the disturbance of the fluid, also to strengthen the heat
transfer effect.So
spiral corrugated pipe finally achieved the purpose of
strengthening heat transfer on both sides, compared with ordinary
light tube heat exchanger, tube in turbulence, the film heat
transfer coefficient is about 2.2 times the average aggrandizement,
pipe outside the film heat transfer coefficient improved about 1.5
times on average.The
total heat transfer rate more than *5% higher than that of ordinary
light tube heat changer, can reduce the heat transfer area of about
*5%, reduce equipment investment bring significant economic
benefits to the user.But
due to the roughness on the surface of the spiral corrugated pipe
is lower than the horizontal stripes bellows, compared with the
light pipe about double the tube pressure drop, shell pressure drop
increases about *5%.Spiral
corrugated pipe overall heat transfer effect of bellows about *0 ~
*5% lower than horizontal grain, but vortex tube pressure drop is
only about *0% of the horizontal stripes threaded
pipe.Thus
bring good economic benefits at the same time, also reduces the
manufacturing cost.
This product after son went public in ***4, by the end of ***5 the
product applied to petrochemical industry performance more than **0
units.CTHE
can complete process design calculation software for design,
production and manufacturing departments.
