Thermaline's double-tube, triple-tube, and multi-tube heat are widely used in the processing industry to process fluids with particulates, fibers and high viscosities. Thermaline's proprietary corrugation process is used to impress a heat transfer pattern the entire length of each tube creating an efficient heat exchanger. The corrugation depth and pitch can be altered according to the
Experimental studies on heat transfer and pressure drop Oct 01, 2015 · As seen in Fig. 9, the use of corrugated tube as the inner tube of the double pipe heat exchanger increases the friction factor of the annular space between the two tubes about 150190% while if both of the inner and outer tubes are corrugated, the friction factor of the annular space between the two tubes increases about 200254%. However, depending on the application the growth of
Thickness Of Inner Tube. 4 mm. Temperature. 50 - 200 deg.C. Pressure. 1 to 25bar g. Double Pipe Heat Exchanger has set of pipe in pipe arranged one above the other connected in series. One liquid passes through the central pipe and other liquid through annulus. USP of Nimotherm heat exchangers
Heat transfer enhancement in a corrugated tube heat The corrugated tubes are not afraid of defrosting and water stress, compensate linear expansion and can operate at temperatures up to 150 °C and pressure of 25 kg/cm2. These tubes are long service life due to the corrosion resistance and high tube strength and characterized by reliability and resistance to external and internal mechanical and hydraulic loads due to the material properties, high flexibility and
Jan 06, 2021 · As mentioned above, the corrugated tube has been investigated as a viable alternative to the passive enhancement method owing to its higher heat transfer performance. A DPHX with corrugation exhibits enhanced heat transfer and larger pressure drop of working fluid than DPHX with plain tubes.
Ultra-Corrugated Triple-Tube Heat Exchangers Advanced Application. Triple tube heat exchangers are ideal for viscous product processing or for direct regeneration heat recovery. Because of the unique nature of the units with media located both on the exterior and interior, and with the product running through a corrugated channel, heat transfer of more viscous products is optimized.
Numerical and experimental study of the heat transfer Dec 01, 2020 · They concluded that for the inner tube, the pressure drop for the corrugated wall heat exchanger was approximately two times higher than the smooth pipe. [ 41] performed a numerical simulation to study the effect of a modified corrugated on heat transfer enhancement.
Corrugated Tube Heat Exchangers SACOMESep 10, 2017 · Hygienic profile of corrugated tube heat exchangers . Similar drainability to a plain tube, as there are no dead zones. Different corrugation geometries for corrugated tube heat exchangers . HARD Corrugation. Allows to achieve a very high improvement of heat transfer coefficient which compensates the inherent increase in pressure loss. SOFT Corrugation. Intermediate between smooth tube design and tube corrugation HARD improving heat transfer to a lesser extent, but with lower pressure
