10.1 Select Physical Property Input Method as start point)ĭT: only for printout DP: to calculate tubesheet thickness & bundle-to-shell clearance for pull-through floating head bundleġ0. Triangular tube-layouts result in better shellside coefficients and provide more surface area in a given shell diameter, whereas square pitch or rotated-square pitch layout are used when mechanical cleaning of tube outside is requiredĬut range: 5 – 30% For TEMA E Shell, No.Crosspass = No.Baffle+1Ĭut range: 5 – 30% Baffle cut (100*h/D): 17% to 35% of shell diameter A 22% cut is the optimum (HTRI) Baffle spacing:Ģ0% to 100% of shell diameter (HTRI recommends 40% of shell dia. Tube Pitch Ratio: 1.25, 1.333 are most common For kettle reboiler operating at low pressure, 1.5 pitch ratio has been proved effectiveĪ 30-degree layout (default) is most common. Practically, 16 ft or 20 ft facilitate reasonable plot space and maintenance for horizontal exchanger. Tube Length: In general, the greater the ratio of tube length to shell diameter, the more economical the exchanger.

1 inch tube are normally used when fouling is expected, or low ∆P is required.

Shell Selection depends on available ∆P, the E-type is the least expensive shell.ģ/4 ~ 1 in are more compact and more economical. Design You define most exchanger geometry and enough process conditions for Xist to calculate the required heat duty. Simulation You define exchanger geometry and fewer process conditions for Xist to calculate the required heat duty. Rating (Default) You define exchanger geometry and enough process conditions for Xist to calculate the required heat duty.
