Heat Transfer Expertise for Shell & Tube Heat Exchangers Optimizing the performance of shell & tube heat exchangers requires a detailed understanding of heat transfer mechanisms, fluid dynamics and fouling behaviour. NEOTISS combines precision tube manufacturing expertise with advanced heat transfer engineering to support exchanger designers during the tube selection phase. Our engineering teams evaluate how tube geometry, materials and surface characteristics influence the thermal behaviour of the exchanger. This expertise enables engineers to better understand how tube technologies impact heat transfer efficiency, pressure drop and operational performance. Through this technical support, NEOTISS helps engineering teams integrate high-performance tube technologies into their shell & tube heat exchanger designs. HTRI Thermal Simulations Using HTRI software dedicated to shell & tube heat exchangers, our engineers perform detailed thermal simulations to evaluate the impact of different tube technologies on exchanger performance. These simulations allow us to analyse: Heat transfer coefficients and overall thermal performance Shell-side and tube-side fluid flow behaviour Pressure drop constraints Fouling impact on heat transfer efficiency Performance differences between alternative tube geometries By combining HTRI simulation capabilities with NEOTISS expertise in precision tube technologies, we provide engineering teams with data-driven insights to support optimal tube selection.

FAQ – Tube Optimization for Shell & Tube Heat Exchangers

Why is tube selection important in shell & tube heat exchangers?

Tube geometry and materials directly influence heat transfer efficiency, pressure drop and fouling behaviour, which are critical parameters in heat exchanger performance.

How does a fin tube increase heat exchanger efficiency?

Generally, by increasing the surface available for heat transfer on the shell side and increasing turbulence on the tube side. Each case is specific and should be studied carefully.

What parameters influence heat transfer in heat exchanger tubes?

Key parameters include tube diameter, wall thickness, surface characteristics, tube material properties, fluid properties, process conditions, temperature, pressure, fluid velocity and fouling behaviour.

Can tube optimization improve an existing heat exchanger?

Yes. By adding additional surface area within an existing shell size, and in some cases making more efficient use of available pressure drop, performance can be improved through changes in tube type and bundle design.

When should I consider low-fin tubing?

See NEOTISS Technical Bulletin No. 2: View the Bulletin

Can I safely use low-fin tube in a fouling environment?

See NEOTISS Technical Bulletin No. 1: View the Bulletin

Can I safely use inner grooved tube in cooling water service or other tube-side fouling environments?

See NEOTISS Technical Bulletin No. 3: View the Bulletin

Can changing the tube type improve performance without redesigning the exchanger?

In some cases, yes. Performance can be improved by adding more surface area, changing the thermal conductivity of the material, optimizing wall thickness or modifying the tube ID. However, pressure drop and acoustic vibration must always be checked carefully.
