Process-specific thermal design

Custom Shell and Tube Heat Exchanger

A project-engineered shell and tube exchanger that balances thermal duty, pressure drop, mechanical conditions, material compatibility and maintainability.

Quick answer

What this equipment is designed to do.

A shell and tube heat exchanger transfers heat between two separated fluid streams: one flows through a tube bundle while the other passes around the tubes inside the shell. Each unit should be sized from the actual fluid properties, flow rates, temperatures, pressure limits, allowable pressure drop, fouling risk and cleaning strategy.

Shell and tube construction is selected for duties that need a robust pressure boundary, broad material flexibility or a serviceable tube bundle. The exchanger may operate as a heater, cooler, condenser, evaporator or heat-recovery unit depending on the phase behaviour and process objective.

Vessentra develops the thermal, hydraulic and mechanical design from a confirmed process datasheet. Shell arrangement, tube pattern, pass count, baffles, expansion provision, nozzles, supports and inspection access are coordinated as one engineered system. The applicable design code and documentation scope are agreed for the installation location and project.

Engineering configuration

Configured around your duty.

The equipment is developed from process inputs, operating conditions, cleaning requirements and site interfaces.

01

Fixed tubesheet

A compact configuration can be evaluated when the fluids and cleaning method suit a fixed bundle and thermal expansion remains manageable.

02

U-tube bundle

A U-tube arrangement can accommodate differential thermal movement and allow bundle removal, subject to tube-side cleaning requirements.

03

Floating or removable bundle

A removable-bundle concept can improve shell-side access where fouling, inspection or mechanical cleaning drives the maintenance strategy.

04

Materials and fabrication

Shell, tubes, tubesheets, baffles and gaskets are selected for corrosion, temperature, pressure, fabrication route and the agreed project standard.

Specification guidance

Common questions

Answers for project planning.

What information is required for a shell and tube heat exchanger quotation?

Provide fluid names and compositions, flow rates, inlet and required outlet temperatures, operating and design pressures, allowable pressure drop, physical properties, fouling information, preferred materials, cleaning method and installation location.

How do I choose between fixed tubesheet, U-tube and removable-bundle designs?

The choice depends on differential thermal expansion, fouling location, required cleaning access, leakage risk, fluid allocation, available maintenance space and project economics.

Which fluid should flow through the tubes?

Fluid allocation is decided from pressure, corrosion, fouling, viscosity, phase change, flow rate, cleanability and containment considerations. It should be confirmed during thermal and mechanical design.

Can the exchanger be designed for condensation or evaporation?

Yes. Phase-change duties can be engineered when vapour composition, pressure, heat load, liquid distribution, condensate handling and control requirements are defined.

Which design code applies?

The applicable pressure-equipment code and any TEMA or industry requirements must be confirmed from the destination, service and purchaser specification before engineering begins.
