ENGINEERED FOR CORROSIVE PROCESS DUTY
Silicon Carbide Tube-and-Shell Heat Exchanger
SHINEHEAT silicon carbide heat exchangers combine pressureless-sintered silicon carbide (SSiC) tubes with a project-specific shell, tube-sheet, sealing and lining system. The result is a compact heat-transfer solution for corrosive heating, cooling, condensation and evaporation duties.
Corrosion-resistant tube material
Dense SSiC offers broad resistance to many acids, alkalis, oxidizing media and solvents. Final compatibility must be checked against the actual process conditions.
High heat-transfer capability
High thermal conductivity supports efficient heat transfer while the low thermal expansion of SiC helps control thermally induced stress.
Maintainable sealing concept
Project-selected elastomer seals and an accessible tube-sheet arrangement support inspection and tube-by-tube maintenance.
Why pressureless-sintered silicon carbide?
Broad chemical resistance
Suitable for many highly corrosive fluids when the SiC grade, seals and other wetted materials are correctly selected.
Thermal stability
The combination of high thermal conductivity and low thermal expansion provides a strong basis for thermal-cycling service.
Hard, smooth heat-transfer surface
The ceramic surface provides strong wear resistance and can help reduce fouling tendency in suitable process conditions.
Material-selection note: corrosion performance depends on fluid composition, concentration, temperature, contaminants, velocity and cleaning method. Final selection is governed by the approved project datasheet and material review.
Typical process duties
Corrosive liquid heating and cooling
Corrosive vapor condensation
Evaporation and absorption service
Fine and specialty chemicals
Pharmaceutical process service
High-purity chemical duty
SHINEHEAT construction concept
Each unit is configured around the process chemistry, temperatures, pressures, allowable pressure drop, cleaning requirements and applicable design code.
Dual tube-sheet separation
The process-side and utility-side tube sheets are separated by a monitored interspace. This arrangement is intended to reveal seal leakage and reduce the risk of cross-contamination between the two media.
Individually adjustable tube seals
Each tube seal can be compressed and serviced independently. FKM, FFKM or another compatible sealing material is selected to suit the process fluid and temperature.
Corrosion-resistant chamber options
The tube chamber and other wetted components may use PTFE, PFA, enamel or other project-selected materials according to the corrosion and mechanical design review.
Spiral baffle support
A spiral baffle arrangement provides distributed tube support and promotes shell-side flow distribution. Final geometry is verified for heat transfer, pressure drop and vibration risk.
