Legalization of Heat Exchangers

Project Description
Design, thermal calculation, and legalization of shell and tube heat exchangers for demanding industrial applications. Projects cover everything from mechanical conception to the issuance of the homologation files necessary for compliance with pressure equipment safety regulations.
Industrial Sector
Heavy Chemistry and Pharmacy.
Technological Challenge

The main challenge lies in managing highly sensitive products (corrosive, toxic, or flammable) operating under limit temperature and pressure conditions. Total chemical compatibility must be guaranteed through the selection of special materials, and structures must be designed to withstand thermal expansion without loss of leak-tightness. Additionally, adapting the constructive ideas of specialized boiler shops into a certifiable design requires extreme rigor in calculating thicknesses and welded joints.

Development

Mechanical dimensioning was conducted following international design codes (such as ASME VIII or EN 13445) for tubular exchangers, selecting the most appropriate alloys for each process. Development includes creating detailed construction plans with SolidWorks and preparing all documentation for the issuance of homologation files (CE Marking). Simultaneously, engineering participates in technical prescription and plant integration of plate heat exchangers, optimizing utility circuits (steam, glycol water, thermal oil) to maximize exchange efficiency.

Result
High-reliability thermal exchange equipment has been delivered, fully legalized and prepared for uninterrupted service in critical environments. Close collaboration with boiler shops has enabled the transformation of complex designs into manufacturable and safe realities, reducing the client’s operational risks and ensuring strict compliance with current regulations (Pressure Equipment Directive).
