The advantage of a scheduled maintenance is to keep both thermic exchange and design temperature efficient
The dirt layer that piles up over time on the surfaces hinders the heat exchange and worsen the performances. For this reason, it is necessary to keep cleaned the surfaces.
In general, heat exchangers cleaning can be divided into two categories:
- Chemical washing;
- Mechanical and/or hydrodynamic washing.
One method does not exclude the other: it is possible, for example, to perform before a chemical washing and then a high-pressure cleaning.
Heat exchanger gaskets are subject to usury and substitute them before they get too damaged means avoid losses and serious damages, and, over time, it means costs and time saving.
During our maintenance activities, all gaskets are replaced with high quality gaskets, glued with a special non-hardening component, in accordance with the gaskets’ original technical specification that allow to avoid further thermal treatment, as vulcanization, that is however available on demand or for particular kind of gasket. This special kind of gluing that we use eases the following maintenance operation carried out on the plant.
The same of the tube heat exchanges.
In our cranckset replacement intervention we pay particular attention to the gaskets’ material that shall be used, as they shall be compatible with process fluids, with the plate kind and material, and with the technical features, as the pressure levels for which the exchanger has been designed.
Equipped with a highly qualified technical department, Nuova Saimar can offer a regeneration service of the whole exchanger, for example:
- Tube bundles, perforated flanges, baffles substitution;
- Plates substitution and / or repair in whatever material;
- Accessories (tie rods, nozzles, flanges) substitutions;
- Pressure test with certificated and calibrated pressure gauges;
- Non-destructing testing;
- Technical assistance for Recertification procedures
