Micro-residue continuously erodes and wears down the tube walls

Fine filter residue flows at high speed with the circulating fluid, repeatedly impacting and rubbing against the inner walls of the heat exchanger, gradually thinning the passivation layer and causing microscopic scratches.

Particle adhesion and deposition form a scale matrix

Filter residue becomes lodged in the irregularities of the tube walls and accumulates in the boundary layer, acting as a framework for the adhesion of salts and colloids, accelerating scale formation and thickening, and increasing the thermal resistance of the heat exchanger.

Inducing localised pitting and crevice corrosion

Gaps form where the residue adheres to the metal wall; these areas experience an accumulation of corrosive ions such as chloride ions and low oxygen levels, triggering crevice corrosion and pitting.

Blockage of flow channels alters flow distribution

The accumulation of fine sludge can easily cause localised blockages in pipes and nozzles, leading to flow deviation, dry walls and localised overheating, which in turn promotes the formation of carbonised scale layers.

Sludge entraining impurities exacerbates synergistic corrosion

Filter residue adsorbs acids, alkalis, sulphides and salts, and, adhering closely to the wall surface, continuously releases corrosive agents, causing long-term, gradual erosion of the base material.
