Corrosion concentrates where the fluid stagnates, where turbulence is greater or where the internal lining has failed: the bottom, the areas near the nozzles, the interface line between the liquid and the vapour phase. The average value is of no use; what counts is the thinnest point.  <\/p>\n\n<p class=\"wp-block-paragraph\">That is why the inspection is organised as a mapping, not as an isolated reading. A grid of uniquely identified points is defined, it is followed again at every inspection and the values are compared with those of the previous campaigns. The difference between two campaigns, divided by the time elapsed, is the corrosion rate on which the calculated remaining life depends.  <\/p>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-cover is-light popmake-4066 popmake-739\" style=\"border-width:1px;min-height:250px;aspect-ratio:unset;\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"250\" class=\"wp-block-cover__image-background wp-image-727 size-full\" alt=\"\" src=\"https:\/\/i0.wp.com\/ultrasuonindt.it\/wp-content\/uploads\/2026\/04\/banner_technical_support_choose_products.png?resize=1200%2C250&#038;ssl=1\" data-object-fit=\"cover\" srcset=\"https:\/\/i0.wp.com\/ultrasuonindt.it\/wp-content\/uploads\/2026\/04\/banner_technical_support_choose_products.png?w=1200&amp;ssl=1 1200w, https:\/\/i0.wp.com\/ultrasuonindt.it\/wp-content\/uploads\/2026\/04\/banner_technical_support_choose_products.png?resize=300%2C63&amp;ssl=1 300w, https:\/\/i0.wp.com\/ultrasuonindt.it\/wp-content\/uploads\/2026\/04\/banner_technical_support_choose_products.png?resize=1024%2C213&amp;ssl=1 1024w, https:\/\/i0.wp.com\/ultrasuonindt.it\/wp-content\/uploads\/2026\/04\/banner_technical_support_choose_products.png?resize=768%2C160&amp;ssl=1 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim-30 has-background-dim\" style=\"background-color:#d3d6dc\"><\/span><div class=\"wp-block-cover__inner-container is-layout-constrained wp-container-core-cover-is-layout-15701bb7 wp-block-cover-is-layout-constrained\">\n<p class=\"has-text-align-right has-ti-fg-color is-style-default has-luminous-vivid-amber-color has-text-color has-link-color wp-elements-1 wp-block-paragraph\" style=\"font-size:clamp(21.536px, 1.346rem + ((1vw - 3.2px) * 1.374), 35px);\"><strong>Need help choosing the right product?<\/strong><\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-right is-layout-flex wp-container-core-buttons-is-layout-b507c051 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button popmake-4066 popmake-739\"><a class=\"wp-block-button__link has-ti-accent-color has-cyan-bluish-gray-background-color has-text-color has-background has-link-color wp-element-button\">Contact us<\/a><\/div>\n<\/div>\n<\/div><\/div>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<p class=\"wp-block-paragraph\">Echo-Echo mode makes it possible to take the measurement without removing the surface insulation or the protective paint: the instrument ignores the coating layer and returns the thickness of the metal alone.
