Da sie nicht sichtbar ist, bleibt CUI h\u00e4ufig unentdeckt, bis bereits erhebliche Sch\u00e4den entstanden sind.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Wo tritt CUI auf?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CUI ist ein gro\u00dfes Problem in Branchen, in denen isolierte Anlagen wechselnden Temperaturen ausgesetzt sind:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>\u00d6l &amp; Gas <\/strong>\u2013 isolierte Rohrleitungen, W\u00e4rmetauscher und Prozessanlagen.<\/li>\n\n\n\n<li><strong>Petrochemie &amp; Chemie <\/strong>\u2013 Reaktoren und Beh\u00e4lter mit Heiz- und K\u00fchlzyklen.<\/li>\n\n\n\n<li><strong>Offshore &amp; Marine<\/strong> \u2013 isolierte Rohrleitungen und Tanks in feuchter, salzhaltiger Umgebung.<\/li>\n\n\n\n<li><strong>Stromerzeugung<\/strong> \u2013 Dampfleitungen, Turbinen und Kessel.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">F\u00fcr Sie als Anlagenbetreiber bedeutet CUI unerwartete Leckagen, eine verk\u00fcrzte Lebensdauer von Anlagen und kostspielige Stillstandszeiten, wenn das Problem nicht fr\u00fchzeitig erkannt wird.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Zus\u00e4tzliche Erkl\u00e4rung und Herausforderungen<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Ursache<\/strong>: eindringende Feuchtigkeit durch besch\u00e4digte Isolierung oder Verkleidung.<\/li>\n\n\n\n<li><strong>Risiken<\/strong>: beschleunigte Korrosion durch eingeschlossene Feuchtigkeit und fehlende Sichtbarkeit.<\/li>\n\n\n\n<li><strong>Erkennung<\/strong>: schwierig, da Inspektionen und die Entfernung der Isolierung erforderlich sind.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Traditionelle offene Strahlarbeiten zur CUI-Instandsetzung verursachen zus\u00e4tzliche Risiken wie Staub, R\u00fcckst\u00e4nde und Ger\u00fcstaufwand.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pinovos L\u00f6sung:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>PiPoint&#x2122;<\/strong> \u2013 erm\u00f6glicht gezieltes punktuelles Strahlen direkt an von CUI betroffenen Bereichen.<\/li>\n\n\n\n<li><strong>PiHab&#x2122;<\/strong> \u2013 flexible Einhausung f\u00fcr Seilzugangsarbeiten oder enge R\u00e4ume.<\/li>\n\n\n\n<li><strong>Dust-free
