Korrosion und spezifische Mängel an Stahltanks und Kunstofftanks

Bei der Korrosion von Stahltanks und den besonderen Herausforderungen von Kunststofftanks gibt es erhebliche Unterschiede, da beide Materialien unterschiedliche Reaktionen auf Umwelteinflüsse und Lagerbedingungen zeigen. Während Stahltanks hauptsächlich von elektrochemischer Korrosion betroffen sind, haben Kunststofftanks andere spezifische Probleme, die berücksichtigt werden müssen.

Korrosion und Probleme bei Stahltanks

Stahltanks sind aufgrund ihrer Materialeigenschaften und des häufigen Kontakts mit Wasser und Chemikalien besonders anfällig für Korrosion. Die Hauptprobleme und Schutzmaßnahmen sind:

Elektrochemische Korrosion:
Wie bereits erwähnt, ist die elektrochemische Korrosion bei Stahltanks das größte Problem, insbesondere wenn sie mit Wasser, Feuchtigkeit oder aggressiven Chemikalien in Berührung kommen. Rostbildung ist ein häufiges Problem, das die strukturelle Integrität gefährden kann.
Mikrobiell induzierte Korrosion (MIC):
Stahltanks sind anfällig für mikrobiell induzierte Korrosion, insbesondere in der Öl- und Gasindustrie oder bei Tanks, die organische Materialien oder Wasser lagern. Sulfatreduzierende Bakterien (SRB) sind besonders schädlich, da sie aggressive Stoffe wie Schwefelwasserstoff produzieren, der Korrosion fördert.
Beschichtungen und Kathodischer Schutz:
Die Verwendung von Schutzbeschichtungen (z.B. Epoxidharz oder Polyurethan) und kathodischem Schutz (Opferanoden) sind wichtige Maßnahmen, um die Lebensdauer von Stahltanks zu verlängern und Korrosion zu verhindern. Regelmäßige Wartung: Ohne regelmäßige Inspektionen und Wartung kann Korrosion unbemerkt fortschreiten und erhebliche Schäden verursachen.

Spezielle Probleme bei Kunststofftanks

Kunststofftanks (meist aus Polyethylen, Polypropylen oder glasfaserverstärktem Kunststoff) sind nicht anfällig für Korrosion im herkömmlichen Sinne, da sie nicht aus Metall bestehen. Allerdings haben Kunststofftanks andere spezifische Herausforderungen:

Chemische Zersetzung:
Kunststofftanks sind gegenüber bestimmten Chemikalien empfindlich, die die Struktur des Materials angreifen können. Einige aggressive Chemikalien oder Lösungsmittel können den Kunststoff schwächen oder ihn spröde machen, was zu Rissen oder Leckagen führt.
Stressrissbildung: Einige Chemikalien, insbesondere organische Lösungsmittel, können Spannungsrisse (Stress-Cracking) im Kunststoff verursachen. Diese Risse können sich mit der Zeit ausbreiten und schließlich zu Undichtigkeiten führen.
UV-Degradation:
Kunststofftanks, die im Freien stehen, sind der UV-Strahlung der Sonne ausgesetzt. Langfristige Exposition gegenüber UV-Strahlen kann das Material abbauen und es spröde machen. Dieser Prozess wird als UV-Degradation bezeichnet und kann die Haltbarkeit der Tanks erheblich reduzieren.
Lösungen: Um dieses Problem zu vermeiden, werden Kunststofftanks oft mit UV-Stabilisatoren behandelt oder durch Farbanstriche or Abdeckungen geschützt.
Temperaturbeständigkeit:
Kunststofftanks sind empfindlicher gegenüber extremen Temperaturen als Stahltanks. Bei hohen Temperaturen kann sich der Kunststoff verformen oder weicher werden, was die strukturelle Integrität gefährdet. Bei sehr niedrigen Temperaturen kann Kunststoff spröde und anfällig für Risse werden.
Mechanische Schäden:
Während Stahltanks mechanische Belastungen relativ gut aushalten können, sind Kunststofftanks anfälliger für mechanische Beschädigungen. Kratzer oder Schläge können zu Rissen oder Leckagen führen, insbesondere bei Tanks, die stark belastet oder im Freien aufgestellt werden.
Diffusion:
Ein weiteres Problem bei Kunststofftanks ist die Permeabilität. Einige Chemikalien können durch den Kunststoff diffundieren, was zu einem allmählichen Verlust des Inhalts oder einer Verunreinigung der Umgebung führen kann. Dies ist insbesondere bei der Lagerung von brennbaren Flüssigkeiten or Lösungsmitteln relevant.
Langzeitbelastung:
Kunststofftanks unterliegen auch der sogenannten Kriechverformung. Das bedeutet, dass das Material unter anhaltender Belastung (z.B. durch das Gewicht des Inhalts) allmählich seine Form verändern kann. Dies kann zu einer strukturellen Schwächung des Tanks führen, besonders bei großen oder hochgefüllten Tanks.

Vergleich zwischen Stahl- und Kunststofftanks

Aspekt	Stahltanks	Kunststofftanks
Korrosionsanfälligkeit	Hohe Korrosionsgefahr, besonders bei Wasser und Chemikalien	Keine Korrosion im herkömmlichen Sinne, aber chemische Angriffe möglich
Schutzmaßnahmen	Schutzbeschichtungen, kathodischer Schutz, regelmäßige Inspektionen	UV-Stabilisatoren, Chemikalienbeständigkeit, mechanische Schutzmaßnahmen
Chemische Beständigkeit	Abhängig von der Beschichtung, kann durch aggressive Chemikalien angegriffen werden	Gute Beständigkeit gegenüber vielen Chemikalien, aber bestimmte Substanzen können Spannungsrisse verursachen
Mechanische Stabilität	Sehr hoch, widerstandsfähig gegen mechanische Belastungen	Empfindlich gegenüber Kratzern, Stößen und mechanischen Beschädigungen
Wartung	Regelmäßige Inspektion und Wartung erforderlich, um Korrosion zu vermeiden	Weniger Wartung erforderlich, aber regelmäßige Überprüfung auf UV-Schäden und Risse

Sowohl Stahl- als auch Kunststofftanks haben spezifische Herausforderungen, die bei ihrer Nutzung berücksichtigt werden müssen. Während Stahltanks anfällig für elektrochemische Korrosion und mikrobiell induzierte Korrosion sind, haben Kunststofftanks Probleme wie chemische Zersetzung, UV-Degradation und mechanische Schwächen. Beide Tanktypen erfordern spezifische Schutzmaßnahmen, um ihre Lebensdauer zu verlängern und ihre Funktionalität zu gewährleisten.

The Flyability ELIOS 3 drone enables safe inspections of confined, hard-to-reach and potentially hazardous areas without employees having to take risks. It is controlled from the ground or outside the structures and delivers high-resolution images and precise data. Its robust design and ability to navigate safely in low light and confined environments minimises the risk of accidents. This method is ideal for inspecting tanks and silos that are pressurised, chemically contaminated or difficult to access, providing an efficient and thorough solution without putting personnel at risk.

How long does it take to inspect tanks and silos with the Flyability ELIOS 3 drone?

The duration of an inspection of tanks and silos with the Flyability ELIOS 3 drone depends on the size, condition and complexity of the structures to be inspected. In general, a drone inspection is significantly faster than conventional methods as no scaffolding, working platforms or rope access techniques are required. Smaller tanks or simple silo structures can often be fully inspected within a few hours. For larger tanks, complex systems or when several tanks and silos are inspected at once, the inspection can take a whole day or longer. However, with efficient data collection and documentation, inspection times can be significantly reduced compared to traditional methods, minimising downtime and optimising operations.

How are the targets for the drone inspection of tanks and silos defined and controlled?

The objectives for the drone inspection of tanks and silos are defined in advance in close consultation with the customer. The first step is to clarify why the inspection is being carried out - whether it is for a routine check, to document damage or to comply with legal requirements. We also discuss whether testing organisations or external experts are involved and what specific requirements they have for the inspection. Based on this information, we plan the inspection specifically according to the customer's needs. During the inspection, we ensure that all relevant areas are thoroughly checked and that the data collected corresponds to the defined objectives. In this way, we ensure a customised inspection solution that meets the highest standards and delivers precise results.

Training includes understanding flight safety, operating the drone in confined and difficult spaces and analysing the data collected. With the right training, the ELIOS 3 drone can be optimally utilised to carry out safe and efficient inspections.

What happens if defects or damage are discovered during the inspection of tanks and silos?

If defects or damage are detected during the inspection of tanks and silos, these anomalies are immediately reported to the customer. Our drones capture high-resolution images and precise data that make it possible to directly assess the nature and extent of the damage. The information gathered is documented in a detailed report and discussed with the customer so that quick and targeted action can be taken to rectify the problems identified. This proactive communication helps to minimise potential risks and ensure a rapid response to detected defects.

Can the drone inspection of tanks and silos also be carried out during ongoing operations?

The drone inspection of tanks and silos cannot usually be carried out during ongoing operations. The respective tanks or silos must be taken out of operation, emptied and cleaned to enable a safe and effective inspection. This is the only way to reliably identify and document defects such as cracks, corrosion or deposits. Preparation and decommissioning of the plant are necessary to operate the drone safely and ensure precise inspection results.
