Corrosion and specific defects in steel tanks and plastic tanks

With the Corrosion of steel tanks and the special challenges of plastic tanks There are considerable differences between the two materials, as they react differently to environmental influences and storage conditions. While steel tanks are mainly affected by electrochemical corrosion, plastic tanks have other specific problems that need to be taken into account.

Corrosion and problems with steel tanks

Steel tanks are particularly susceptible to corrosion due to their material properties and frequent contact with water and chemicals. The main problems and protective measures are

Electrochemical corrosion:
As mentioned above, electrochemical corrosion is the biggest problem with steel tanks, especially when they come into contact with water, moisture or aggressive chemicals. Rust formation is a common problem that can jeopardise structural integrity.
Microbially induced corrosion (MIC):
Steel tanks are susceptible to microbially induced corrosion, especially in the oil and gas industry or in tanks that store organic materials or water. Sulphate-reducing bacteria (SRB) are particularly harmful as they produce aggressive substances such as hydrogen sulphide, which promotes corrosion.
Coatings and cathodic protection:
The use of protective coatings (e.g. epoxy resin or polyurethane) and cathodic protection (sacrificial anodes) are important measures to extend the service life of steel tanks and prevent corrosion. Regular maintenanceWithout regular inspections and maintenance, corrosion can progress unnoticed and cause considerable damage.

Special problems with plastic tanks

Plastic tanks (usually made of polyethylene, polypropylene or glass fibre reinforced plastic) are not susceptible to corrosion in the conventional sense, as they are not made of metal. However, plastic tanks have other specific challenges:

Chemical decomposition:
Plastic tanks are more favourable than certain chemicals which can attack the structure of the material. Some aggressive chemicals or solvents can weaken the plastic or make it brittle, leading to cracks or leaks.
Stress crackingSome chemicals, especially organic solvents, can cause stress cracking in the plastic. These cracks can spread over time and eventually lead to leaks.
UV degradation:
Plastic tanks that are located outdoors are the UV radiation exposed to the sun. Long-term exposure to UV rays can degrade the material and make it brittle. This process is known as UV degradation and can significantly reduce the durability of the tanks.
Solutions: In order to avoid this problem, plastic tanks are often UV stabilisers treated or by Colour coatings or Covers protected.
Temperature resistance:
Plastic tanks are more sensitive to extreme temperatures than steel tanks. At high temperatures, the plastic can deform or soften, jeopardising the structural integrity. At very low temperatures, plastic can become brittle and susceptible to cracking.
Mechanical damage:
While steel tanks can withstand mechanical stress relatively well, plastic tanks are more susceptible to Mechanical damage. Scratches or knocks can lead to cracks or leaks, especially in tanks that are subject to heavy loads or are installed outdoors.
Diffusion:
Another problem with plastic tanks is the Permeability. Some chemicals can diffuse through the plastic, which can lead to a gradual loss of the contents or contamination of the environment. This is particularly important when storing flammable liquids or Solvents relevant.
Long-term exposure:
Plastic tanks are also subject to the so-called Creep deformation. This means that the material can gradually change its shape under continuous load (e.g. due to the weight of the contents). This can lead to a structural weakening of the tank, especially in the case of large or highly filled tanks.

Comparison between steel and plastic tanks

Aspect	Steel tanks	Plastic tanks
Susceptibility to corrosion	High risk of corrosion, especially with water and chemicals	No corrosion in the conventional sense, but chemical attacks possible
Protective measures	Protective coatings, cathodic protection, regular inspections	UV stabilisers, chemical resistance, mechanical protection measures
Chemical resistance	Depending on the coating, can be attacked by aggressive chemicals	Good resistance to many chemicals, but certain substances can cause stress cracks
Mechanical stability	Very high, resistant to mechanical loads	Sensitive to scratches, impacts and mechanical damage
Maintenance	Regular inspection and maintenance required to prevent corrosion	Less maintenance required, but regular checks for UV damage and cracks

Both Steel as well as Plastic tanks have specific challenges that must be taken into account when using them. While steel tanks are susceptible to Electrochemical corrosion and Microbially induced corrosion plastic tanks have problems such as chemical degradation, UV degradation and mechanical weaknesses. Both tank types require specific protective measures to extend their service life and ensure their functionality.

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.
