Corrosion is costly to your business

H2S resulting from submerged parts of structures in sewers or WWTPs gradually degrades the pipe until it collapses, causing public hazards, downtime of the sewer, reactive maintenance works, time losses, and increase in expenditure. The speed of corrosion will depend on the extent of the septicity and the effectiveness of any treatment against H2S in the network. Preventing H2S is a business gain, as it combats corrosion and avoids the collapse of pipes.

Yara can help you define how much Corrosion is costing your business, by the use of our tailored Corrosion Calculator.

How can Yara’s Corrosion Assessor help you determine the effects on your pipeline?

Create a Login which saves each of your Assessments for later discussions

  • Share your Assessments with colleagues (Is this function available?)
  • Once Logged in you will need to provide the following details:
    • System type, Surroundings, Road Access, Average H2S Levels (PPM), Year installed
    • Pipe name, Length (m), Daily flow (m3),Diameter (mm), Installed

What information can you expect from the Corrosion Calculator?

From this data, the Corrosion Assessor will determine:

  • the current H2S damage in your system
  • its remaining lifespan
  • options available of whether to repair or replace and at what cost
  • the time interval to perform the repairs or replacement. You will also know the new lifespan of your updated system.

You will also be able to compare these results with the those using a biological treatment to prevent the formation of H2S.

How corrosion happens

In the hot and humid atmosphere within a sewer, hydrogen sulphide (H2S) will be oxidised into sulphuric acid by Thiobacillus bacteria (Gram-negative), on the walls of the pipe. This sulphuric acid is corrosive and attacks the wastewater and sewage treatment infrastructure. Corrosion particularly affects the submerged parts of structures in sewers or WWTPs.

The H2S resulting from this condition gradually degrades the pipe until it collapses, causing public hazards, downtime of the sewer, reactive maintenance works, time losses, and increase in expenditure. The speed of corrosion will depend on the extent of the septicity and the effectiveness of any treatment against H2S in the network. Preventing H2S is a business gain, as it combats corrosion and avoids the collapse of pipes.
