Webinar outline
Beneath the surface: Stainless steel underground
Stainless steel delivers exceptional long-term performance underground, transporting fuels, water, and waste across a wide range of environments. Stronger than polymers and copper, and more resistant to chlorides and acidic soils than lead or galvanised steel, it offers a durable and sustainable solution for buried infrastructure.
This webinar explores how stainless steel performs beneath the surface, from oil characteristics and corrosion mechanisms to standards, test methods, and long-term exposure results. Gain insights into the key factors influencing underground durability and how stainless steel compares with alternative materials.
Key takeaways:
- Real-world applications of stainless steel in underground environments
- How underground exposure differs from atmospheric or immersed service
- Understanding soil characterisation and corrosivity
- Differences between buried pipes and driven piles and their installation impacts
- Critical parameters and standards used to assess metallic durability
- The impact of stray electrical currents and faulty building earths on underground corrosion
- Recommended limits for stainless steels and the relevance of PRE values
- Results from long-term exposure studies of buried stainless steels
- Comparison of stainless steel, copper, polymers, and coated steel in potable water service
Attendees are encouraged to submit specific cases in advance or bring them up during the Q&A session (
