Happy New Year, everyone!

The challenge of handling fluids containing significant amounts of hydrogen sulfide (H₂S) has led me to explore the suitability of H₂S-resistant fiberglass composite pipes. These pipes need to meet stringent requirements to ensure they perform reliably in such harsh environments.

From my literature review, it appears that epoxy, commonly used as the primary matrix material in fiberglass composites, exhibits inertness to H₂S-provided it is fully cured. However, I'm curious to know whether all epoxy grades share this resistance or if some are better suited for H₂S exposure than others. Additionally, I wonder if upgrading to more specialized or expensive resin systems might be necessary to enhance the pipe's resistance.

I'd greatly appreciate your thoughts, experiences, or advice on this topic. Are there specific epoxy grades or alternative resins you'd recommend for applications with high H₂S exposure?

Looking forward to your valuable insights!

Thank you!

Hello Lei Zhao,

What may proof to give you ready some interesting information concerning the degradation of epoxy, and the combination met hydrogen sulphide, can be found in: "Corrosion Resistance Tables: Metals, Nonmetals, Coatings, Mortars, Plastics, Elastomers, and Linings and Fabrics, Fifth Edition (4 Volume Set) (Corrosion Technology) by Philip A. Schweitzer P.E. (Editor)"

In this book 7 different types of epoxies are evaluated in 4 different hydrogen sulphide based environments.

Best Regards,

Johan
