Examples of Sulfide stress cracking in a sentence

  • Sulfide stress cracking (SSC) is observed when a material is exposed to the combined action of mechanical tensile stress and corrosion in the presence of aqueous hydrogen sulfide, H2S.

  • Sulfide stress cracking (SSC) is one of the main risks of steel failures in H2S environments.

  • API Std 526 Flanged Steel Safety Relief Valves.EN 10204 Metallic Products – Types of inspection documents.NACE MR 0175 Sulfide stress cracking resistant metallic materials for oil field equipment.

  • Sulfide stress cracking is a phenomenon where susceptible materials may fail due to a complex interaction of metal composition, hardness, heat treatment, microstructure, and other factors such as pH, hydrogen sulfide concentration, stress, and temperature.

  • Sulfide stress cracking can occur in environments containing an aqueous phase and hydrogen sulfide (H2S), environmental cracking can occur in some materials, particularly hardened steels.

  • Sulfide stress cracking decreases in severity with incre- ased temperature.Other types of corrosion include: galvanic corrosion, corrosion fatigue and exfoliation, which involves the formation of layers of corrosion products, but these are less important in geothermal system.Compared to clogging, corrosion is less of a problem for wells and open loop system.
