Key Specifications / Features
Killed Carbon Steel Gate Valves are mostly used in vessels, heat exchangers, oil and gas pipelines, and underground pipelines.
Killed Carbon Steel are defined as those which are thoroughly deoxidized during melting process. Deoxidation is accomplished by use of silicon, manganeese and aluminium additions to combine with dissolved gases, usually oxygen, during steel making. This results in cleaner, better qualtity steel which has fewer gas pockets and inclusions. Killed carbon steel is specified for major equipment in the following services to minimise the possibility or extent of hydrogen blistering and hydrogen embrittlement:
- where hydrogen is a major component in the process stream.
- where hydrogen sulphi..
