Carbon Steel Degradation in High Temperature Hydrogen Service The purpose of this alert is to inform you that there have been several reports of cracking -related issues with carbon steel piping and equipment in high temperature, high pressure hydroprocessing service at operating conditions where carbon steel was previously thought to be resistant to high temperature hydrogen attack Api rp 941.

Though HTHA failures in these units are the focus of this article, it is important to recognize api rp 941 HTHA damage can also occur in high pressure boiler tubes, hydrogen producing units, synthetic gas units, ammonia plants and other api rp 941 where hydrocarbons may not be involved but high temperatures are involved.

All of the new reports of HTHA involve carbon steel equipment that was not postweld heat treated. Speed up research, capture and reuse expertise For additional product information, visit the IHS Standards Expert page.

This week, api rp 941 like to provide the reader with a few helpful resources that deal with the topic of HTHA. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. Presented in ali document are curves that indicate the operating limits of temperature and hydrogen partial pressure for satisfactory resistance of carbon steel and Cr-Mo steels to HTHA in elevated temperature hydrogen service.

This standard is available for individual purchase. This RP api rp 941 to equipment in refineries, petrochemical facilities, and chemical facilities in which hydrogen or hydrogen-containing fluids are processed at elevated temperature and pressure.
