Abstract This paper will present an eye-opening look at some of the historic data and letters of correspondence that are the historical basis of the API RP and Petrochemical Plants. API RECOMMENDED PRACTICE API publications necessarily address problems of a general nature. With respect to particular. practice (RP) , “Steels for Hydrogen Service at Elevated Temperatures and Pressures in temperature and pressures should follow API RP guideline.

In addition, it includes a summary of inspection methods to evaluate equipment for the existence of HTHA. API Supplement 1. This week, we’d like to provide the reader with a few helpful resources that deal with the topic of HTHA.
A summary api rp 941 inspection methods to evaluate equipment for the presence of HTHA is also included. This recommended practice summarizes the results of experimental tests and actual data acquired from operating plants to establish practical operating limits for carbon and low alloy steels in hydrogen service at elevated temperatures and pressures.
The benefits of a subscription: Asset Intelligence Reports Download brief primers on various asset integrity management topics. However, they may not be resistant to other corrosives present in a process stream or to other metallurgical damage mechanisms that can occur in the api rp 941 HTHA range. Though HTHA failures in these units are the focus of api rp 941 article, it is important to recognize that HTHA damage can also occur in high pressure boiler tubes, hydrogen producing units, synthetic gas units, ammonia plants and other equipment where hydrocarbons may not be involved but high temperatures are involved.
American Petroleum Institute Dates: This standard is available for individual purchase.
This Standard References Showing 10 of The guidelines in this recommended practice can also be applied to hydrogenation plants such as those that manufacture ammonia, methanol, edible oils, and higher alcohols.
Start Webshop Product catalog Product presentation. Likewise, this RP only applies to HTHA thus, even when ep the guidelines listed in this RP, api rp 941 might not necessarily resist other damage mechanisms in a process stream.

High Temperature Hydrogen Attack HTHA is a long known and still occurring degradation issue for fixed equipment construction materials in the hydrocarbon process industry where hydroprocess plants ep plus hydrocarbons are in service. Acronyms Commonly used asset integrity management and inspection acronyms.
Last week we mentioned three important tips to consider when addressing high temperature hydrogen attack HTHA. At temperatures and hydrogen partial pressures below the curve, HTHA is not expected api rp 941 occur in carbon steel.
Api rp 941 those temperatures, hydrogen enters the steel due an electrochemical mechanism, which operates under different api rp 941. The API RP Task Group of the API Subcommittee on Corrosion and Materials is now in the early stages of collecting and verifying api rp 941 and information to determine if the recommended practice might need to be altered as a result of this new information.

API RP applies to any equipment in refineries, petrochemical facilities, chemical facilities, or hydrogenation plants that happen to operate in environments in which hydrogen-containing fluids are processed at elevated temperatures and pressures. NOK 2 ,00 excl. This ensures that you are always up-to-date api rp 941 saves you both time and money.
Monitoring Standards monitoring is a free api rp 941 designed for you who wish to be alerted of changes to or new editions of the standards required in your work.
This RP also does not api rp 941 the issues surrounding possible damage from rapid cooling of the metal after it has been in high temperature, high pressure hydrogen service e.
The api rp 941 on the resistance of steels api rp 941 hydrogen at elevated temperature and pressure that result from high stress, heat treating, chemical composition, and cladding are discussed. The agreement lasts for three years, and the fee is charged once per year. This RP applies to equipment in refineries, petrochemical facilities, and chemical facilities in which hydrogen or hydrogen-containing fluids are processed at elevated temperature and pressure.
