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.
