Impact Test Requirements as per ASME Section VIII Division

Carbon steel and low alloy steels show a drastic change in room temperature ductility at sub-zero temperatures.This behavior is different for different types of materials.Therefore,impact testing at such service temperatures is mandatory to ensure the strength of vessel material.ASME provides some exemption for impact testing of materials in code.Unless exempted Continue reading Interpretation VIII-1-01-08 - Note these interpretations Question (1) An MAWP and MDMT of a vessel are initially established using the rules of Section VIII,Division 1,Subsequently the rules of UCS-66(b)(1) are used to establish a second MDMT that is colder than the initial MDMT at a coincident MAWP that is lower than the initial MAWP.Based on footnote 37 in UG-116,may both the initial and MDMT of 304 SS - ASME (mechanical) Code Issues - Eng-TipsJan 28,2011·Hey Everyone Per ASME DIv.1,what is the MDMT of SA-24-304 stainless steel,assuming no hardness testing?

Materials - Corrosion and Corrosion Allowance

As far as I know,there is no corrosion allowance exactly specified in ASME B31.3.Corrosion allowances are normally established by the end user and are somewhat based on personal preferences and industry tradition.1.5 mm for piping is a common standard,but you are free to set a corrosion allowances you wish,unless a state or local agency Maximum Allowable Stress - an overview ScienceDirectMaurice Stewart,in Gas-Liquid And Liquid-Liquid Separators,2008.5.2.3 Maximum Allowable Stress Values.The maximum allowable stress values to be used in the calculation of a vessel's wall thickness are given in the ASME code for many different materials.These stress values are a function of temperature.Section VIII of the ASME code,which governs the design and construction of all NORSOK STANDARDMINOR DEVIATIONS FROM ASME B31.1 CODE REQUIREMENTS The use of the piping materials according to NORSOK Standards (L-CR-001,M-630 and M-601) will result in some minor deviations from the ASME B31.3 code.All deviations have been carefully considered,and they are in line with Norwegian and European practice.The deviations are:
