Question

Some of the standards for components in ASME B31.3, table 326.1 (e.g. ASME B16.9, B16.11, and B16.28) state that pressure-temperature ratings are based on straight seamless pipe. Except as limited in the standard or elsewhere in B31.3, such a component, made of a material having the same allowable stress as the pipe shall be rated using not more than ____ % of the nominal thickness of the seamless pipe corresponding to the schedule! weight! or pressure class of the fitting! less all allowances applied to the pipe.

Answer 1

Pressure-temperature ratings for components in ASME B31.3 standards are based on the nominal thickness of seamless pipe. The percentage of the nominal thickness that can be used depends on the schedule, weight, or pressure class of the fitting. This ensures the safe operation of the components.

Step-by-step explanation:

The question is asking about the pressure-temperature ratings for components in ASME B31.3 standards, specifically those mentioned in table 326.1. According to these standards, components made of a material with the same allowable stress as the pipe should be rated using not more than a certain percentage of the nominal thickness of the seamless pipe corresponding to the schedule, weight, or pressure class of the fitting, less all allowances applied to the pipe. This is important for ensuring the safe and reliable operation of the components in various applications.
