asme code list  the asme code list contains specific standards for the design, manufacture, installation, servicing, inspection, testing, and qualification of mechanical equipment and components. each standard is identified by a unique asme code. asme standards have been adopted by the asme board on standards and testing and the asme board on standards and technical development. asme's code list is available in a variety of online formats including: pdf, xml, csv, txt, html, rtf, odt, and ms word.


the asme mechanical code provides a set of standards that cover the design, construction, material selection, installation, inspection, maintenance, and testing of all mechanical systems. adopted by the asme board on standards and technical development in february 1993, asme mechanical code represents the highest level of current engineering knowledge. asme mechanical code was developed to improve the safety, reliability, serviceability, and overall quality of mechanical systems.


the asme ptc is a comprehensive document that establishes the methods and procedures to be used in testing, operating, and maintaining asme pressure vessels, the most significant of which are boiler units. the purpose of asme ptc is to address the testing, operating, and maintaining of pressure vessels in the following areas: pressure vessel inspection and testing; pressure vessel operating procedures; pressure vessel maintenance; and general procedures.


one of the major uses of the asme ptc's is to control heat transfer between the evaporator section of a nuclear reactor and the drywell section. one such use is to determine if condensation of steam is occurring in the drywell. this is done by installing an infrared heat flux sensor on the inner surface of the drywell. the flux sensor is designed to measure the temperature of the drywell. this sensor provides a signal when the temperature difference between the hot drywell surface and the cool wetwell surface exceeds a certain value. this value will be referred to as the "critical value". if the temperature difference is less than the critical value, the sensor will not provide a signal. 84d34552a1
