Seminar 24 -- Proper Sizing of Copper Tube and Fittings for High Pressure Refrigerant Applications

This product is a PDF that contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

The purpose of the session is to address inconsistencies in current practices for predicting failure in pressure piping. This is particularly important to engineers using R410a and CO2 in their refrigeration designs. Presentations show hoop strain is a better predictor of failure than wall thickness for pressure piping; compare hoop strain predicted performance to other performance predictors; and lastly describe what changes to ASME and ASTM codes are under development with this knowledge.
