Abstract

Abstract: The stress calculation method used in the international standards for plastic pressure piping systems for hot and cold water installation was introduced. Based on the calculation of the design stress for hot and cold water installation, the broken contribution probability for different materials was compared. The calculation examples showed that the formula used in the international standard were questionable. Further study in this field was necessary.
