Abstract: A Method for reliability strength designing pressure parts of boilers is presented. Based on existing strength calculation formulas for pressure parts of boilers and taking into consideration the scatter of the various design magnitudes, a way how the strength design reliability of pressure parts for boilers may be determined with the help of reliability analysis methods is showed. Techniques for determining the distribution parameters, as well as reliability calculation models are also described. Reliability design methods of tubes, pipes, round header, drum shells and ends are given together with some practical examples.
