DEVELOPMENT OF DESIGN RULES FOR THREE-SEGMENT PIPE CLAMP CONNECTORS

摘要

The design rules for clamped connections in the ASME Boiler and Pressure Vessel Code (Section Ⅷ, Div. Ⅰ, Appendix 24) were developed for two-segment clamp connectors and must be modified to accommodate alternative clamp configurations. Developing a simplified rule-based model for predicting three-segment pipe clamp connectors (3-PCC)connector pressure capacities will greatly simplify the evaluation of 3-PCC connectors. The first goal of this paper is to develop a general parametric design rule set for multiple-clamp-segment pipe by expanding upon the published requirements of the ASME Boiler and Pressure Vessel Code for two-segment pipe clamp connectors and pipe flanges using basic principles. The next goal is to apply the design rule set to a typical 3-PCC design and to summarize the rules. The results of this paper provide a parametric rule-based approach to evaluating the pressure capacity of a 3-PCC. This paper has been developed in partial fulfillment of the requirements for the Master's Degree Program at Washington State University.
