Calculation formulas and description for dimensioning pre-insulated piping : Investigating the potential utilization of pre-insulated pipe calculation methods in LNG applications

Abstract

As the demand for liquefied natural gas increases globally there are many local emerging markets arising but the technology and the infrastructure is capital intensive. The plants include many piping solutions which need to be designed specifically for this kind of application. The objective of this work is to evaluate the potential of using a pre – insulated pipe dimensioning model, developed for Uponor Infra Oy, a market leading Finnish company in piping infrastructure manufacturing, for liquefied natural gas applications. The methods used during the study were research and mathematics based including researching European standards on pre – insulated piping and thermodynamic calculations to establish the method of calculating thermodynamic properties of pre – insulated pipes. The results indicate that there is a potential in using pre – insulated pipe dimensioning calculation methods for liquefied natural gas applications.
