Underground pipe stress analysis considerations
Stress Analysis Methods for Underground Pipelines - Pipelines, Piping and Fluid Mechanics
Stress analysis of underground piping system is very complex and involves many other factors that are not involved in plant piping. Learn more about the key factors here.
Several failures in buried piping and pipeline systems over the years forced EPC companies to investigate stresses the system is experiencing. So, in recent times, stress analysis of underground piping and pipeline systems are made compulsory. In most of the cases, buried analysis is followed for pipelines as the maximum part of pipeline systems are underground. And the analysis is governed by ASME B31.4 or B 31.8 Codes.
The governing code for the pipe stress analysis is generally ASME B31.3[1] and 31.
