This paper consists of a literature review on the latest research progress about lateral buckling submarine pipelines under high temperature (HT) and pressure (HP). First, main general assumptions simplifications made in context pipe are summarized order to better understand practical behavior pipelines. The governing equations uniaxial compression then derived. Next, controversial but widely d...

High-temperature pressure pipelines are extensively used in petrochemical plant and power stations. Severe pits or wall loss defects can be internally produced after a certain period of time due to media corrosion and cavitation erosion. These defects finally lead to leakage of the pipes. In order to search for a good non-destructive method for these defects, a large pipe testing installation w...

A CGS is of the most important parts in natural gas transmission pipelines in which the high inlet natural gas (NG) pressure is reduced to much lower value by employing a throttling valve. This pressure drop causes hydrate forming, preventing stable NG flow through the pipeline. To prevent hydrate forming, NG is usually preheated by heaters which burns remarkable amount of NG. In this work, a n...
