Until a few years ago there had been no record of stress corrosion cracking (SCC) as a main cause of failures in Argentine pipelines, but as the pipeline system became of a certain age this mechanism started to have an ...

Based on fractographic, metallurgical, mechanical and fracture mechanics analyses, the causes of three failures in welded full encirclement sleeve repairs in a 24 in gas pipeline were evaluated. These failures were related ...

A succinct description of the particular conditions that have led to failures and damage of buried pipelines in Argentina is given in this article. The particular characteristics of soil, demographic evolution, original ...

Conventional procedures used to assess the integrity of corroded piping systems with axial defects generally employ simplified failure criteria based upon a plastic collapse failure mechanism incorporating the tensile ...

The purpose of this research is to predict failures (corrosion, cracks, laminations, joins or others) in pipelines carrying natural gas. Using the Bees Algorithm based on the behavior that is performed in nature. The ...

In pipelines, one of the primary testing procedures used to identify the effects and evolution of corrosion over time is through In-Line Inspections (ILI). ILI inspections provide detailed information regarding the inner ...

An uncommon blow out in a 24″ diameter, 7 mm thick API 5L X52 gas pipeline was due to fracture at the longitudinal double submerged arc weld (DSAW). Fatigue cracks were found to have initiated from a large embedded weld ...

This article concerns the loss of a Horizontal Directional Drilling crossing due to a failure that took place during pullback of the pipeline. The more than 500 m long drilling was meant to lodge a 30″ pipeline that crossed ...
