The ductile fracture arrest may present supplementary requirement for selection of base material for most demanding steel welded structures. The most representative one with such requirement are gas pipelines. Therefore to ensure that the pipeline materials has adequate toughness to arrest a ductile fracture, the pipe material must be designed and tested in accordance with the specific procedur...

The paper shows a comparison between two intervention methods for interconnecting gas transmission pipelines within natural system. One implies shutdown of pipelines, while the other one in-service pipelines. Each method is described in detail along with main technological issues, as well related advantages and disadvantages. procedures imply special working techniques such welding or hot tappi...

OBJECTIVE Known as an uncommon disease at the beginning of the 20(th) century, lung cancer has been the most frequent cause of cancer-related deaths in males since the 1950s and in females in the last two decades. The aim of this study was to determine the lung cancer incidence in Erzurum; its clinical properties, cancer subtypes, and application phases; the relationships of tumors with paramet...

Background Renewable Natural Gas (RNG) is pipeline quality gas that is fully interchangeable with fossil natural gas but is produced from a renewable feedstock and can be used as a 100% substitute for, or blended with, conventional natural gas streams [1]. RNG is an important alternative fuel that can help the State of California meet several GHG and renewable energy targets. As a transportatio...

A leaking water pipe bursting high pressure water jet in the soil will create slurry erosion which will eventually erode the adjacent natural gas pipe, thus causing its failure. The standard 300 mm safety distance used to place natural gas pipe away from water pipeline facilities needs to be reviewed to consider accidental damage and provide safety cushion to the natural gas pipe. This paper pr...

In engineering design, material selection is the process of choosing best for a specific via systematic approach. This article described SBR#2 pipeline, which will be installed to flow raw gas from field nearest tie-in point. The starts with design requirement analysis generate primary function and objectives, including its constraints, determine criteria evaluated, screen materials candidates ...

Statoil has designed and tested dual diameter pipeline pigs to perform various tasks during operations, precommissioning and commissioning of the 710km 42"x28" Åsgard pipeline. The concepts developed have been put through a major design and testing program to demonstrate that the various functional requirements have been met. The paper describes the development process as well as field experien...
