In addition, some suggestions for modeling strategies have been presented and discussed. Wear Pipeline Slurry Abrasion...

... rate of 0.36 mm/yr. Abstract A 2018 field investigation on an NPS 6, approximately 4 km long, liquid pipeline, identified a rectifier as the likely source of the elevated DC and AC current densities, which resulted in AC corrosion anomalies detected during in-line inspections (ILI). The findings...

...Abstract Newly constructed long-distance pipelines are often hydrotested with water from a natural reservoir without the use of chemical treatment. Chemicals are typically not used for various reasons: (i) the water is usually released back into the natural environment after use, (ii...

...Abstract According to a survey of corrosion releases in hazardous liquids pipelines, of the 52 internal corrosion releases reported in 2009-2012, 31 occurred in intermittently operated lines. Pigging operations cannot be performed in many of these pipelines for a number of reasons...

... ). It is based on multiple systems (MAPS-H ^† and MAPS-V ^† ) that generate fluid batches ² (finite, predetermined fluid volumes) in the flowlines or gathering pipelines and an AI-powered controller that determines launch times of the fluid batches at the MAPS units...

...Abstract CO₂ stream in CCS system usually contains impurities, such as water, O₂, SO₂, NO₂, H₂S, and other trace substances, which could pose a threat to internal corrosion and integrity of CO₂ transportation pipelines. The general...

...BACKGROUND Project Description The project NPS 6 pipeline is a 168.3 mm diameter, 3.95 km long pipeline which transports Liquid Petroleum Gas (LPG) from the terminal at the east end to a manifold at the west end of the line. This pipeline is externally coated with polyethylene (Yellow Jacket...

... potential surveys were applied to electrically continuous pipelines. Most water/wastewater pipeline designs utilize rubber gasket bell-and-spigot joints. Unless electrical continuity is intentionally designed for the pipeline such joints result in a pipeline with no electrical continuity. This paper...

Seamless Flux Cored wires for pipeline applications follow a different manufacturing approach compared to the conventional folded techniques and are much reliable with consistent performance in terms of weldability and quality. The seamless FCAW...

This is to ensure the success of internal girth weld coating by avoiding sharp-edges that can create holidays, thereby FBE coating failures. For pipeline applications with internal girth weld coating, GTAW process...
