Dynamics of pig motion in gas pipelines
WebMar 1, 2016 · Most pigging operations in gas pipelines are performed at normal operating pressures with regular flow rates, and the PIG velocity is generally in the range of 2–5 m/s. However, pigging in low-pressure and low-flowrate gas pipelines is very difficult due to speed excursion, which rapidly increases the PIG velocity. WebAug 25, 2024 · Various intelligent pipeline inspection gauges (PIGs) are required to perform dehydration, cleaning, and interior inspection operations to improve these efficiency and safety of pipelines. 1 Periodic cleaning of oil and gas pipelines using cleaning PIGs is the most suitable and efficient solution and has become the industrial standard procedure ...
