Data analysis underpins successful pig rescue on small-diameter pipeline

2018-10-09 | By: Pooya Gholami

 The ability to pig a pipeline is crucial to maintenance and other operations such as pre-commissioning on the pipeline. Usually, high-length low-diameter pipelines are difficult to pig, and therefore produce a complicated pigging operation. There are several parameters that cause the pig(s) to get stuck. These include cleanliness of the pipeline; an accumulated amount of debris and corrosion product; pipeline dents or buckles; and erosion of pig disks. Recently, a pigging operation was performed in a…
