In pipeline transportation, pigging is the practice of using pipeline inspection gauges or gadgets, devices generally referred to as pigs or scrapers, to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline.
Robotic non-destructive testing (NDT) is a method of inspection used to assess the structural integrity of petroleum, natural gas, and water installations. Crawler-based robotic tools are commonly used for in-line inspection (ILI) applications in pipelines that cannot be inspected using traditional intelligent pigging tools (or unpiggable pipelines).
An MFL tool is known as an "intelligent" or "smart" inspection pig because it contains electronics and collects data real-time while traveling through the pipeline. Sophisticated electronics on board allow this tool to accurately detect anomalies as small as 1 mm 2 , which can include dimensions of a pipeline wall as well as its depth and ...
Hydraulically activated pipeline pigging (HAPP) is a pigging technology applied for pipeline cleaning. The basic principle is that a pressure drop is created over a by-passable pig held back against a pipeline's fluid flow. The pipeline fluid passing through the pig's cleaning head is accelerated by this pressure drop, forming strong cleaning jets.
Video scoping of pipes and high tech smart pigs are used for internal inspections. The smart pigs can be inserted into a pipe system at one point and "caught" far down the line. The use of corrosion inhibitors, material selection studies, and internal coatings are mainly used to control corrosion in piping while anodes along with coatings are ...
Trump and his team have signaled opposition to some of Ukraine's recent attacks on Russian soil. Trump's Ukraine envoy said this week that the killing of a Russian general was outside the rules of ...
