Олег, большое Вам спасибо за такой развернутый ответ!

What are 'pigs' used for? Pig varieties

A "pig" in the pipeline industry is a tool that is sent down a pipeline and propelled by the pressure of the product flow in the pipeline itself. There are four main uses for pigs:

1. Physical separation between different fluids flowing through the pipeline
2. Internal cleaning of pipelines
3. Inspection of the condition of pipeline walls (also known as an Inline Inspection (ILI) tool)
4. Capturing and recording geometric information relating to pipelines (e.g., size, position).

Intelligent pigging

Modern intelligent or 'smart' pigs are highly sophisticated instruments that include electronics and sensors that collect various forms of data during their trip through the pipeline. They vary in technology and complexity depending on the intended use and the manufacturer.

Чтобы охватить все разнообразие этих "свиней", мне кажется, предложенный Юрием и широко употребляемый термин "внутритрубные снаряды" будет весьма уместен -> https://www.google.ru/#newwindow=1&tbs=li:1&q=внутритрубный ...

Евгения, общий контекст и так понятен -> речь идет о:

Pigging in the context of pipelines refers to the practice of using devices known as "pigs" to perform various maintenance operations on a pipeline. This is done without stopping the flow of the product in the pipeline.

These operations include but are not limited to cleaning and inspecting the pipeline. This is accomplished by inserting the pig into a 'pig launcher' (or 'launching station') - an oversized section in the pipeline, reducing to the normal diameter. The launcher / launching station is then closed and the pressure-driven flow of the product in the pipeline is used to push it along down the pipe until it reaches the receiving trap – the 'pig catcher' (or 'receiving station').

Вопрос в том, как именно Вы решите переводить доставшийся Вам исходник - с использованием профессионального сленга ("лупинги" "райзеры", "лаунчеры/лончеры", "ресиверы"), или обычными словами, или сочетанием и того, и другого.

А то ведь в сети и "пиггинг-система"/"пиг-система" встречаются, и, IMHO, 'pigging loops' вполне можно перевести как "пиг-лупинг" - спецам понятно будет. :-)

Коллеги, вот еще контекст:

Pigging loops in subsea
Includes pigging loop in the subsea component manifolding and adjustment of default flowlines to provide a common diameter through the pigging loop.

Все-таки, контуры поршневания?
