English

Subject field(s)
  • Long-Distance Pipelines
  • Petroleum Technology - Instrumentation
  • Petroleum Technology - Maintenance
DEF

A special spiral apparatus that is sent through a pipeline to clean out the sediment.

CONT

Scraper traps and launchers are installed parallel to the line. From these locations scrapers or cleaning spheres ("pigs") may be put into the line and removed. "Pigs" are used both in cleaning operations and in maintaining batch separation of different commodities passed through "multiple products" lines.

CONT

A typical cleaning pig - also called a "line scraper" or "go-devil" - travels with the flow of product in the line, cleaning the walls of the pipe by means of blades or brushes affixed to it.

OBS

[There exists no definitive explanation to the use of the term "pig":] there are stories of the ancient Romans cleaning aqueducts using pig skins. There are also stories of pioneers using bundles of straw wrapped with barbed wire to clean out early oil pipes. The scraping of the wire in the pipe sounded like pigs squealing.

  • Estimating (Construction)

CONT

There are two main types of pressurized structure but really unambiguous descriptions of them do not yet exist: (a) those that are held up by ribs or inflated "tyres" and therefore do not need an air lock to allow inward or outward access; (b) those that do need an air lock, have no inflated ribs and therefore must be held up by an internal air pressure slightly above atmospheric .... The ribbed structures are called "air inflated" and the non-ribbed ones "air supported".

French

Domaine(s)
  • Évaluation et estimation (Construction)
  • Architecture civile
CONT

L’expression structure gonflable s’applique à toute structure déformable, dont la rigidité dépend uniquement de la pression intérieure. [...] Un grand nombre d’objets répondent à cette définition, tels que les pneus, bateaux pneumatiques, ballons, structures à ossature gonflable, à double paroi, et à simple paroi.

OBS

Il existe divers types de structures gonflables : l'enveloppe entièrement close, amarrée par un filet et soutenue par la surpression de l'espace interne; la couverture solidaire du sol en périphérie [...]; la couverture fixée à une ossature gonflable. Sauf dans le dernier type où l'espace n’ est pas surpressé, l'accès se fait par un sas ou par une porte tournante.

The ribbed structures are called "air inflated" and the non-ribbed ones "air supported". ... The air-supported structures ... are often used as a temporary shelter .... The edges must be weighted, or buried in soil which comes to the same thing, so as to counterbalance the upthrust on the roof skin of the small excess pressure.
