What is an ILI and pig?

What is an ILI and pig?

Intelligent Pigs or Smart Pigs are used to inspect and collect a variety of data about the condition of a pipeline, this is called an In-Line Inspection or ILI. Pig Location and location of intrusions and debris. Inertia of pig. Location and depth of damage, wall thickness variation etc. Debris location.

What is ILI tool?

Pipeline Inspection (In-line) In-line inspection (ILI) tools, sometimes referred to as “intelligent” or “smart” pigs, are used to inspect pipelines for evidence of internal or external corrosion, deformations, laminations, cracks, or other defects.

What is ILI inspection?

In-line inspection is a technique used to assess the integrity of natural gas transmission pipelines from the inside of the pipe and is used by Southern California Gas Company (SoCalGas) as part of its ongoing pipeline integrity program. This will further enhance SoCalGas’ pipeline system safety.

What is ultrasonic pig?

Ultrasonic Pigs detect abrasion of the wall thickness due to corrosion or abrasions well as cracks in the material within pipeline systems without severely restricting operation.

What is Ili for pipelines?

In-line Inspection (ILI) involves the evaluation of pipes and pipelines using “smart pigs” (both tethered and non-tethered) that utilize non-destructive examination techniques to detect and size internal damage.

What is a smart pig pipeline?

Smart Pigs are inspection devices that record information about the internal conditions of a pipeline. Smart pigs are inserted into the pipeline and are pushed along by the flowing product. Here a smart pig is being readied for insertion into the pipeline. Magnetic sensors are used to examine the. pipeline.

What is an ILI for pipelines?

In-line Inspection (ILI) involves the evaluation of pipes and pipelines using “smart pigs” (both tethered and non-tethered) that utilize non-destructive examination techniques… Pipeline Integrity Management (PIM) is the cradle-to-grave approach of understanding and operating pipelines in a safe, reliable manner.

What is pipeline in-line inspection?

In-line inspection refers to a preventative maintenance examination of pipelines to identify corrosion, cracks and other defects that may result in catastrophic failure of the structure. It is a form of nondestructive examination. In-line inspection may also be known as line inspection.

What is intelligent pigging?

Intelligent Pigging is an inspection technique whereby an inspection probe, often referred to as a “smart” pig, is propelled through a pipeline while gathering important data, such as the presence and location of corrosion or other irregularities on the inner walls of the pipe.

What is a smart pig?

Smart Pigs are inspection devices that record information about the internal conditions of a pipeline. They may measure several different things from inside of the pipeline, including restrictions and deformations of the pipe, as well as metal loss. Here a smart pig is being readied for insertion into the pipeline.

What is a clean pig?

The term ‘clean pigs’ describes animals that are young or castrated, as opposed to mature boars or sows used for breeding and that are slaughtered at the end of their production lives.

What does pigged out mean?

to eat greedily
intransitive verb. : to eat greedily : gorge.

What’s the difference between MFL and UT pigs?

Typically UT intelligent pigs require lower flow rates whereas MFL pigs can accommodate much higher flow rates. Intelligent pigs have a specific temperature range in which they can function properly due to onboard electronic equipment.

Which is better Dacon or UT intelligent pigging?

Whilst Dacon provides both techniques our recommended method where the pipeline parameters permit is to use UT Intelligent Pigging for its higher accuracy and easier mobilization. UT tools are well suited for heavy walled pipe. UT tools do require a liquid couplant through which ultrasonic pulses can travel to and from the pipe wall.

What does intelligent pig stand for in pipeline inspection?

In-line inspection (ILI) tools, sometimes called as “intelligent” or “smart” pigs, are advanced inspection technology that used to inspect pipelines for evidence of internal or external defect such as corrosion, laminations, deformations, cracks, or other defects. Pig is short for Pipeline Inspection Gauge.

Which is an example of an ili pigged line?

With sufficient planning and budget, any line can be pigged if the integrity benefits of the ILI data justify the difficulty and expense that is necessary to guarantee tool passage. For example, Figure 1 shows a 4 in. ‘unpiggable’ piping that contains back-to-back S, mitred and 1D bends.
