What is PIG?
The name refers to a mechanical device that can be inserted into a
pipeline and used to carry out pre-defined tasks (depending upon its
construction) at critical points, or along the full length of the pipeline.

Bends
Bends
• Mitre bends Should not be used.
• Short radius bends/elbows Should not be used.
• 1.5 D bends OK for Foam, spheres, gel
and special design pigs.
• 3 D bends OK for 12” and above.
• 5D bends OK for all pigs 6” – 10”.
• 10D bends OK for all pigs 4” diameter
and below.
• Field bends Not normally a problem
Wall Changes
Tee’s
Tee’s
• Pigging bars are fitted to ensure pig does not enter the Tee
offtake
• Pigging bars are fitted to Tee when offtake is 50% or greater
than main pipeline diameter

Valves
• Ball valve: Full bore solid ball.
• Gate valve: Concentric full bore w/ no gaps.
Valves
Gate valves can be pigged
Note:
It should be taken of the gap between
seat rings
Valves
Ball valves can be pigged
Note:
It should be Full bore solid ball.

Pig
• In-Line Inspection/Caliper Pig
A caliper tool continuously measures the
inside diameter of the pipeline through
an array of sensing fingers that are
spring loaded to hold them in contact
with the pipe wall.
Pig
• In-Line Inspection/MFL Pig
Magnetic Flux Leakage technique can be used either liquids or
gases and can measure metal loss, even in relatively thin wall
pipes.
Pig
• In-Line Inspection/UT Pig
UT Pig can generally be used in
homogeneous liquids but they are able
to measure much heavier wall
thicknesses than is possible with some of
the magnetic flux pigs.
Pig
• In-Line Inspection/Crack Detection Pig
The tool uses the 45º shear-wave inspection technique to detect
cracks regardless of their width – from hairline cracks to wide
opening cracks. It is so sensitive it can reliably detect cracks,
scratches and grooves
