T19-1 - Pig caliper gauge

Functional description:

The pig caliper gauge has two different diameters. A worn pig fits through both sides of the gauge. A brand new pig fits into the "GO" side, but not into the "NO GO" side. With the pig caliper gauge the pig's minimum pre-tension is measured in order to make sure that it is sufficient to obtain a good pigging result.

The use of worn pigs can lead to following problems:

• More product residuals in the pipeline, caused by insufficient stripping performance of the pig

• Product mixture

• Aging products in the pipeline

• More sediments in the pipeline
