At the present time pipeline systems are the most efficient method for the bulk transportation of both liquids and gases.

 However to maintain a pipelines efficiency the following two basic rules need to be followed.

 1/ The pipeline needs to run continuously.

 2/ Pipeline throughput must be obtained at both the lowest capital investment and lowest  operational cost.

To maintain the two basic rules a pipeline should be ‘pigged’ on a regular basis using one or more types of pipeline pigging tool, depending upon the operational parameters.

 The running of pipeline pigging tools helps to maintain the two basic rules as follows:

• Removes any harmful media.
• Removes liquid and solid debris.
• Prevents build up of flow restrictions.
• Prevents the need for long term, costly shutdown periods.

Regular pipeline pigging operations should form part of a pre-determined maintenance plan to be carried out at set time intervals and culminating in a inspection programme utilising an inline inspection tool that with provide definitive wall thickness measurement data.
