Cleaning is a vital aspect of the integrity management of pipeline networks and is necessary at every stage throughout a pipeline’s lifecycle. Each pipeline is unique, so cleaning needs may vary depending on the pipeline’s operational purpose and lifecycle stage. Failure to clean a pipeline at regular intervals leads to reduced efficiency and may result in damages that impact its integrity.

Why Clean:

Efficient pipeline operation is dependent on two fundamental aspects: 1) continuous transportation of the medium and 2) maintenance of the internal diameter to ensure optimal flow of the medium. There are several factors that can seriously impact the efficiency of a pipeline, including:


  • Buildup of deposits in the line which can cause damage by abrasion or encourage corrosion under deposits
  • Product contamination
  • Dirty pipeline surfaces prohibit corrosion inhibitors from being applied consistently
  • System contamination can complicate the preparatory work necessary to ensure high quality data from an inline inspection (ILI)


Failing to clean your pipeline can dramatically affect the efficiency, safety, and reliability of the entire network. Foreign matter and buildup can damage the integrity of a pipeline, encourage the formation of corrosion and pipe thinning, and will almost certainly reduce throughput.

When to clean:

The cleaning requirements for a pipeline during its life cycle are many and varied, depending on what stage in the life cycle it is in. The stages include:

  • Pre-Commission Cleaning: After construction and prior to commissioning of the new pipeline
  • Commissioning Cleaning & Service Preparation: Dewatering, drying, and conditioning
  • Operational Cleaning
  • Change of Service Cleaning & Preparation
  • Cleaning prior to the Cessation of Production (COP)
  • Decommissioning Cleaning prior to Abandonment, Recovery and/or Recycling

During any of these stages debris can deposit & collect within the line, if this material is not removed it can not only effect the efficiency of the line but perhaps even contaminate product or hinder corrosion inhibitors from performing properly.

Contaminants can vary from wax, scale, corrosion products, hydrates, emulsions, produced sands, and even water. The best time therefor to clean a pipeline is often and regularly. Applying a consistent routine maintenance program can significantly increase the efficiency and operational life of entire pipeline network.
