Compressed air can be utilized in a wide variety of applications within the Energy and Petrochemical Industries. Applications include the cleaning and commissioning of new facilities, drying pipelines following hydro test, pressure testing, heating of large systems, as well as the cleaning and commissioning of new build systems.

Compressed air is a very effective method of removing significant deposits of dirt, welding slag and construction debris from the process piping systems. In addition, systems can also be checked for integrity by confirming the absence of leaks, passing valves during the pressurization. The system to be cleaned is prepared and then pressurized to the designated pressure. For air blowing the pressure is then rapidly released, creating significant line velocity and movement of debris to the engineered collection point outside the system.

Following completion of a successful hydro test, pipelines are de-watered and prepared for use. Gas and finished product plipeines must be cleaned and dried prior to the introduction of the product to be transported. Compressor spreads can provide large volumes of -80 C Dew point air, combined with foam and brush pigs can clean and dry pipelines successfully to a very high standard.
