Background

Air Blowing - Air Blows

Air blowing of natural gas and/or steam lines is a service that uses compressed oil free air. A quick opening valve is used to rapidly release the pressure to atmosphere. High and Low set-points are determined by the system being cleaned. CCT can also provide a pneumatic target inserter to eliminate the use of a manual target bar. Targets can be made out of any metal desired and in any length to accommodate different line sizes. Air Blows have been accepted across the country as a safe alternative to using natural gas to clean fuel supply lines to CTG’s and Boilers. Air Blows on steam lines have the economic impact of no water consumption and fuel cost.

Surge Flushing

CCT’s High Velocity Surge Flush is designed to be a, low pressure quick method for achieving identifiable results in long runs of piping. This method requires very little water and can attain velocities of 200 feet per second. The surge flush method will remove construction debris, semi adherent material, and safely transport the removed items out of the system. CCT uses an air receiver, quick opening valve and temporary pipe to control the exiting water capsule.

This method allows for quick cleaning of piping systems without need for disposal of cleaning solutions.
Surge flushing is typically more effective removing/cleaning semi adherent material on the inside walls of piping as a small amount of water is used in the process. Cleanliness is approved by the cleanliness of the water/air exiting the pipe and visual inspection of the piping in visual accessible areas.

Setting Up the Equipment for the Air Blow

We used 18 Compressors, 9 Boosters, 9 Coalescent Filters and 14 Fuel Tanks.
