High Pressure Impulse Steam Blow
This is the traditional method used to clean out
steam piping
- System is pressurized to pre-engineered level by firing the boiler and generating steam.
- This method is fast and efficient. A quick opening valve is used to build pressure up and once the target pressure is attained the valve is opened and the steam flows though the piping into the atmosphere.
- A "target" is used downstream to check cleanliness of the lines.
- Impulse releases are repeated until a clean target is obtained.
Considerations:
- Temporary pipe design must be properly engineered and supported to counteract dynamic forces.
- Cleaning forces have short durations.
Cogen Cleaining Technology Inc.
Number ONE for a reason
Considerations:
- Advanced 3D Engineered temporary piping drawings
show exact specifics on the layout and proceedures
of the steam blow.
- Calculations of flow, stress, and strain are done
to ensure the procedure goes as smoothly as
possible.
- Knowledgeable staff with years of experience to
help our clients through every step of the process.

Continuous Low Pressure Steam Blow
Continuous flow of steam from the boiler or
steam
header to achieve stable blowing conditions
- Pressures are maintained at low levels, usually less than 150 PSIG at the drum, and target velocities have comparable velocities as the permanent pipe outlet. Disturbance Factor is high at lower steam flow rates.
- Targets are placed in temporary piping with same diameter as permanent piping headers to provide verifiable results.
Considerations:
- High confidence.
- Steady state steam conditions run at same level throughout.
- Safer with no dynamic only thermal stress forces on piping systems.
Additional Steam Blow
A combination of high or low pressure steam blow
coupled with Hydrolazing (a high pressure water jetting
away of permanent steam pipe mill scale).
Considerations:
- Duration of steam blow reduced by 45%-55%
which results in:
- Demin water consumption significantly reduced.
- Significant fuel savings to generate steam.
