Air Blowing Services


Air blows is a relatively new technology in the power plant construction industry. The use of air blows must be worked into the schedule early in the preparation process, to ensure that proper cleanliness specifications are issued to all vendors supplying portions of the steam generation system. Mill scale must be completely removed and proper welding techniques must be employed during the erection of the piping in preparation of air blows. Mill scale removal that utilizes chemical cleaning is often recommended to ensure the surfaces are adequately prepared for the air blows. A solid passivation layer on the piping will prevent flash rusting during the air blows.



We provide studies to identify the pressure required to achieve proper disturbance factors, pump-up times, blow-down times, required exit piping sizes, disturbance factors in all portions of the flow path and the order in which the piping systems should be blown.
