Effective in the removal of construction debris, weld slag, sand, oil, dust, rust and mill scale from critical systems prior to plant start-up.
We optimize our steam blows with quality engineering, and by utilizing the best equipment. Determining pipe sizing and design, pipe routing, steam conditions, noise level, thermal cycling, water quenching, and condensate generation are all factors that – with our proper planning – will ensure a successful steam blow operation.
WHY PERFORM STEAM BLOWING ?
When pipe is fabricated during hot working, a heavy oxide layer forms. This layer is known as mill scale and must be removed from critical systems before putting them into service.
The steam blow method is similar to the exhaustive air blow technique, but the boiler is fired to generate the pressurized steam used to clean the steam path. Specialized quick opening valves and a detailed procedure, along with the design of temporary spools, steam quenching devices, silencers, and debris containing equipment are required to per
form this service.
Dry Silencers are designed to vent up to 900 KPPH of steam while maintaining a 85 dB noise rating or less at 50 ft. from the discharging steam. Other benefits include eliminating or greatly reducing hot water discharge associated with traditional silencers, eliminating fall-out of moisture experience when quenching a traditional steam blow, and reduced equipment requirements and associated construction costs.
ANPAM ENGINEERING can engineer and perform several different types of steam blow methods depending on our clients needs. System piping is modeled and analyzed for proper velocities, pressures, and disturbance factors. Modeling the system leads to verifiable results and compliance with all client and specifications.
ANPAM ENGINEERING has invested a tremendous amount of time and capital in designing our steam blow equipment to ensure we offer the most effective and safest equipment available to our clients. A strong inventory of equipment is readily available worldwide to serve both small scale and large scale projects.
