Frequency and duration of corrosion mitigation or prevention projects affect the bottom line. Follow the success of power plants around the world using Sponge-Jet composite abrasives throughout the facility:
Achieve the superior surface preparation required by high-performance coatings to enable maximum adhesion and life-expectancy. Increase profits by extending coating life.
A coating change to already delivered wind turbines required swift action to remove/reapply a new system before installation; Sponge-Jet, the only option, on the internals of the steel tower, employed Silver 30 Sponge Media™ abrasive which created an Sa3 (NACE 1 / SSPC SP-5) White Metal Blast cleanliness level and 65micron (2.5mil) profile.
Sponge Blasting navigates live high-voltage wires, multiple transformers and ground structures, strong coastal winds to blast corroded zinc-coated steel structure of a Chilean sub-station,. Images show the ease of containment and media collection – for reuse.
What started as a fire restoration project turned into a major coatings overhaul and in process a lead paint abatement project at Port Jefferson Power Plant (New York); the lead dust-suppressing characteristics of Sponge-Jet helped extend this soot/creosote removal project to lead-paint abatement on walls, furnace, stairs and columns.
Alstom energy company management (Spain), formerly against using abrasive blasting to clean its turbine parts, quickly switched from manual wiping with Scotch-Brite™ to mechanical blasting with Silver 320 Sponge Media™ abrasives when it learned blasting took place just meters from the base and saw the consistency and quality of the cleaned surface.
The dry, low dust creosote-cleaning benefits of Sponge-Jet are sweeping through ethanol plants as facilities try to reduce maintenance downtime; whether it’s this regenerative thermal oxidizer or motors, dryers, dampers or air-to-air preheaters, Sponge-Jet micro-abrasive cleaning is much more efficient than any wet solution do to the simplicity of job staging and clean-up and the enhanced visibility during cleaning – which collectively accelerates total job duration.
Coating repair on this wind turbine nacelle prior to assembly in a mid-west (US) wind farm. Note near perfect visibility and low media rebound, allowing for a more productive environment - promotes clean consistent White Metal Blast Cleaning levels.
The cleaning of accumulated grease and soot from critical motors like this 1,000hp FD fan motor in an ethanol plant extends its working life and efficiency; the contractor, during a timed shutdown, Sponge Blasted this one in situ and with pressure to complete the project prior to the line starting back up.
Sponge-Jet was used at coal-fired plant, Alabama Power just after a turbine fire contaminated the plant’s ceilings. While emergency replacement turbines sit below, a dry, dust-controlling cleaning method became critical. Sponge-Jet met the challenge and actually profiled ceiling substrates so they could also be repainted.
Sponge-Jet and a pipe pig are used to dry clean refinery process pipe interiors in the world’s first sustainable commissioning; the process is saving millions of liters of water and millions of dollars by reducing water transportation, processing and treatment requirements.
