Chimney Maintenance (Chimney Maintenance Company,Chimney Maintenance Construction)

Business Scope:

1. Undertake the construction, installation, reinforcement, demolition, and heightening of various chimneys and water towers (brick, concrete, steel structure); concrete shell slip-form reinforcement; tilt correction; inner lining replacement; cleaning and dust removal; aviation marking color ring painting; replacement and reinforcement of exposed metal components such as ladders, platforms, protective nets, lightning rods, and anti-corrosion painting maintenance.

2. Cleaning, repair, anti-corrosion, waterproofing, and moisture-proof leak sealing for the internal and external walls of chimneys, cooling towers, water towers, urea granulation towers, detoxification towers, and silos.

3. Surface treatment and specialized anti-corrosion for metal structures such as TV towers, transmission towers, microwave towers, substation frameworks, bridges, various gantry cranes, steel beam roof trusses, gas tanks, (oil, acid, alkali, solvent) storage tanks, and chemical equipment.

4. Exterior wall cleaning, repair, decoration, coating, and high-temperature fire-resistant coating for high-rise buildings, mansions, factories, and coal conveying trestles.

5. Flooring Engineering
Undertake various terrazzo floors, epoxy, wear-resistant, hardened, dust-free, colored, anti-static, and metal (emery) cement-based wear-resistant floors; non-slip vibration-free driveways and colored stamped decorative floors; repair, cleaning, and wax maintenance for various industrial floors.

6. Underwater Salvage
Engage in the construction of river, sea, and port terminals; dry docks, shipways, slipways, ship locks, navigation lift equipment, channel dredging, land reclamation, port area storage yards, embankment revetment, underwater rock blasting, and reef clearing projects; as well as corresponding silos, underwater foundations and bases, earthwork, navigation markers, trestle bridges, coastal and offshore marine engineering; installation of port loading and unloading equipment, navigation building equipment installation, underwater excavation, heavy lifting, inland river salvage and obstacle clearance projects.

7. Desulfurization and Anti-Corrosion
Coal used in thermal power plants contains sulfur, which produces sulfur dioxide during combustion, significantly impacting the atmospheric environment after emission. Due to environmental pressures, flue gas desulfurization (FGD) has become the primary method for controlling sulfur dioxide in thermal power plants. Therefore, FGD flue gas desulfurization units have become essential supporting projects in many power plants. Those previously built without such units are now installing them. Wet desulfurization anti-corrosion for the inner linings of thermal power plant chimneys, absorption towers, and flue ducts; anti-corrosion using acid-resistant borosilicate foam glass brick linings, vitrified ceramic tiles, glass flake anti-corrosion, spray polyurea, OM coatings, and acid-resistant mortar; repair of cracks and leaks in chimneys and flue ducts.
