New Construction of Concrete Chimneys (New Construction of Cement Chimneys, New Construction of Concrete Chimneys)

Business Scope:
1. Undertake the construction, installation, reinforcement, demolition, and heightening of various chimneys and water towers (brick, concrete, steel structure); reinforcement of concrete shell slipforms; tilt correction; replacement of inner linings; cleaning and dust removal; painting of aviation warning color rings; 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 inner and outer walls of chimneys, cooling towers, water towers, urea granulation towers, and silos.

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

4. Exterior wall cleaning, washing, repair, decoration, coating, and high-temperature-resistant fireproof coating for high-rise buildings, skyscrapers, factories, and coal conveyor 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 concrete floors; repair, cleaning, and waxing 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 systems, channel dredging, land reclamation, port yard storage, embankment revetment, underwater blasting and clearing of reefs, and corresponding projects such as silos, underwater foundations and bases, earthwork, navigation markers, trestles, coastal and offshore hydraulic engineering, installation of port handling equipment, installation of navigation structure equipment, underwater excavation, heavy lifting, and inland river salvage and obstacle clearance.

7. Desulfurization and Anti-Corrosion
Coal used in thermal power plants contains sulfur, which produces SO2 during combustion, affecting air quality after emission. Due to environmental pressures, flue gas desulfurization (FGD) has become the primary method for controlling SO2 emissions in thermal power plants. Therefore, FGD systems have become essential supporting projects in many power plants. Those previously built without such systems are now being retrofitted with FGD installations. Wet desulfurization anti-corrosion for the inner linings of chimneys, absorption towers, and flue ducts in thermal power plants, using acid-resistant borosilicate foam glass brick linings, vitrified ceramic tiles, glass flake anti-corrosion, spray polyurea, OM coatings, and acid-resistant mortar for anti-corrosion; repair of cracks and leaks in chimneys and flue ducts.
