Chimney Hooping (Chimney Maintenance and Reinforcement, Chimney Hoop Reinforcement)

Business Scope:
1. Undertake the construction, installation, reinforcement, demolition, and heightening of various chimneys and water towers (brick, concrete, steel structure); concrete shell slipform reinforcement; tilt correction; replacement of inner linings; cleaning and dust removal; painting 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 transmission towers, microwave towers, substation structures, bridges, various gantry cranes, steel beam roof trusses, gas tanks, (oil, acid, alkali, solvent) storage tanks, and chemical equipment.

4. Exterior wall cleaning, washing, repair, decoration, coating, and high-temperature fire-resistant 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 reef clearing projects, as well as corresponding silos, underwater foundations and bases, earthwork, navigation markers, trestles, coastal and offshore marine engineering; installation of port loading and unloading equipment, navigation structure equipment installation, underwater excavation, heavy lifting, inland river salvage and obstacle clearance projects.

7. Desulfurization Anti-Corrosion
Coal used in thermal power plants contains sulfur, which produces SO2 during combustion. Emissions affect the air environment, and due to environmental pressures, flue gas desulfurization (FGD) has become the primary method for controlling SO2 in thermal power plants. Therefore, FGD flue gas desulfurization units have become essential supporting projects in many power plants. Those previously built without such systems are now installing FGD units. 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 mastic; repair of cracks and leaks in chimneys and flue ducts.
