Product Description: Due to fluctuations in raw material prices, the specifications and prices may vary. For specific quotations, please contact our sales staff. Thank you.What are the standard parameters and installation specifications for mining ventilation ducts? The main parameters of mining negative pressure ventilation ducts include specifications and dimensions, ventilation performance, coated fabric properties, etc. The resistance of coated fabric positive and negative pressure mining ventilation ducts for tunnels accompanies achievement. Mining ventilation ducts come in diameters of 500mm, 600mm, 800mm, 1000mm, and can also be custom-processed according to customer requirements. Common colors are black, sky blue, and orange. We pay attention to every detail of each product, trust me, you won’t regret it. Buying means earning!Uses of coal mine positive and negative pressure ventilation ducts:Used for exhaust-type directional ventilation in coal mines, tunnels, subway projects, ships, and underground local areas;The specifications and dimensions of mining negative pressure ventilation ducts are as follows:Inner diameter: 300mm, 400mm, 500mm, 600mm, 800mm, 1000mmLength: 5 meters, 10 meters, 20 meters, can be customized according to customer requirementsVentilation performanceThe hundred-meter wind resistance and air leakage rate for ducts of different diameters are as follows:300mm diameter: hundred-meter wind resistance ≤1728.0 N·s²/m, air leakage rate ≤5.0%400mm diameter: hundred-meter wind resistance ≤134.0 N·s²/m, air leakage rate ≤4.0%500mm diameter: hundred-meter wind resistance ≤134.0 N·s²/m, air leakage rate ≤3.5%600mm diameter: hundred-meter wind resistance ≤54.0 N·s²/m, air leakage rate ≤3.0%800mm diameter: hundred-meter wind resistance ≤13.0 N·s²/m, air leakage rate ≤2.5%1000mm diameter: hundred-meter wind resistance ≤4.0 N·s²/m, air leakage rate ≤2.0%Warp and weft breaking strength, can withstand 8000Pa wind pressure, meeting the requirements for high-wind air delivery. Mining ventilation ducts are divided into positive pressure ducts and negative pressure ducts.Isn’t this analysis clear? Positive pressure ducts are 10M per section with no skeleton in the middle; negative pressure ducts are composed of countless steel rings, also commonly known as skeleton ducts. Positive pressure ducts blow air outward, while negative pressure ducts suck air inward. This type of duct can withstand a certain level of negative pressure, can be used for exhaust ventilation, and has retractable characteristics, making it more convenient to use than iron ducts. Choose us for mining positive pressure ducts, we prove our worth with strength, not exaggeration! New and old customers are welcome to cooperate with us, we will not let you down!Contact: Manager Hu  Contact Information: 16653525598 more>

Product Description: New Construction of Concrete Chimneys (Concrete Chimney New Construction Company, Concrete Chimney New Construction Services)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; 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, 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, storage tanks (for oil, acid, alkali, solvents), and chemical equipment.4. Exterior wall cleaning, washing, repair, decoration, coating, and high-temperature fire-resistant paint application for high-rise buildings, skyscrapers, factories, and coal conveyor trestles.5. Flooring EngineeringUndertake 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 wax maintenance for various industrial floors.6. Underwater SalvageEngage in the construction of river, sea, and port terminals; dry docks, shipways, ship locks, ship lifts,航道 dredging, land reclamation, port area storage yards, embankment revetments, underwater rock blasting, and reef clearance projects; as well as corresponding silos, underwater foundations and bases, earthwork, navigation aids, 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 and Anti-CorrosionCoal used in thermal power plants contains sulfur, which produces sulfur dioxide during combustion, severely impacting the atmospheric environment after emission. Due to environmental pressures, flue gas desulfurization (FGD) has become the primary method for controlling sulfur dioxide emissions 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 being retrofitted with FGD systems. Wet desulfurization anti-corrosion for the inner linings of thermal power plant chimneys, absorption towers, and flues; anti-corrosion using acid-resistant borosilicate foam glass brick linings, vitrified ceramic tiles, glass flake anti-corrosion, spray polyurea, OM coatings, and acid-resistant mastics; repair of cracks and leaks in chimneys and flues. more>
