FRP Wastewater Tank Cover

FRP wastewater tank cover is also called the sewage tank cover and the odor collection cover, it is a composite material product made of E-glassfiber, resin by hand lay-up process, SMC process.

Application-FRP Wastewater Tank Cover

FRP wastewater tank cover is mainly used in sewage treatment system engineering, petrochemical industry, fertilizer, industrial wastewater, medicine, breeding and other industries

Advantages and features-FRP Wastewater Tank Cover

(1) Excellent corrosion resistance, temperature resistance, and heat preservation performance.

(2) Lightweight, high strength, easy to install

The specific gravity of FRP products is only 1/3 to 1/4 of that of steel, and the strength is very high. Therefore, the transportation and installation of FRP equipment are very convenient.

(3) Low operation and maintenance costs

Glass copper products have good corrosion resistance, and do not need regular anti-corrosion and other maintenance like metal products. Obviously, the maintenance cost is greatly reduced during the operation of the equipment.

(4) Anti-ultraviolet rays: The surface of the glass fiber reinforced plastic arched cover plate is sprayed three times with colored gel coat resin. The colored gel coat resin contains high-strength anti-ultraviolet agent to obtain the anti-ultraviolet effect, and it will not fade after long-term use.

(5) Other excellent properties: impact resistance, maintenance-free, easy processing, non-slip safety, insulation and heat insulation, etc.

(6) The cover is divided into small pieces to facilitate manual handling for disassembly. The small cover plates and the cover plate and the top surface of the pool are connected in a sealed manner to prevent the leakage of odor.

Specification-FRP Wastewater Tank Cover

According to the user's requirements and the size of the sewage tank, other shapes such as curved cover and flat cover can be made. The color can also be made into a variety of colors according to the needs to meet the different needs of users.

Metal parts: The truss beam adopts Q235, the joints are rust-removed to S grade, and the exterior is coated with chlorosulfonated paint for corrosion protection. The connectors are made of 304 stainless steel.

Structural requirements: FRP canopies have different spans according to design requirements to ensure sufficient load-bearing strength and prevent rainwater from accumulating on the top of the pool. Due to the different specifications of the pools, through stress analysis and calculation, it is concluded that the arch heights of the FRP canopies of different spans are different, and the safety factor is 1.15. The design width of a single piece of FRP cover is 1.0m-1.5m, and there are upturned flanges on both sides, which improves the overall rigidity of the FRP cover and facilitates the connection between each piece. The flat support feet at both ends adopt pressure plate type anchor bolts. Connection method: The glass fiber reinforced plastic cover is designed with its own reinforcing ribs to enhance the bearing capacity;

Flexural strength: ≮200Mpa molding density: ≮1800kg/m³;

Fire rating: BI level. Flame retardant performance, oxygen index ≥30 Deflection ≯1%. Load 3KN/ m²

Comprehensive physical properties: Barcol hardness: ≮50 Roughness: 0.0084; Elongation at break: 0.8% Wear resistance: ≥99.98%; Poisson coefficient: 0.3 Wear allowance: ≮1.5mm; Oxygen index: ≥30 Temperature resistance Capability: -20~80℃ 2.3.3 Anti-static and explosion-proof;

The treated gas contains flammable and explosive volatile organic compounds such as hydrocarbons and VOCs, and airtight facilities must be equipped with anti-static and explosion-proof measures.

Appearance: The outer surface should contain a smooth gel coat resin layer of light stabilizer, anti-aging agent and ultraviolet absorber. The surface should be smooth, free of burrs, cracks, scars, no fiber exposed, uniform color, and there should be no diameter on the inner and outer surfaces. Bubbles larger than 2mm, and visible bubbles with a diameter of 2mm shall not exceed 2 per square meter. The inner surface should have a smooth and level resin-rich layer, all parts should be cut neatly and smoothly, the thickness should be uneven, no delamination, and the cut section should be sealed with resin.
