Fiberglass Reinforced Plastic Damper is a critical component in ventilation systems, primarily constructed from fiberglass reinforced plastic (FRP). It offers exceptional corrosion resistance, lightweight yet high strength, and excellent aging resistance. Its core function is to regulate or block airflow to control ventilation system air volume and pressure. It is widely used in corrosive environments such as chemical processing, power generation, and wastewater treatment, or in scenarios requiring long-term stable operation.

Technical Characteristics:

• Material Advantages: Constructed from fiberglass-reinforced plastic, it offers significantly higher resistance to acid and alkali corrosion than metal valves, with a service life exceeding 15 years.
• Structural Design: Typically equipped with flange connections (e.g., HG/T21633 standard flanges), ensuring excellent sealing performance and pressure ratings ranging from 1.0 to 3.5 MPa.

Performance Parameters:

• Operating temperature range: -30°C to 120°C.
• Common diameters: 200-2000mm.
• Custom non-standard sizes available.

Application Scenarios:

• Chemical Industry: Handles corrosive gases like chlorine and hydrogen sulfide.
• Marine Engineering: Resists salt spray corrosion, suitable for vessels or offshore platforms.
• Environmental Protection: Used with desulfurization towers and exhaust gas treatment equipment.

Selection Considerations:

Select the appropriate MPa rating based on system pressure; specifications above 1.6 MPa are recommended for high-pressure applications.

Corrosive media require specified composition; certain strong oxidizing agents necessitate specialized resin formulations.

Ensure symmetrical tightening of flange bolts during installation to prevent cracking from stress concentration.

Industry Trends: The market increasingly favors modular designs. Some premium products integrate electric actuators for automated control, while lightweight construction (40%-60% lighter than metal valves) emerges as a key selling point. Beihai Fiberglass offers such products featuring HG/T21633 standard flanges—capable of withstanding high pressure and corrosion, lightweight, and resistant to aging.
