1. Free venting for automatic pressure balance: Straight or elbow structure provides an unobstructed gas passage, automatically balancing tank pressure without moving parts, ensuring high reliability.
2. Rain and dust protection design: Top rain cover prevents rain, dust, and debris from entering the tank; optional insect screen prevents insects and birds from entering.
3. Optional flame arrestor function: Can be equipped with a stainless steel corrugated flame arrestor layer to prevent external flames from entering the tank through the vent pipe, meeting fire protection codes.
4. Large venting capacity with low pressure drop: Large flow cross‑sectional area minimizes gas flow resistance, meeting venting requirements during rapid filling and discharging.
5. Multiple corrosion‑resistant materials: Housing available in carbon steel, stainless steel, aluminum alloy, or plastic (UPVC/PP) to suit various media such as water, oil, chemicals, and outdoor environments.
6. Simple structure with easy installation and maintenance: Standard flange or threaded connections for easy installation; removable rain cover and insect screen for convenient cleaning, low maintenance cost.
7. Wide application range: Suitable for vent piping of atmospheric tanks in water treatment, petrochemical, food and beverage, environmental protection, and other industries.
8. Compliant with relevant standards: Designed and manufactured according to SH/T 3007 “Design specification for tank farm of petrochemical storage and transportation system” and other standards.
