Double Protection Against Dynamic Seal Leakage/Valve Actuator, Valve Stem and Floating Roof Tank VOCs Emissions
non-metallic expansion joint secondary containment system can provide an effective method for protecting valve actuators, valve stems, and floating roof tank leaks, as well as minimizing VOC (Volatile Organic Compounds) emissions. Here’s how such a system can be beneficial:
- Protection of Valve Actuator & Valve Stem: Isolation from Environmental Factors: Non-metallic expansion joints, made from materials like rubber or composite fabrics, can provide isolation from corrosive elements, reducing the risk of damage to valve actuators and stems. Vibration Absorption: These joints absorb vibrations caused by fluid flow, reducing mechanical stress on valve components and extending their lifespan. Thermal Expansion Management: Expansion joints accommodate thermal expansion and contraction, ensuring that valve components are not subjected to undue stress caused by temperature changes, which could otherwise lead to failure.
- Preventing Leaks in Floating Roof Tanks: Secondary Containment: Floating roof tanks, typically used for storing volatile liquids, are susceptible to leaks at the seals around the roof and tank walls. A non-metallic expansion joint system can create a containment barrier that captures any leakage or overflow. VOC Emission Reduction: The joint system can contain vapor emissions that occur due to temperature fluctuations or pressure changes in the tank. By isolating these emissions, it helps to ensure that VOCs are kept inside the containment area, reducing the release into the atmosphere.
- Environmental Protection and VOC Management: VOC Containment: Non-metallic materials used in expansion joints are often designed to be impermeable to VOCs, helping to reduce harmful emissions from tanks or piping systems. Durability & Chemical Resistance: Materials like fluoropolymer or rubber are highly resistant to chemicals and hydrocarbons, making them ideal for environments where VOCs are present. Flexibility for Tight Seals: These expansion joints can be tailored to provide a tight, flexible seal, preventing the escape of volatile substances during tank filling, draining, or during changes in environmental conditions.
- Advantages of Non-Metallic Expansion Joints: Lightweight and Cost-effective: Compared to metallic alternatives, non-metallic joints are generally more affordable and easier to install. Reduced Maintenance Needs: Due to their flexibility and resistance to corrosion, non-metallic joints require less frequent maintenance than their metal counterparts, leading to reduced downtime. Customization: Non-metallic expansion joints can be custom-made to fit specific valve sizes, tank configurations, and environmental conditions, ensuring optimal protection and containment. Key Considerations: Material Selection: Depending on the specific application (e.g., type of fluid or gas), choosing the right non-metallic material that can withstand the operational temperature, pressure, and chemical exposure is critical. Design and Installation: Proper installation of the expansion joint system is necessary to ensure the effectiveness of the containment. Improper installation could lead to leakage or system failure. By incorporating a non-metallic expansion joint secondary containment system, industries can significantly improve safety, environmental compliance, and operational efficiency by preventing leaks and emissions
