Petroleum tank valve flange connection EPDM80 rubber gasket
Products Overview Description
This EPDM80 rubber gasket is specially designed for the flange connection of oil storage tank valves, aiming to provide excellent sealing performance to ensure safety and efficiency during oil storage and transportation. EPDM rubber material gives it excellent aging resistance, chemical corrosion resistance and the ability to adapt to various working conditions. It is one of the ideal sealing solutions in the petroleum industry.
Features
1. Excellent aging resistance: EPDM80 rubber gasket is highly resistant to aging factors such as ozone, ultraviolet rays, and weather. In the open environment of petroleum storage tanks or during long-term use, it can effectively prevent aging phenomena such as cracking and hardening, ensure long-lasting and stable sealing performance, and greatly extend the service life and maintenance cycle of the product.
2. Excellent chemical corrosion resistance: It shows good tolerance to petroleum and various additives, common acids and bases and other chemical substances. Whether it is crude oil, gasoline, diesel, or certain corrosive chemicals that may be exposed to during petroleum processing, they will not corrode the gasket or cause its performance to deteriorate, effectively ensuring that it can be used in complex chemical environments. Sealing reliability.
3. Good elasticity and resilience: EPDM rubber with a Shore hardness of 80 maintains good elasticity while providing sufficient sealing contact pressure. When the flange is subjected to pressure or undergoes slight deformation due to temperature changes, the gasket can deform accordingly and quickly return to its original shape after the pressure is released, continuing to maintain a tight seal and effectively preventing oil leakage.
4. Wide temperature range applicability: It can work normally in a wide temperature range from -45℃ to 150℃. Whether it is a low-temperature environment in a cold area or a high-temperature working condition of an oil storage tank in summer or near a heating device, it can maintain stable sealing performance and will not cause sealing failure due to temperature fluctuations, ensuring the stability of the oil storage and transportation system. Intermittent operation.
5. Excellent sealing integrity: The combination of precise dimensional design and high-quality rubber material ensures that the gasket can completely fill the gap between the sealing surfaces during flange connection, forming a continuous and uniform sealing line of defense, effectively preventing The leakage and volatilization of oil comply with the strict environmental protection and safety standards of the petroleum industry.

Applicaion scenarios
Widely used in various types of valve flange connections for petroleum storage tanks, including but not limited to:
1. Storage tank inlet and outlet valves: Ensure that there is no leakage of oil during the process of entering and exiting the storage tank, ensuring the safety and precise control of storage and transportation.
2. Sewage valve: effectively prevents the mixing and leakage of sewage and oil, and meets environmental protection and process requirements.
3. Vent valve: When releasing the pressure in the storage tank or emptying the tank, maintain a reliable seal to prevent petroleum vapor leakage from causing safety hazards and resource waste.
4. Pipeline connection flange: Provides stable sealing performance at the connection point between oil transportation pipelines and storage tanks, maintaining the sealing and stability of the entire oil transportation network.
Installation and maintenance guide
1. Preparation before installation
- Check the flange sealing surface to ensure it is flat, smooth, free of damage, oil and impurities.
- Check whether the size of the rubber gasket matches the flange specifications, and if necessary, perform trial installation adjustments.
2. Installation points
- Gently place the gasket on the flange sealing surface, making sure it is positioned accurately and is not offset or twisted.
- Tighten the flange bolts evenly and gradually in diagonal order to avoid gasket damage or poor sealing caused by uneven local stress. The tightening torque should be strictly controlled according to the flange specifications and system pressure requirements. Generally, refer to relevant standards or equipment manufacturer recommendations.
3. Maintenance suggestions
- Regularly inspect the valve flange connection parts to observe whether the gasket shows signs of leakage (such as oil leakage, gas leakage, etc.), aging (such as surface cracks, hardening, discoloration, etc.) or displacement or damage caused by external forces. .
- If a slight leakage is found, check whether the bolts are loose first, and tighten the bolts appropriately if necessary; if the leakage is serious or the gasket is obviously aged or damaged, stop the machine in time and replace the gasket.
- During tank maintenance or long-term outage, clean and protect the gasket by applying an appropriate amount of protective grease to avoid exposure to harsh environments such as strong light, ozone, acid and alkali.
