3. O-Rings
O-rings are perhaps one of the most widely used rubber components in the petrochemical industry. These simple, yet highly effective, sealing elements are used to create a tight seal between two surfaces, preventing the escape of fluids and gases. O-rings made from rubber raw materials are favored for their elasticity, resilience, and ability to maintain their shape under pressure.In the petrochemical industry, O-rings are used in a variety of equipment, including valves, pumps, and hydraulic systems. The selection of the appropriate rubber compound for O-rings is critical, as different compounds offer varying levels of resistance to chemicals, temperature, and wear. For example, fluorocarbon rubber (FKM) O-rings are often used in petrochemical applications due to their excellent resistance to high temperatures and aggressive chemicals.
The reliability of rubber O-rings is essential in ensuring the safe operation of petrochemical processes. A failed O-ring can lead to leaks, which in turn can cause equipment damage, production downtime, and safety hazards. Therefore, the quality and performance of rubber raw materials used in O-rings are of utmost importance in the petrochemical industry.
4. Vibration Dampening
