In the harsh environments of oil extraction and transportation, the reliability of sealing performance is directly related to production safety, efficiency, and environmental responsibility. The Mascot Dual-Spring U-Cup Seal, with its innovative structure and high-quality materials, provides a multi-faceted sealing solution for the petroleum industry, making it a practical choice for high-pressure, high-temperature, and strong-corrosion environments.
Core Technology: A Scientific Combination of Materials and Structure
The Mascot Dual-Spring U-Cup Seal adopts a composite structure of polytetrafluoroethylene (PTFE) + high-strength springs, achieving double protection for sealing performance:
PTFE Base Material: It has good chemical resistance and high-temperature resistance, capable of withstanding corrosive media such as H₂S and CO₂ commonly found in oil and gas fields. It maintains stable physical properties within the range of -20℃ to 260℃, ensuring sealing integrity in extreme environments.
Dual-Spring Design: It uses 316L stainless steel springs (with optional customized materials) to provide continuous and stable preload, compensating for seal face wear and pressure fluctuations. Even under high pressure of 35MPa, it can maintain a zero-leakage state, with dynamic leakage strictly controlled at ≤0.01mL/min (in line with GB/T 2879-2025 standards).
Multi-Scenario Adaptability: Covering Core Sealing Needs of the Petroleum Industry
The Mascot Dual-Spring U-Cup Seal is suitable for the entire chain of sealing scenarios in the petroleum industry, providing support for multiple key links:
Oil Well Sealing: In extreme working conditions such as 3000-meter deep wells, it can maintain zero leakage for 500 consecutive days (referring to application data from Bohai Oilfield), effectively preventing oil and gas leakage and ensuring the safety of mining operations.
Pipeline Sealing: For oil and gas pipeline joints, it resists medium erosion and temperature changes, reducing environmental pollution and energy waste caused by leakage.
Equipment Sealing: It is suitable for key equipment such as rotating parts of drilling platforms and fracturing pumps. According to actual measurements by Sany Petroleum Equipment, the use of the dual-spring structure has extended the equipment maintenance cycle by 300%, helping to reduce operation and maintenance costs.
Performance Features: Demonstrating Sealing Reliability
The Mascot Dual-Spring U-Cup Seal, with its three core features, has become an optional solution for sealing upgrades in the petroleum industry:
High-Pressure Sealing Performance: Under the working condition of 150℃/35MPa, the PTFE + 316L spring combination can achieve a service life of 8000 hours, which is better than the durability standard of traditional seals.
Wide Medium Compatibility: Certified by ISO 23936-2 standards, it maintains stable performance in the full range of pH 1-14 media, meeting the needs of special scenarios such as sour oil and gas wells (API 6A-2024 standards).
Dynamic Adaptability: The dual-spring structure can real-time compensate for the deformation of the seal face, maintaining close fit even under dynamic working conditions such as equipment vibration and sudden pressure changes, reducing the risk of "micro-leakage".
