In the refinery and petrochemical industry, selecting the right sealing solutions is vital for operational efficiency, safety, and maintenance cost reduction. Double Jacket Gaskets play a critical role in ensuring reliable sealing under high pressures, extreme temperatures, and corrosive chemicals. At Ningbo Kaxite Sealing Materials Co., Ltd., we produce high-quality Double Jacket Gaskets engineered to meet international standards and deliver long-term performance. In this article, we will explore key factors in selecting the right Double Jacket Gasket, provide detailed specifications, practical guidelines, and demonstrate why our products stand out in the industry.
A Double Jacket Gasket consists of two concentric metal jackets filled with a soft, high-performance sealing material. This structure allows the gasket to withstand extreme operating conditions while maintaining a reliable seal. Understanding its construction and functionality is essential when selecting the right gasket for refinery and petrochemical applications.

Q1: What factors should I consider when selecting a Double Jacket Gasket for high-pressure systems?
A1: Consider jacket material strength, filler density, flange compatibility, and temperature tolerance. Our Double Jacket Gaskets withstand pressures up to 5000 psi and provide stable sealing under thermal and mechanical stress.
Q2: How do different filler materials affect gasket performance?
A2: Filler materials affect compressibility, chemical resistance, and temperature tolerance. Flexible graphite provides high-temperature resistance and chemical stability, while PTFE suits non-corrosive moderate-temperature applications. Our factory provides material selection guidance based on system requirements.
Q3: Can a Double Jacket Gasket be used in corrosive chemical environments?
A3: Yes, with compatible jackets like 316 stainless steel and fillers such as flexible graphite, Double Jacket Gaskets resist aggressive chemicals. Our team ensures gaskets meet corrosion resistance standards for refinery and petrochemical systems.
Q4: How important is dimensional accuracy in gasket installation?
A4: Dimensional accuracy is critical to prevent leaks and maintain seal integrity. Our factory uses precise CNC cutting and automated measurement systems to ensure every gasket fits perfectly with its corresponding flange.
Q5: What maintenance practices help extend the life of Double Jacket Gaskets?
A5: Regular inspection, proper flange torque, and avoiding exposure beyond rated chemical or temperature limits extend gasket life. Our factory provides guidelines to ensure optimal installation and long-term performance.
