Garlock Flat Gasket

The Garlock Flat Gasket represents a paragon of high-performance non-metallic gaskets meticulously engineered to thrive in exacting industrial settings. Made from Garlock Gylon 3500, a composite material of PTFE and silica, it offers exceptional chemical resistance, thermal stability, and mechanical strength. Compliant with the ASME B16.47 B standard and available in a size of 32 Inches, the Garlock Flat Gasket is suitable for 150 LB pressure systems and effectively handles a wide range of complex fluid services, including strong acids, hydrocarbons, chlorine, and cryogenic media (such as liquefied natural gas). With its excellent corrosion resistance and durability, the Garlock Flat Gasket is an ideal choice for piping systems in the chemical, petrochemical, and energy sectors, ensuring long-term reliable sealing performance and system stability.  

In addition to its outstanding chemical and mechanical properties, the Garlock Flat Gasket also boasts exceptional electrical insulation performance, making it a perfect solution for applications that require electrical isolation and corrosion protection. 

1. Volume Resistivity: ≥ 10^18 Ω·cm  

Tested per the ASTM D257 standard, the Garlock Flat Gasket achieves a volume resistivity of ≥ 10^18 Ω·cm. This value indicates extremely low electrical conductivity, effectively blocking the passage of current. In industrial applications, this characteristic of the Garlock Flat Gasket significantly reduces the risk of galvanic corrosion, particularly in piping or equipment where different metals are in contact. Galvanic corrosion is a common cause of premature equipment failure. The high volume resistivity of the Garlock Flat Gasket offers dependable electrical isolation, thereby elongating the service life of the equipment. 

2. Dielectric Strength: ≥ 40 kV/mm  

Tested according to the ASTM D149 standard, the Garlock Flat Gasket achieves a dielectric strength of ≥ 40 kV/mm. Dielectric strength serves as a crucial metric of a material's capacity to resist electrical breakdown under high-voltage conditions. Whether in power transmission, high-voltage equipment sealing, or other applications requiring electrical isolation, the Garlock Flat Gasket provides reliable protection against electrical failures and potential safety hazards.  

Advantages  

Prevention of Galvanic Corrosion: The high-volume resistivity of the Garlock Flat Gasket effectively blocks current, reducing electrochemical reactions between different metals and extending equipment life.  

Safety in High-Voltage Environments: The high dielectric strength of the Garlock Flat Gasket ensures that the gasket remains impervious to break down under high-voltage conditions, safeguarding system stability.

Broad Applicability: Combining its excellent chemical and mechanical properties, the Garlock Flat Gasket is suitable for chemical, petrochemical, power, and other industrial environments requiring electrical isolation.  

With its exceptional electrical insulation performance, the Garlock Flat Gasket not only meets stringent sealing requirements but also provides additional electrical protection for industrial systems, making it a high-performance and safe gasket solution.

Whether deployed in corrosive media or high-voltage environments, this gasket consistently delivers reliable and efficient performance, solidifying its status as the premier choice in industrial sealing applications.
