Features
Adjustment function:
To make the fit between components tighter and more accurate, ensuring the normal operation of the equipment.
Buffer and shock absorption effect:
In some equipment with vibration or impact, gaskets can play a buffering role, reduce noise, and extend the service life of the equipment
Sealing function:
The gasket can fill the small gaps between the connecting parts, prevent the leakage of liquids, gases and other media, and ensure the sealing and integrity of the system.
Protective function:
The gasket can isolate two components that are in contact with each other, avoiding problems such as wear and corrosion caused by direct contact between them
Materials
Stainless Steel:
Known for its corrosion resistance and ability to withstand high temperatures. Ideal for chemical processing, food and beverage, and marine applications.
01
Inconel:
Known for high-temperature strength and resistance to corrosion and oxidation, prevalent in aerospace and gas turbine engines.
02
Monel:
Excels in corrosive environments like marine and acidic settings, offering impressive mechanical strength for high-pressure applications.
03
Hastelloy:
Resists a wide range of corrosive chemicals, making it a top choice for chemical processing and petrochemical industries.
04
Type
Spiral Wound Gaskets (SWG)
Made with an alternating combination of a preformed engineered metal strip and a more compressible filler material, these gaskets create an excellent seal when compressed.
Kammprofile Gaskets
Also known as grooved metal gaskets, Kammprofile gaskets are highly prized for their durability in demanding applications such as heat exchangers.
Corrugated Flexible Graphite Gaskets (CFG)
Designed for severe service conditions, CFG gaskets are ideal for the refining, chemical, petrochemical, and pulp and paper industries. They consist of flexible graphite laminated with an adhesive bond on both sides of a corrugated 316 stainless steel core.
Ring Joint Gaskets (RTJ)
Metallic gaskets, or Ring Type Joint (RTJ) Gaskets, are forged or cast from solid metal and designed for high-pressure and high-temperature services.
Applications
Oil and Gas Industry: Used in pipelines, valves, and flange connections (including ASME B16.5 and API 6A).
Chemical Processing: Ideal for reactors, piping systems, and towers handling corrosive substances, requiring superior leak-free performance.
Power Generation & Steam: Often utilized in power plants for steam lines, turbines, and boiler systems due to high thermal resistance.
Refining & Petrochemical: Essential for heat exchangers, vessels, and reactors suffering from high thermal cycling and pressure fluctuations.
Marine & Shipbuilding: Employed in ship engines, heavy-duty piping, and ballast systems to manage extreme temperature swings and seawater corrosion.
Industrial Machinery: Used in pumps, valves, and compressors needing a balance of compressibility and structural integrity.
