Metal Gasket

Metal gaskets play a pivotal role in ensuring leak-free connections, even in the most demanding environments. Their robust construction, coupled with superior sealing capabilities, makes them a preferred choice for industries ranging from oil and gas to chemical processing and automotive. At Asian Sealing Products, we offer a diverse range of metal gaskets that cater to the unique requirements of each industry.

At Asian Sealing Products, we offer a diverse portfolio of high-performance metal gaskets, each engineered to excel in specific industrial applications. Here’s a closer look at our most sought-after gasket types:

1. Spiral Wound Gaskets

Spiral wound gaskets are engineered with a unique construction: a V-shaped metal winding strip (typically stainless steel) interlayered with a soft, compressible filler material like graphite or PTFE. This design provides exceptional resilience and the ability to “spring back” (recovery) under varying pressure and temperature, ensuring a tight, leak-free seal.

• Key Features:
  • Excellent resilience and recovery
  • Adaptable to fluctuating pressure and temperature
  • Wide range of material compatibility
• Benefits:
  • Maintains seal integrity under dynamic conditions
  • High thermal stability
  • Broad chemical resistance
  • Can be cost-effective in some applications due to reusability
• Applications:
  • Ideal for heat exchangers, where temperature and pressure cycles are common.
  • Widely used in flanged pipe connections across various industries.
  • Suitable for process piping in chemical, petrochemical, and refining.
• Standards: Adheres to industry standards such as ASME B16.20 and API 601.
• Materials:
  • Winding Strips: SS 304, SS 316, Inconel, Monel
  • Filler: Graphite, PTFE

2. Ring Type Joint (RTJ) Gaskets: 

Ring Type Joint (RTJ) gaskets are precision-engineered, solid metal rings designed to create a robust, metal-to-metal seal. They are specifically designed for extreme high-pressure and high-temperature environments where other gasket types may fail.

• Key Features:
  • Metal-to-metal sealing
  • Designed for very high bolt loads
  • Compact and durable
• Benefits:
  • Provides an exceptionally tight and reliable seal
  • Withstands extreme pressure and temperature
  • High resistance to vibration and shock
• Applications:
  • Essential for critical applications in the oil & gas industry, including wellheads and pipelines.
  • Used in high-pressure valves and pressure vessels.
• Types: R, RX, and BX, each with a specific profile for different flange designs.
• Standards: Complies with API 6A and ASME B16.20 standards.
• Materials: Soft Iron, Low Carbon Steel, Stainless Steel, Inconel, Monel

3. Kammprofile Gaskets: 

Kammprofile gaskets feature a solid metal core with concentric serrated grooves (Kammprofile), faced on both sides with a soft sealing material. This design provides a combination of metal-to-metal contact for strength and soft material for effective sealing.

• Key Features:
  • Solid metal core with serrated grooves
  • Soft facing layers
  • High mechanical strength
• Benefits:
  • Excellent sealing performance
  • Requires lower bolt loads compared to RTJs
  • Highly reusable
  • Handles high temperatures and pressures
• Applications:
  • Ideal for heat exchangers, including those with narrow flanges.
  • Used in applications with high-temperature and pressure cycling.
  • Suitable for manways and boiler covers.
• Materials:
  • Core: SS 316, SS 304, Carbon Steel
  • Facing: Graphite, PTFE, Mica

4. Corrugated Metal Gaskets (CMG):

Corrugated metal gaskets (CMGs) consist of a corrugated metal core covered with a soft sealing layer. The corrugations enhance the gasket’s compressibility and recovery, making them a good choice for applications with less-than-ideal flange conditions.

• Key Features:
  • Corrugated metal core
  • Soft sealing layers
  • Good compressibility
• Benefits:
  • Provides a reliable seal, even with some flange irregularities
  • Good recovery
  • Cost-effective sealing solution
  • Handles moderate to high temperatures
• Applications:
  • Used in heat exchangers.
  • Suitable for compressors.
  • Applied in exhaust systems.
• Materials:
  • Core: Stainless Steel, Copper, Monel, Inconel
  • Facing: Graphite, PTFE

5. Metal Jacketed Gaskets: 

Metal jacketed gaskets consist of a soft filler material enclosed within a metal jacket. The metal jacket provides strength and protects the filler, while the soft filler ensures a good seal.

• Key Features:
  • Soft filler encased in a metal jacket
  • Variety of jacket styles
• Benefits:
  • Provides a reliable seal for moderate conditions
  • Protects the filler material
  • Cost-effective for many applications
• Applications:
  • Commonly used in heat exchangers.
  • Suitable for pumps, valves, and reactors.
  • Used in pipe flanges.
• Types: Single-jacketed, double-jacketed, and French style, each offering different sealing characteristics.
• Materials:
  • Jacket: SS 304, SS 316, Copper, Inconel, Monel
  • Filler: Graphite, Mica, Ceramic, Asbestos-free options

The Harmonized System (HS) Code is a standardized global system for classifying traded products. Metal gaskets are classified under HS Code 8484, which covers gaskets and similar joints made of metal sheeting, combined with other materials, or composed of two or more metal layers. This classification ensures efficient and accurate trade transactions.

Metal gaskets adhere to standards set by organizations to ensure uniformity, reliability, and consistent performance. Key standards include:

• ASME Standards: For example, ASME B16.20 for spiral wound gaskets in flanged connections.
• API Standards: Such as API 6A for wellhead and Christmas tree equipment, including ring joint gaskets.
• DIN Standards: For example, DIN 2696 for metal gaskets with flexible graphite fillers.
• ISO Standards: Including ISO 9001 for quality management systems.
• ASTM Standards: Such as ASTM F104 for non-metallic flat gaskets.
• EN Standards: Including EN 1514 for gasket dimensions and tolerances for compatibility with European flange norms.
