Kammprofile gasket DIN 2697

Description

1. Product OverviewThe Kammprofile gasket DIN 2697 is a high-performance metallic sealing component featuring a solid metal core with concentric serrations on both surfaces, typically faced with soft sealing materials like flexible graphite or PTFE. It is primarily used in industrial piping systems, heat exchangers, valves, pumps, and vessels requiring reliable sealing under extreme pressure and temperature conditions. Its key value proposition lies in superior sealing efficiency, exceptional durability, and the ability to accommodate worn or lightweight flanges where traditional gaskets fail. Strategically, this gasket is critical for maintaining operational integrity in demanding industrial environments, reducing leak risks, and minimizing maintenance costs across global chemical, petrochemical, and energy sectors.

2. Key Specifications & Technical Characteristics

• Chemical composition/material components: Solid metal core (typically 304/304L or 316L stainless steel) with concentric serrations; soft sealing facing (flexible graphite, EPTFE, or PTFE)

• Purity level/grade: DIN 2697 compliant; metal core grades 304, 304L, 316L stainless steel; sealing materials meet industrial purity standards for chemical resistance

• Physical characteristics:

  • Form: Flat gasket with grooved/serrated metal core

  • Thickness: 3.00 mm (+0/-0.25 mm) or 4.00 mm (+0/-0.25 mm)

  • Cam pitch: Standard 1.5 mm

  • Density: High-density metallic core with compressible soft facing

  • Color: Metallic silver (core) with black/graphite or white/PTFE facing

• Packaging options: Protective plastic wrapping, cardboard boxes, or steel drums for bulk shipments; custom packaging available for enterprise orders

• Shelf life: 5+ years when stored in dry, temperature-controlled conditions away from direct sunlight and moisture

3. Core Industrial Applications

• Primary industries: Petrochemical, chemical processing, oil & gas, power generation, pharmaceutical, and marine industries

• Specific operational use cases:

  • Sealing flanges in high-pressure piping systems (PN10 to PN400 according to DIN 2697)

  • Heat exchanger sealing (especially for worn jacketed gasket designs)

  • Valve, pump, and vessel connections requiring full-vacuum to maximum flange pressure ratings

• Performance advantages over alternatives:

  • Compresses significantly while maintaining seal integrity under thermal cycling

  • Handles temperatures from cryogenic to 1090°C (2000°F), depending on sealing material

  • Superior to spiral-wound gaskets in worn flange applications and lightweight flange designs

  • Efficient sealing with lower bolt load requirements, reducing flange deformation risks
