Whether your application requires sealing at low or high temperatures, these gaskets are up to the challenge. It caters to diverse industries, including oil and gas, chemical, petrochemical, and power generation, where varying temperatures and high pressures are the norm.
  • Chemical Compatibility: It exhibits remarkable resistance to many chemicals, making it an ideal choice for corrosive environments. The metal winding strip boasts excellent resistance to chemical attack, while the filler material acts as a crucial barrier, preventing fluid leakage and ensuring a secure seal.
  • Versatility: The gasket is highly adaptable and can be customized to meet specific application requirements. We offer various metal winding strip materials, including stainless steel, carbon steel, and specialized alloys. The filler material can also be tailored to your specific needs, with options such as graphite or PTFE, allowing for compatibility with multiple applications.
  • Easy Installation: The ingenious design of the spiral wound gasket makes installation swift and straightforward. It effortlessly compresses between two face flanges, creating a secure and dependable seal. While available in standard sizes, spiral gaskets can also be tailored to fit your unique requirements, ensuring a perfect fit.
  • Cost-Effective Solution: Spiral gasket offers remarkable value for your investment. Its extended service life, unwavering sealing performance, and resistance to temperature and pressure fluctuations significantly minimize downtime and maintenance costs. Opting for these gaskets is a cost-effective way to ensure reliable sealing for your industrial operations in the face of challenging temperatures and pressures.

Installation of Spiral Metallic Gaskets

Flange Condition

  • Remove the old gasket and ensure the flange faces are clean and free from indentations and scoring. Radial (cross-face) scoring is a particular concern and can lead to joint leakage
  • For spiral wound gaskets, a surface finish of 3.2um to 6.3pm Ra (125 to 250 micro inches) is recommended. Use a surface comparator to check flange finishes
  • Check that the flange faces are parallel or that the pipework is sufficiently flexible to pull the flanges parallel and concentric without excessive bolt loads.

Gasket

  • Always use a new gasket
  • Check that the gasket is in good condition and that the dimensions are correct for the class and size of the flanges
  • Do not use jointing compounds, grease, or lubricants with metallic gasket materials.
  • If there is a requirement to fix the gasket to the flange before assembly, then a light dusting of spray adhesive must be used.

Installation

  • Ensure that the gasket is installed centrally
  • It is recommended that the bolts be tightened using a controlled method such as torque or tension.
  • Finger tighten nuts. Make a final tightening sequence, working around the flange and tightening each bolt until the specified torque is achieved.
    After completion of installation, make sure that the flange faces are parallel.

FAQ's

A  Spiral wound gaskets are composed of a combination of metallic and filler substances. Typically, these spiral wound metallic gaskets consist of a metal component (usually enriched with carbon or made of stainless steel) wound in an outward circular spiral pattern (although different shapes are feasible). Simultaneously, the filler material (typically a pliable graphite) is wound in a similar fashion but originates from the opposite side. 

Spiral wound gaskets have established themselves as the most dependable sealing components suitable for challenging, vital, and demanding applications.  Spiral  gaskets offer excellent sealing performance, compatibility with various media, resilience to high temperatures and pressures, and the ability to compensate for flange irregularities, making them a reliable choice for demanding sealing applications. 

Choosing the right spiral wound gasket involves considering factors such as the flange design, pressure class, temperature and pressure requirements, material selection, dimensions, and compliance with standards. Consulting with a trusted spiral wound gasket manufacturer can help you make an informed decision.

A spiral wound gasket works by compressing a soft filler material between flange surfaces. The metallic winding strip provides support, while the filler material fills gaps and compensates for surface irregularities, creating a reliable seal. The gasket’s flexibility accommodates movements and thermal changes, ensuring a tight seal in high-pressure and high-temperature applications.
