Specifications of Spiral Wound Gaskets

A spiral wound gasket is a type of sealing gasket used to create a secure and reliable seal between two flange surfaces. It is widely used in industrial applications where there is a need to prevent leakage of fluids or gases under high-pressure and high-temperature conditions. The construction of a spiral wound gasket consists of several key components. Spiral wound gaskets are a type of sealing gasket commonly used in industrial applications. They are designed to provide a tight and reliable seal between two flange surfaces.

Here are the typical specifications of spiral wound gaskets:

Construction:

Spiral wound gaskets are composed of three main components:

·        Centering ring: A solid metal ring placed in the center of the gasket to provide structural support and facilitate alignment during installation.

·        Metal winding: Thin metal strip (usually stainless steel) wound in a V-shaped profile, forming the sealing element of the gasket.

·        Filler material: Soft material, often graphite or PTFE (polytetrafluoroethylene), is used to fill the spaces between the metal windings and provide enhanced sealing properties.

Materials:

·        Metal winding: Stainless steel is the most common material used for the metal winding due to its strength, corrosion resistance, and ability to withstand high temperatures. Other metals like carbon steel, Monel, and Inconel may be used depending on the application requirements.

·        Filler material: Graphite is commonly used as a filler material for its excellent chemical resistance and high-temperature capabilities. PTFE is also used when chemical compatibility is a concern.

Dimensions:

·        Inner diameter (ID): The inner diameter of the gasket corresponds to the size of the pipe or equipment flange it is intended to seal.

·        Outer diameter (OD): The outer diameter of the gasket is larger than the ID and is determined based on the flange size to ensure proper sealing.

·        Thickness: Spiral wound gaskets are available in various thicknesses, typically ranging from 1/8 inch (3.2 mm) to 3/8 inch (9.5 mm) or more.

Pressure and temperature ratings:

·       Spiral wound gaskets at Superlite Jointings are designed to withstand a wide range of pressures and temperatures. The pressure rating depends on factors such as the gasket material, winding density, and the type of flange being sealed.

·       Temperature ratings also vary based on the materials used. Graphite-filled gaskets can handle temperatures ranging from -200°C to 550°C (-330°F to 1020°F), while PTFE-filled gaskets offer higher temperature resistance, typically up to 260°C (500°F).

Applications:

·       Spiral wound gaskets are used in various industries, including oil and gas, petrochemical, power generation, chemical processing, and refining.

·       They are suitable for sealing flanges in high-pressure and high-temperature applications where a reliable and leak-free seal is required.

The specific spiral wound gasket specifications may vary depending on the industrial gasket manufacturer, application requirements, and industry standards. It is always recommended to consult the gasket manufacturing company's documentation or relevant standards for precise information regarding a particular gasket.

Manufacturing Process of Non Asbestos Gaskets

Image
The manufacturing process of non asbestos gaskets can vary depending on the specific types of gaskets and the materials being used. The manufacturing process of non-asbestos gaskets typically involves the following steps: Material selection Non-asbestos gaskets are made from a combination of synthetic fibers, fillers, and elastomers. The specific materials used may vary depending on the application and requirements of the gasket. Mixing The selected materials are mixed together in precise proportions. The mixing process ensures uniform distribution of the fibers and fillers throughout the mixture. Gasket Sheet formation The mixed material is then formed into sheets using a combination of heat, pressure, and sometimes extrusion. The sheets are typically formed to a specific thickness, width, and length. Cutting The gasket sheets are cut into the desired shape and size. This can be done using various methods such as die-cutting, water jet cutting, or laser cutting. The cu...

What is a Gasket: How does a Gasket function?

Image
An industrial gasket is a mechanical sealing device that is used to fill the gap or space between two or more mating surfaces. It is typically made of a compressible material, such as rubber, silicone, metal, or a combination of materials, and is designed to prevent leakage of fluids or gases under various operating conditions. The primary function of an industrial gasket is to create a reliable and durable seal between two surfaces, ensuring that there is no leakage or seepage of fluids or gases. When two surfaces are bolted or joined together, the gasket is placed between them. When the bolts or fasteners are tightened, the gasket is compressed, and it fills any irregularities or imperfections on the mating surfaces, creating a tight and secure seal. The compression of the gasket causes it to conform to the shape of the mating surfaces, effectively sealing the joint and preventing the escape or entry of fluids or gases. The choice of gasket material depends on the specific applic...

Best Gasket Material for Food Industry

Image
Gaskets are commonly used in the food industry to create a seal between two mating surfaces to prevent the leakage of fluids or contaminants. They are used in various food processing equipment such as pumps, valves, pipes, and tanks. The best gasket material for the food industry will depend on the specific application, temperature, pressure, and type of food being processed. However, some commonly used materials for food industry gaskets include: Silicone : Silicone industrial gaskets are a popular choice for the food industry because they are non-toxic, odorless, and can withstand high temperatures. They are also easy to clean and sanitize. EPDM (Ethylene Propylene Diene Monomer) : EPDM gaskets are a good choice for food processing applications that require resistance to high temperatures, steam, and chemicals. Nitrile : Nitrile gaskets are a good choice for food processing applications that require resistance to oils and fats. They are also resistant to high temperatures and...
