ASME b16.21 non metallic gasket manufacturer in India

Trusted non metallic flat ring gasket supplier in India

What types of non metallic gasket are covered under ASME B16.21?

• Non-Metallic flat gaskets are flat in shape and their functionality lies in sealing between flange faces.
• A spiral wound non-metallic gasket is made of a combination of metal and non-metallic filler materials.
• Ring gaskets made of non-metals are shaped like a circle with a hole in the middle. These are frequently made of rubber, although they can also be formed of elastomers and other materials. When a circular sealing surface is required, these gaskets are employed. In flanged pipe couplings, for example.
• Filler materials are used in non-metallic jacketed gaskets, which are used to seal spaces inside metallic jackets. The filler material is supported structurally and kept safe by the jacket.

What is the maximum operating temperature for ASME b16.21 non metallic flat gasket according to ASME B16.21?

• Although ASME B16.21 does not specify a maximum working temperature, there are variables that can be used to estimate it. Non-metallic gaskets have temperature restrictions based on the materials used in their production.
• Without the gasket, different types of non-metallic materials have distinct temperature ranges where good sealing occurs.
• When selecting an ASME b16.21 non metallic flat gasket, it is wise to consult the manufacturer's recommendations, relevant industry standards and specifications. These typically provide information on the maximum operating temperature for specific gasket materials.

What are the advantages of using non metallic flat ring gasket over metallic gaskets?

• A non metallic flat ring gasket offers excellent resistance to various chemicals. This makes them suitable for applications involving corrosive fluids or environments.
• The electrically insulating gaskets benefit applications where electrical conductivity needs to be avoided or isolated.
• These are generally more cost-effective than metal gaskets.
• The gaskets are lighter compared to metal gaskets.
• Being softer and more flexible than metallic gaskets allows them to conform to irregularities in flange surfaces, while still providing improved sealing.
• These gaskets can help prevent galvanic corrosion by acting as a barrier between dissimilar metals in a flange connection.

Can non metallic spiral wound gasket be used in applications that involve high pressure and temperature?

• No, it is not usually advised to use a non-metallic spiral wound gasket in high-pressure and high-temperature applications. For applications involving low pressure and low temperature, it is typically selected.
• It works best for sealing tasks involving non-corrosive gases and fluids.
• The use of non-metal gaskets, such as spiral wrapped metal gaskets or ring joint gaskets, is chosen for applications where high temperature or high pressure are guaranteed.
• Metallic gaskets offer better sealing performance, higher pressure ratings, and superior temperature resistance compared to non-metallic ones. They can withstand challenging operating conditions.

What factors should be considered when selecting an ASME b 16.21-non-metallic gasket material?

• Calculate the necessary pressure, temperature, and maximum and minimum temperatures.
• Select a gasket material that can withstand the media's chemical composition. Take into account the fluid's kind (liquid or gas). It shouldn't harm the gasket material at all.
• The ASME b 16.21-non-metallic gaskets must tolerate environmental factors without deterioration or performance loss.
• Make sure the material for the gasket is appropriate for the particular requirements of the application and capable of offering a solid seal.

How can the thickness of a non metallic gasket sheet affect its sealing performance?

• The thickness of the non metallic gasket sheet determines the amount of compression it undergoes when the flanges are tightened. A thicker gasket sheet requires more compression to achieve an effective seal.
• It may require higher bolt loads to achieve the necessary compression, ensuring proper sealing. The proper stress distribution is essential.
• These gaskets can generate higher sealing pressures, which can be advantageous in certain applications, but not all.
• Thicker gasket sheets may exhibit better resistance to creep relaxation, enhancing seal longevity.
• These can compensate for rougher or less flat flange surfaces by filling in gaps and irregularities.
