gasket specification

What are gaskets, and what are their functions?

  • Gaskets are mechanical components used in various industries to create a sealing barrier between two or more mating surfaces and prevent leakage of gases or fluids.
  • Gaskets fill the irregularities and imperfections in the mating surfaces, ensuring a reliable and leak-free connection.
  • Through their compressible design, they create a uniform sealing pressure.
  • These provide a cushioning effect, reducing the stress concentration and preventing damage or deformation of the surfaces due to excessive forces.
  • They act as a cushion, reducing the transmission of vibrations and preventing damage to the components.

What are the types of ASME B16.20 gaskets available in the stock?

  • The common types of ASME B16.20 gaskets are:
  • Spiral wound gaskets: Made of winding metal and filler material in a spiral pattern.
  • Ring Joint Gaskets (RTJ): Have a metallic ring with a hexagonal or octagonal cross-section.
  • Double Jacketed Gaskets: Consist of a soft filler material enclosed within two metal jackets.
  • Metal Jacketed Gaskets: Offer a combination of strength and sealing properties.
  • Kammprofile Gaskets: Have a solid metal core with serrated or concentric grooves on the sealing surface.
  • Corrugated Metal Gaskets: Made of thin metal layers formed into corrugations.
  • Lens Ring Gaskets: Have a convex shape and are typically used in applications that prioritize high compressive forces.

How to select the appropriate Steel gasket for a specific application?

  • Assess the temperature, pressure, and media involved in the application. Choose a steel gasket that can withstand the anticipated operating conditions without compromising its sealing capabilities.
  • Determine the type of flange being used as a gasket only suits a specific flange configuration.
  • The gasket material needs to be compatible with the media being conveyed, such as chemicals, gases, or fluids.
  • Select the most appropriate type (RTJ, spiral wound, etc.) based on requirements
  • The gasket must be compliant with the relevant industry standards and specifications.

What is the difference between a Stainless Steel gasket and a seal?

  • A stainless steel gasket is a specific type of gasket made entirely or predominantly of stainless steel material. These are commonly used in applications that require high temperature, pressure, or chemical resistance. Some of the functions are: providing a reliable seal between two mating surfaces, preventing leaks and maintaining the integrity of the system.
  • A seal prevents leakage or contains fluids within a system. Available in different forms like O-rings, gaskets, and more, a seal can be made of rubber, elastomers, metals, etc. It falls under a broader category.

What are the different materials used to manufacture ASME B16.21 Rubber Gasket?

  • Nitrile Rubber (NBR) is frequently used with fluids made of petroleum because it can endure a wide variety of temperatures.
  • One of the popular ASME B16.21 rubber gasket alternatives, neoprene rubber offers good resistance to corrosion, ozone, and chemicals.
  • An EPDM gasket has good resistance to ageing, UV rays, and weathering.
  • Silicone Rubber: A silicone gasket is flexible and resistant to high temperatures over a broad temperature range.
  • A fluoroelastomer with remarkable resistance to chemicals, lubricants, fuels, and high temperatures is Viton® Rubber.
  • It is well known that graphite gaskets have exceptional heat and chemical resistance.

How to install and remove an Industrial gasket safely?

  • Remove any debris from the flange surface by cleaning it. Before installation, inspect the industrial gasket for any obvious flaws or damage.
  • Based on application criteria including temperature, pressure, and chemical compatibility, choose the right gasket material.
  • Verify that the gasket is in the proper location, and the bolt holes are straight.
  • Applying the recommended torque values, gradually and evenly tighten the bolts or stud assemblies in a crisscross pattern.
  • Consider safety measures such as system depressurization, worker protection, etc. when removing a gasket.
  • Avoid making unexpected movements as you progressively loosen the bolts or stud assembly. After that, carefully remove the gasket.
