March — How is gasket stress defined in industry? December — What is the best wear face material for my mechanical seal? Even so, these gaskets have found a niche in industry. January — Extending mechanical seal life — how can their reliability be improved? August — Where mechanical seals meet pumps: What is the next generation? Part One April — How can the capabilities of primary seal materials be improved?
A surface that is not machined flat can provide leak paths. Is previous experience required? Part One April — How can the capabilities of primary seal materials be improved? Duration of the effects of low temperature exposure is not significant and the original properties are regained upon resumption of moderate temperatures; not before seal failure has most likely occurred.
January — What is the best silicon carbide wear face material for my mechanical seal? October — What are the symptoms, causes and corrective actions for failure of mechanical seals induced by chemical attack? A common improvement is an outer guiding ring. January — Why do I need to complete an application questionnaire? October — What gasket thickness should I use in my pump system?

Changes due to the prolonged exposure are chemical in nature, rather than physical, and are not reversible. Spiral wound gaskets are also used in high pressure pipelines and are made with stainless steel outer and inner rings and a center filled with spirally wound stainless steel tape wound together with graphite and PTFEformed in V shape.
When the gasket is thinner and smaller there will be a greater loss of torque. What standards are referenced in the course? Once you have completed the course, you will be asked a series of questions to check your knowledge and understanding.
Theoretically when the flanges are pressed, the sealing surfaces are absolutely parallel, in Introduction to Seals and Gaskets Engineering book however, the centerline of a pipeline cannot be absolutely concentric, and tightening the bolts on the flange moment makes the flange a discontinuity.
They work best with low speeds and low pressure differentials. Duration of the effects of low temperature exposure is not significant and the original properties are Introduction to Seals and Gaskets Engineering book upon resumption of moderate temperatures; not before seal failure has most likely occurred.
It contains many tables and drawings and provides in-depth information on mechanical seals designs and types, seal selection and seal material selection guides, suggested performance criteria, installation information, troubleshooting procedures, seal safety, as well as additional articles for reference.
These gaskets have proven to be reliable in most applications, and allow lower clamping forces than solid gaskets, albeit with a higher cost. December — What is the best wear face material for my mechanical seal? Identify the types of materials commonly used to make seal hardware.
Low durometer materials are used for low pressure applications, whereas high pressure may require a combination and specialized design. The filler is pumped between the shell and piece. Constant seating stress gaskets derive their name from the fact that the carrier ring profile takes flange rotation deflection under bolt preload into consideration.
This must be coupled with the judicious selection of a gasket material compatible with the mating surfaces. Third, the density of bolt arrangement has an obvious impact on the pressure distribution, the closer the bolts, the more uniform the pressure.

Double-jacketed gaskets[ edit ] Double-jacketed gaskets are another combination of filler material and metallic materials. October — What is the sealing technology of choice for water and wastewater treatment?
In general longer bolts and smaller diameters of bolt are better at preventing the loss of torque. Since generally the graphite will fail instead of the metal core, Kammprofile can be repaired during later inactivity.
The males develop a large almost trunk-like inflatable nose and look very different than the females … thus the name "elephant" seal. Service life is often a balance between the other environmental conditions that the seal must be exposed to.
