Professional development training course

Advanced elastomer technology and seal design for critical sealing applications
A two day professional development course

Introduction
This course comprises of the 1-day professional development course with the second day building on the theory. Delegates will undertake practical exercises including material property testing, material analysis, hardware design calculations and finite element analysis (FEA) methodology, to reinforce theory and bring practical significance to this topic.

Delegates will spend Day 2 carrying out various practical testing and analysis techniques in the PPE Materials Characterisation Centre and Application Engineering Department.

Course aim
This course will focuson real-life applications. Its aim is to ensure all participants acquire a fundamental understanding of elastomer sealing technology and performance relating to critical sealing applications. The course will include case studies with practical suggestions on implementing improvements to the delegates own applications.

Course objectives
At the end of the training session, delegates will be able to:

  • Explain how O-ring seals are manufactured.
  • Define the range of elastomers available and understand their inherent strengths and weaknesses.
  • Ask appropriate questions of elastomer manufacturers in order to compare and evaluate the suitability of elastomer materials.
  • Specify the optimum elastomer material for any given application.
  • Calculate optimum O-ring and seal sizes to fit existing hardware.
  • Design optimum new hardware for critical seal applications.
  • Combine the latest materials technology with modern design techniques to design a more competitive product.
  • Identify and diagnose potential sealing problems early thereby reducing any possible downtime.
  • Specify the causes of seal failure and take appropriate action to eliminate future occurrences and potential warranty claims .
  • Extend preventative maintenance (PM) cycles.
  • Estimate how differences in service environment may affect seal performance.
  • Understand how to achieve cost savings by informed seal material selection, avoiding over-specification.
  • Write a robust sealing specification.
  • Explain the effects of entropy and viscoleasticity with regard to elastomers.
  • Understand a wide variety of failure mechanisms and how they can be identified using the most modern analytical techniques.
  • Understand how different grades of materials are compounded, and how the different ingredients can affect a seals’
    performance.
  • Explain the mechanisms commonly used in an attempt to predict seal life; i.e. compression set, stress relaxation etc.
  • Review of the Arrhenius Equation, and how its application relates to sealing performance over time.
  • Demonstrate the effects of temperature on an elastomeric seal, both in terms of heat ageing as well as strength-attemperature.
  • Undertake practical tests related to chemical swell and interpret the results from incompatibility due to different
    solubility parameters.
  • Show the effects of cross-link density, and how this can be measured experimentally.
  • Understand the differences related to low-temperature performance of seals, both in terms of material selection and
    seal design.
  • Explain why back-up rings are required, why different materials are used, and how to successfully design seals using back-up rings.
  • Specify different seal geometries based upon application conditions, e.g. cap-seals, single or multiple back-up rings,
    T-seals etc.
  • Apply Newton’s Third Law to seal design.
  • Carry out finite element analysis (FEA), and a practical example of creating mathematical models using ANSYS®.

Who should attend?
This course is designed for:

  • Project and Design Engineers involved in seal design and/or seal specification
  • Quality Managers and Engineers
  • Technical Managers
  • Material Engineers
  • Engineering and Sealing Consultants

Personal impact
Attendance at the workshop will result in individuals developing their knowledge, understanding and skills in various aspects of elastomer technology, seal design and how this impacts on applications they are involved with. They will be able take this knowledge and apply it in their day-to-day activities to achieve cost savings, more robust designs and display to their own customers a greater depth of knowledge.

The seminar is based on a combination of interactive activities - group and individual exercises, case studies, hands-on problem solving tasks and discussions - along with formal technical input from the course trainers. Each delegate recieves a certificate of attendance and a course handbook which provides a valuable source of information for future reference.
