1. INTRODUCTION

Non-destructive testing (NDT),
Non-destructive examination (NDE),
Non-destructive inspection (NDI):
Family of specialized technical
inspection methods which provide
information about the condition of
materials and components without
destroying them
The term (NDT) is generally applied to
non - medical investigations of material integrity.




NDT examines actual production pieces and
 reveals the presence of flaws which can be
 evaluated against accept / reject criteria
NDT Applications

NDT is used in a variety of
settings that covers a
wide range of industrial
activity:
 Automotive
    Engine parts

    Frame




   Aviation / Aerospace
      Airframes

      Power plants Space frames

      Jet engines

        • Rocketry
   Construction             Petrochemical
      Structures               Pipelines


      Bridges                  Storage tanks




   Manufacturing            Miscellaneous
     Machine parts            Amusement park rides




   Nuclear engineering
      Pressure vessels
Modern nondestructive tests are used by
 manufacturers to:

   Ensure product integrity, and in turn, reliability
   Avoid failures, prevent accidents and save
    human life
   Make a profit for the user
   Ensure customer satisfaction and maintain the
    manufacturer's reputation
   Aid in better product design
   Control manufacturing processes
   Lower manufacturing costs
   Maintain uniform quality level
   Ensure operational readiness
NDT Methods
 There are several established NDT methods
  currently in industrial use.
 New methods are being constantly researched
  and developed, and many of the established
  ones have their effectiveness and efficiency
  enhanced by conversion to electronic,
  computerized, or robotic operation.
 Five   basic methods:
   Liquid Penetrant Testing (PT)
   Magnetic Particle Testing (MT)
   Radiographic Testing (RT)
   Ultrasonic Testing (UT)
   Eddy Current Testing (ET).
    2.0 CHALLENGES AND ISSUES
   Establishment of clear national policies and
    regulations
   Acceptance by decision-makers;
    integration into national science system
   Technology transfer mechanisms
   Relevance and appropriateness of
    technologies
   Quality management and control
   New management approach and
    management skills
 Organizational transformation
 Market intelligence; keeping  up to date
  with scientific / technological changes
 Clear programme plans and business
  plans with quantified objectives
 Confidence building
 Communication; sharing of information
 Satisfaction of needs and interests of all
  stakeholders
 Establishment of alliances
   Relationship between research,
    development and commercial activities
   Ethics in all activities
   Maintained credibility
   Weak manufacturing facilities
   Weak standard and safe infrastructure
   Engineering and technical education
    without NDT content
   Technical personnel lacks necessary
    skills
 3.0   INDICATORS OF SUSTAINABILITY FOR
       NDT FACILITIES


1)   Legal Sustainability
2)   Institutional Sustainability
3)   Sustainable Physical Facilities
4)   Sustainable Financial Resources
5)   Sustainable Human Resources
   4.0   OPPORTUNITIES

 The issues and challenges could be best
 interpreted as opportunities for ensuring safe
 engineering components and systems, and
 hence, a sustainable development.

Such opportunities include:
 NDT education and research,
 training and certification
 sales and services of NDT equipment, devices
  and consumables
                      and handling of
 Transportation, storage
 NDT equipment and accessories

 Production ofqualified and certified
 personnel that would be gainfully
 engaged in the various related
 economic activities.
5.0 CONCLUSION
Nigeria needs a vibrant oil, gas and other
  industrial sectors anchored on sound, home-
  grown, human and technological initiatives,
Nigerian Content Development :
NOT limited to ‘BUILDING CAPACITY’
BUT create
‘opportunities for Nigerians’
and thus enhance sustainable
development for economic self reliance
