NDE OFFERS A NEW PRESENTATION IN THE SERIES ON
ENGINEERING EXCELLENCE IN THE USE & BENEFITS OF STAINLESS STEEL
STAINLESS STEELS IN WATER APPLICATIONS
With over 60 years of experience in the supply and support of stainless steel materials to South African industry, NDE has consolidated their knowledge into a series of presentations, accredited by Consulting Engineers South Africa (CESA), on engineering excellence in the use and benefits of stainless steel.
STAINLESS STEELS IN WATER APPLICATIONS incorporates
- Different methods of desalination
- Water industry applications including
- mechanical systems – for biological, oxidation and pipe systems
- sludge treatment
- subsoil water technology
- Causes and types of corrosion, and how to avoid them
- Stainless steel cost and quality benefits
- An overview of some of the 150 grades of stainless steel, grouped into families
- Useful basic information and hands-on knowledge of applications
TÜV AUDIT AND RENEWAL OF
NDE’s ISO 9001 CERTIFICATION
NDE head office and branches across the country received a positive and complimentary assessment, with no non-conformances, from the TÜV Rheinland organisation. This was during the 2015 audit of NDE’s long-standing and valued ISO 9001 certification for quality management.
APPOINTED NDE DEPUTY MANAGING DIRECTOR
NDE has announced the appointment of Hardy Esterhuizen as Deputy Managing Director.
Mike Campbell continues as Managing Director.
Hardy retains his roles as manager of the Gauteng region - supported by Deputy, James Carmichael - and of overseeing NDE in KwaZulu-Natal.
Hardy Esterhuizen joined NDE Gauteng in 1998 as a Sales Representative and was appointed to head up the Gauteng region in 2006. He opened NDE’s Germiston branch in 2010 and the Pretoria branch in 2012.
Hardy’s formal appointment as Deputy Managing Director is part of NDE’s management succession plan which saw the appointment of Andries Schreuder as Manager of NDE Cape Town in 2014 and Llewellyn Dollman, Cape Town Manager since 1989, moving to a new role in procurement motivated by NDE’s growing need for a centralised purchasing function.
“I look forward to the interesting challenges and opportunities of switching from a regional to a national focus for NDE, knowing that day-to-day operations in Gauteng are in the hands of a very able management team,” says Hardy.
“It is business as usual preserving the status quo at NDE, retaining conservative management and staying open to new technological and market opportunities going forward,” he says.
“We celebrate the managers and leaders of the calibre of Hardy in our ranks, able to step forward in the natural progression of management development in our organisation,” says Mike Campbell.
NDE AND LIFE CYCLE COSTING (LCC)
Life Cycle Costing (LCC), a methodology for selecting the most cost-effective design and materials, incorporates future costs for maintenance, operation, replacement and downtime - which can often exceed upfront material costs if careful assessment of expected conditions and proposed
materials is not undertaken.
NDE’s technical team assists clients with this crucial step when selecting the appropriate stainless steel materials, based on engineering requirements, environmental and operating conditions as well as risk appraisal and prevailing commodity prices.
- First cost or Upfront cost
- Operational costs
- Replacement costs
- Value vs Risk
LCC AND BENEFITS OF STAINLESS STEEL REBAR
PROGRESO PIER MEXICO
This slide from NDE’s presentation Duplex LDX 2101 Stainless Steel in Structural Steel Applications graphically illustrates the benefits of LIFE CYCLE COSTING and THE USE OF STAINLESS STEEL REBAR.
|First pier built 1937-41 with nickel-containing stainless steel rebar still stands.||Second pier built 1960’s with carbon steel rebar, failed.|
According to the Progreso Port Authorities (1998) there has been no major repair work during its lifetime and a complete lack of routine maintenance activities.
“Progreso’s first pier remains in service and the full extent of the environmental, economic and social benefits of having selected nickel containing stainless steel continue to accumulate”

DID YOU KNOW?
CREVICE CORROSION is one of several types of corrosion which may occur in stainless steel under certain circumstances - and which can be prevented. It occurs in areas where crevices are formed:
• Between flanges
• Under bolt heads
• Under sediments on the bottom of tanks
• In/around badly designed joints
It can often be eliminated through design.
