It is always easier and cheaper to erase lines on a drawing than to
repair or replace failed components.
NACE certified Corrosion Specialist providing
professional corrosion services including: corrosion design review, corrosion consulting, cathodic
protection design, in-house training, online and distance learning
corrosion courses, corrosion diagnosis,
failure analysis, corrosion expert witness in litigation and arbitration cases
related to corrosion, materials, metallurgy, paints & metallic coatings.
WebCorr provides the following document preparation,

Material Selection Summary Table (MSST).
Third-party review of designs, drawings and technical specifications to
identify potential corrosion risks, the compatibility of materials,
the forms of corrosion and their mitigation.
of design and specifications on materials, processes, cathodic
protection and coatings to
identify potential corrosion failures and any clauses in the
specification that may lead to potential dispute, arbitration or
litigation among the parties involved. Corrosion liability can be
avoided through proper specifications.
Independent 3rd party
verification/validation of modeled/predicted corrosion growth rates.
In CO2 corrosion modeling, there is no such thing that one model
fits all pipeline conditions. It is simply wrong for a
contractor/consultant to use one (1) modeling software for all
clients and all pipeline conditions. At WebCorr, our NACE certified
Corrosion Specialist will validate your modeled/predicted corrosion
growth rates using properly selected models, laboratory test results
and field data in the literature. Our verification/validation report
will come complete with all supporting data and reference documents.
If necessary, we can train your engineers on CO2 modeling. Click the link below to see details on our 5-day training course on CO2
CO2 Corrosion Modeling for the Prediction of Internal Corrosion in
Oil Gas Pipelines
Third-party review of contracts to identify potential corrosion liabilities
and advices on how to deal with them
review of test reports and interpretations of test results
Technical bid evaluation support
Analysis of raw data from corrosion tests (both DC polarizations &
impedance measurements) and interpretation of corrosion test results
Expert witness and support in litigation and arbitration
matters related to corrosion, materials, metallurgy, paints & metallic coatings including thermal spray metallizing, galvanizing,
anodizing, chromating, phosphating, electroplating, electroless
plating, mechanical plating, and sheradizing or diffusion coating.

Subject: Seeking for Independent Review
We need your independent review on the topics shown below. Pls take a
look at it and justify on how soon you can give us the review in
writing. Also pls let us know what are the charges for this review. If
you need further information to justify any thing, pls let me know. I'll
also send you the thesis extract later on since i'm still preparing some
extract of it. However, i've also attached a part of it in the word
A. We need your professional view on the following:
(1). Deposition of scale is expected to occur after
only about 200 to 400 hours of chiller operation.
(2). Hence, based on 12 hours daily operation 365 days
per year, we can work
out that the
BEST PRACTICE to do manual cleaning is 22 times/year.
B. For Anodic Corrosion Effect in condenser tubes. We need your
view on the following (please refer to my powerpoint slides
(1). How serious is Anodic Corrosion effect on the normal
operation of the condenser tubes?
(2). For heat exchanger / condenser tubes maintenance, what
do you think
is the best method
/ strategy in preventing fouling and scaling?
(3). Our company has developed an automated heat exchanger
for the prevention of
fouling and scaling. You can check out our website
to have a basic understanding of the system. We need your
independent review of our
system as compared to systems available in the market. If you need further
information to justify, please let us know.
C. The normal life of industrial chiller is quoted to be around 15-20
referenced to the following materials [removed].
How reasonable is this statement in the context of local and overseas environments?
Thanks. Best Regards,

Subject: Design Consultancy Enquiry
Date: Wed, 8 Sep 2004 18:09:06 +0200
we are interested in contracting your services for an independent design
consultancy review for two industrial shell and tube heat exchangers (AET
type). These shell and tube heat exchangers are being supplied by our
Company, [name removed] (Engineering
Contractor Company), and the final Client is [company
In order to give you a brief idea, the materials in question are:
- Tubesheets: Carbon Steel titanium cladded from the tube side process
and bundle cage in SS 316 L ( SS 316 L baffles, tie rods ,spacers,
sealing strips and bundle runners instead of carbon steel ).
- Tubes: Ti
- Baffle plates: SS316 L
- Process shell side fluid: Hydrogen (Wet Sour/HIC Service)
- Tube side fluid: Sea Water
- Shell Material: KCS HIC Resistant (Full details such as datasheets,
specifications and drawings will be provided later).
The consultancy would consist of a design review of this equipment with
particular regard to material choice for tubes, baffles and tubesheets
with respect to the possibility of galvanic corrosion and/or hydrogen
embrittlemet cracking between tubes, baffles and tubesheet materials
owing to the design conditions and process fluids. We would appreciate
it if you could provide us with a quotation and/or indicate your
standard rates for this type of consultancy including the delivery date
for your final technical report.
We look forward to hearing from you.
