The designer can also use the software
to apply and test different surface-refining
sub-processes to choose
the optimal one (Figure 2). This not
only resulted in a quick transition into
the First-Article section of the project,
but it also created a standardized
framework to further ease setting up
future builds to meet IMI Critical's
specific surface finish and flow characteristic
requirements.
With API20S requirements always
in mind during the project, the automation
provided by the AM system's
internal quality-control software ensured
the collection of a large amount
of data about pre-build
calibration,
layer-by-layer build information, and
a final build report. The raw data and
height-mapper images were also useful
for evaluating and assessing critical
areas of the part for future production.
Finishing the Parts
The two First Article choke valve
components were printed at the Knust
Godwin facility (Figure 3a). From
there, the valves were removed from
the build plate along with test specimens.
The valves were then machined
to final finish (Figure 3b) and the
specimens were tested in accordance
with API20S, which showed compliance
to IMI Critical's materials specification.
The valves were then flow
tested at IMI Critical before being
delivered to the O&G operator for use
in upcoming field trials.
With initial testing and analysis
deemed successful, production builds
are ongoing, leveraging the manufacturing
plan established during the FirstArticle
build. Additional field testing is
also being performed to collect more
operational data. The result will be production-ready
components, adhering
to current API20S standards, that will
be put through real-world field trials at
one of the operator's sites.
