Product
&
Failure
Analysis.
A
key
to
permanently
solving
any

root
cause(s)
of
past
failure
modes
of
products
removed
from
service.
Hose
Master’s
in-house
product
and
failure
analysis
lab
can
identify
various
failure
modes,
whether
a
result
of
fatigue,
corrosion,
deformation,
or
from
a
host
of
other
possible
causes.

Expansion
Joint
Rebuild.
Using
customer-provided
components
from
an
expansion
joint
removed
from
service,
Hose
Master
can
replace
bellows
and
often
reuse
pre-existing
pipe
and
fittings.
This
offers
a
cost-effective
option
when
dealing
with
very
large
diameter
expansion
joints
and
special
designs.
Hose
Master
can
also
reverse-
engineer
the
product
for
its
specified
application
or
evaluate
the
parts
that
are
being
replaced
in
our
laboratory
to
determine
the
cause
of
failure.
Backed
with
this
knowledge,
Hose
Master’s
team
of
engineers
and
ASME
IX
certified
welders
can
design
and
make
any
necessary
changes
to
the
expansion
joint
to
enhance
its
performance
and
extend
its
service
life.
