Sponge-Jet Approvals and
Accolades
Acceptance and implementation of PAB is recommended
by the pipe
work group
PAB (Pliant Abrasive Blasting) or Sponge-Jet,
isidentified as an attractive alternative to
handtool and power tool cleaning.
Using pliant abrasive blasting versus power
tool cleaning increases coating life 200 to
700%.
Compared to garnet blasting, dust control
is simplified (no boxing in structures).
Intrinsic risk of eye injury is reduced
Work conditions in adjacent crafts/units
are improved
The net savings with pliant abrasive blasting
compared to hand-tooling for insulated piping
is 42.16% and 26.47% for non-insulated piping.
PAB will save even more by reducing replacment
and increased safety. We see a large amount
of steel replacment due to use of handtool
or power tool cleaning.
Pemex’s Department
of Norms and Specifications:
In the “Coating and Protective Systems
for Metals” specification report, the
Department of Norms and Specifications suggests
that "wherever
dust restrictions apply, use alternative methodsas Polyurethane foam with abrasive particles."
Technical Report
for Abrasive Blasting on Platform P-VI, Tank
TQ-34:
“An effective reduction of labor force
of 60% was confirmed in comparison to the other
abrasive processes… reduction of labor
force refers to the night shift responsible
for the disposal of residues.”
Using the Sponge-Jet
system enabled other trades to keep working
while blasting is being carried out.
Safety
and Environmental Control departments are very
impressed with no lost time accidents during
the shutdowns due to grit/foreign bodies getting
into people’s eyes.
The
speed of clean-up operations is dramatically
faster than grit blasting and the area is clean
enough for plant inspection to be carried out
immediately after blasting.
The
preferred method for most Engineers running
a shutdown.
