PCI 3 Coating Systems
LoneStar Fastener's PCI 3 Coating Systems have for years provided
excellent make up/break out torque
characteristics and corrosion
resistance. PCI 3 has established
itself as the defacto standard
for corrosion protection in petro-chemical,
refining, pipelines, offshore
platforms and structures, and
other applications challenged
by a corrosive environment.
with our Fluoropolymer topcoat, the PCI 3 system with
zinc plate base coat, provides the abrasion, chemical
resistance, and lubricity required for a wide variety
of hydrocarbon production and processing applications
around the world.
The PCI 3 system has consistently proven itself to withstand over
2000 hours of salt fog exposure per ASTM B-117 requirements.
The secret to the success of LoneStar’s PCI 3 Plus
System lies in SermaGard, the ceramic metallic bonding matrix applied
as a basecoat. SermaGard provides superior corrosion resistance
in salt environments, especially splash zone areas, and with Whitford
Xylan Fluoropolymer top-coats provide the lubricity to achieve
maximum torque during make-up and break-out.
one test cycle, LoneStar PCI 3
bolts were exposed
to extreme Salt Fog
Testing while torqued
to 50% minimum yield
strength on a standard
6” flange. The
bolts were inspected
every 500 hours to
record potential failure
rates, and even after
4000 hours of extreme
stress, the bolts
coated with the SermaGard
Basecoat and our proven
topcoat showed no
evidence of red rust
or frozen nuts.
quality tests prove that
the PCI 3 systems provides:
- Protection from corrosion damage caused by handling
and mechanical installation.
- Excellent elongation properties that ensures integrity of the
coating during the tensioning process.
- Assurance of an extended fastener product life.
