PSI ElectroStop™
Monolithic Isolation
Pipeline Fittings

Positive, leak-proof, long-lasting block
against
the
flow of electric current in piping systems.

PSI ElectroStop™ Isolating Fittings
are used worldwide for permanently controlling the flow of
electrical currents or electrically isolating pipe sections in pipes
and piping systems. Effective management of cathodic protection
programs results from the use of these highly reliable substitutes
for flanged insulating systems.
As
evidenced by the Alaska pipeline, ElectroStop isolating fittings are
capable of providing long term maintenance free service for pipes
subject to the most hostile environmental conditions on earth.
The ElectroStop™:
- Eliminates short circuits.
- Eliminates field assembly.
- Eliminates maintenance.
- Is less expensive.
- Is coated both internally and
externally.
- Is 100% electrically tested.
- Is completely weld inspected.
- Is manufactured in accordance
with ISO9002 specifications.

Benefits
ElectroStop™ monolithic
isolation fittings serve as a positive leak-proof, long-lasting
block against the flow of electric current in all piping
systems. When you bury the ElectroStop™ isolation fitting, you
bury maintenance costs forever - an especially important feature
for system operators and engineers.
- Eliminates Short Circuits.
Bolts, sleeves and washers - the major source of short circuits
in most isolation assemblies - are eliminated with the
ElectroStop™ isolation fitting.
- Eliminates Field Assembly.
The ElectroStop™ isolation fitting is completely
factory assembled and tested. There are no flanges, gaskets,
nuts, bolts, sleeves or washers to handle and consequently no
fluid leaks due to improper field assembly.
- Is Less Expensive.
Purchase the ElectroStop™ isolation fitting for less than the
cost of the component parts of insulated flange assemblies in
most pipe sizes. Install the ElectroStop™ isolation fitting for
less than the labor costs of installing an insulated flange
assembly.
- Is Coated Both Internally and
Externally.
A two-part epoxy is sprayed to a thickness of .010-.012" (.25 to
.30 mm) to within 2" (50.8 mm) of each weld end.
- Is 100% Hydrostatically
Tested.
All ElectroStop™ fittings undergo hydrostatic and cyclic
pressure tests at 1.5 times rated operating pressure in
accordance with the latest ANSI standards. Testing is conducted
between plates or end caps to ensure the most arduous
conditions.
- Is 100% Electrically Tested.
All ElectroStop™ fittings undergo a electrical resistance and
voltage test prior to shipping.
- Is Completely Weld Inspected.
All ElectroStop™ fittings undergo a weld inspection with
combinations of ultrasonic (UT), magnetic partical (MT) and dye
penetrant (LT) on all welds. In addition, X-ray tests can be
conducted upon request.
- Is Manufactured in Accordance
With ISO 9001:2000.
Quality Assurance Control over all stages of production is
ensured by close adherence to an in-place and on going ISO
9001:2000 quality assurance program which is constantly
monitored and subject to periodic audit.

Monolithic
Isolation Fitting Specification
Monolithic isolation fittings
shall be boltless and completely factory assembled in accordance
with the appropriate requirements of ASTM, API, DIN and BS
codes. All welds shall be butt-weld construction.
The dielectric isolation material
shall be a thermosetting fiberglass epoxy material. Sealing
shall be by two (2) static, self energized "O" ring seals housed
in accurately machined grooves, fully protected from cavitation
in full compliance with ASME design codes. Interior and exterior
coating shall be a two-part epoxy with a thickness of 12 to 15
mils to within 2" of each end. Testing shall be Electrical (@5
kV, 25 Mohm), Hydraulic (@ 1.5 x O.P.) and Weld
(Ultrasonic/Magnetic Particle/Dye Penetrant).
The Monolithic Isolation Fitting
shall be the ElectroStop™ Isolation Fitting as manufactured by
Pipeline Seal & Insulator, Inc., Houston, Texas.
Quality Assurance:
Each monolithic isolation fitting
shall be manufactured at a facility that has a Registered ISO
9001:2000 Quality Management System. Copy of current ISO
9001:2000 Registration shall be provided with material
submittal.
