ElectroStop Monolithic Isolation Joints

The ElectroStop monolithic isolation fittings will 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 Electro Stop isolation fitting for less than the labour costs of installing an insulated flange assembly.

Is Coated Both Internally and Externally
A two part epoxy is sprayed to a thickness of .010-.012in (.25 to .30mm) to within 2in (50.8mm) of each weld end

Is 100 percent 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 percent Electrically Tested
All ElectroStop fittings undergo an 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 particle (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 ongoing 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 fibreglass epoxy material. Sealing shall be by two static, self energized O ring seals housed in accurately machined grooves, fully protected from cavitations 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 2in of each end. Testing shall be Electrical (5kv, 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.
