The ElectroStop monolithic isolation joints are a leak-proof, maintenance-free and long-lasting block against the flow of electric current in all piping systems
The ElectroStop eliminates short circuits and field assembly. The ElectroStop is coated internally and externally to prevent corrosion and is 100 per cent hydrostatically, electrically and weld tested. All ElectroStop monolithic isolation joints are manufactured under an ISO Quality Management System.
Industry Challenges
Monolithic Isolation Joints eliminate a number of the variables which commonly cause issues with isolation joints (ie. nuts, bolts, sleeves, and washers), and greatly simplify the installation process. In opposition, many end users have concerns regarding the raw materials, manufacturing process, and testing which detracts from industry confidence in MIJs. A MIJ delivered to a job site is a completed fitting, with no access or method to evaluate the internal components or assembly process. This leaves the end-user having to rely on the manufacturer’s processes to ensure traceability and the delivery of a quality product.
Eliminates Short Circuits
Bolts, sleeves and washers, the major source of short circuits in most isolation assemblies, are eliminated with the ElectroStop monolithic isolation joint. Each joint is electrically tested during production to assure integrity, performance and isolating properties.
Eliminates Field Assembly
The ElectroStop isolation joint 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.
Coated Both Internally and Externally
A two-part bonded epoxy is sprayed to within 2” (50.8mm) of each weld end. Each joint is tested for coating thickness uniformity and for coating holidays.
100 per cent Hydrostatically Tested
All ElectroStop joints undergo hydrostatic pressure tests at 1.5 times their rated operating pressure in accordance with ASME B31.3 standards. Testing is normally conducted for 30 minutes on joints up to 6” and for 60 minutes on 8” to 24” joints, but can be longer upon customer request. A pneumatic test is held at 87 psi for 10 minutes.
Completely Weld Inspected
All ElectroStop joints undergo a weld inspection with a combination of phased array ultrasonic testing (PAUT), visual testing (VT), and magnetic particle testing (MT) on all welds. In addition, radiography testing (RT) can be conducted upon request. All ElectroStop joints are manufactured under an ISO 9001; 2015 Quality Management System.
