INSULATING FLANGE KITS REVISION 1 APPLICATION Flange insulation kits for metallic pipelines are available for all flange sizes, types, pressure ratings and materials. Flange insulation kits are commonly installed at each end of a pipeline to electrically isolate the pipe for other buried foreign metallic structures and plant grounding systems therefore limiting the amount of cathodic protection current required to protect the pipeline.
FLANGE INSULATION KIT DATA
TYPE "E" GASKETS Have the same outside diameter as the flanges, and are made with precision-located bolt holes. They are easy to centre and will prevent foreign material from becoming lodged between the flange faces and "shorting out" the flange insulation. Type "E" gaskets are available in a wide variety of materials.
TYPE "F" GASKETS Are made to fit within the bolt hole circle of the flange faces. The outside diameter of the gasket is slightly larger than the inside diameter of the bolt hole circle. They are available in a wide variety of materials.

CATHODIC ISOLATOR DATA Electrical Isolation for Effective Cathodic Protection
The uniquely designed Cathodic Isolator ™ developed by Rustrol® Systems effectively confines the current needed for cathodic protection, while providing a safe grounding path during all types of electrical disturbances.
Cathodic protection, proven by decades of service in a variety of applications, prevents corrosion of buried or submerged metallic structures. Cathodic protection is most efficiently and uniformly applied when the primary structure is electrically isolated isolated – i.e. all metallic/electrical contacts with foreign structures are eliminated. Electrical isolation gives three main benefits: • Restriction of the required protective current to the surface of the primary structure to produce a uniform polarised level of protection. • Minimi Minimizatio zation n of stray DC current current interference interference.. • Prevention of galvanic current between metallic metallic structures. structures.
Safe Cathodic Isolation Cathodic isolation is a superior form of electrical isolation. Cathodic isolation maintains stringent electrical grounding requirements and confines the protective current at the surface of the primary structure. The result is highly effective, uniform protection against corrosion. The Rustrol® Cathodic Isolator™ meets safety standards for effective grounding and conforms to the need for safe operating practices worldwide, ie; not to exceed 15Volts rms (caution) potential most often stipulated by design. The Cathodic Isolator ™ provides all of the advantages of electrical isolation necessary for cathodic protection by blocking the protective current at the electrical isolating device – such as across a pipeline isolating flange. As soon as the potential across the isolating flange exceeds the pre-set voltage threshold, the Rustrol ® Cathodic Isolator™ responds instantly.

POLARISATION CELLS REVISION 1 APPLICATION Onshore – Pipelines & Storage Tanks Rustrol® Systems are designed to protect personnel and equipment from electrical disturbances. Rustrol ® Systems effectively block cathodic protection DC voltages; all other electrical disturbances are freely conducted to ground, such as: • AC Fault Currents • Mitigation of induced AC Voltages • Lightning
Rustrol® Polarization Cell Systems Data The Rustrol® Polarization Cell Systems are rated for up to 100 kA AC fault current capacities, in 5 kA increments. Each Cell System is capable of blocking 1.7 volts DC. A full product line is available to meet the challenge of all applications. Rustrol® Polarization Cell Systems are typically specified for earthing applications where major power disturbances are not the primary exposure. Some examples include: decoupling a structure from ground rods, casings or other isolated earths. AC power pulses, lightning surges, stray DC interference and induced AC voltages are all standard applications for the Rustrol ® Polarization Cell. All Cells are rated to safely pass _ second (30 cycle) AC fault current, with a terminal potential rise across the Cell, not exceeding 15 volts rms at 20°C. Rustrol® Polarization Cells optimize the safety of personnel and equipment. Rustrol® Polarization Cell Systems are utilized to decouple massive metallic structures where electrical disturbances, caused by AC fault currents, present high-risk exposure. Typically, Typically, Rustrol ® Polarization Cell Systems are specified for direct connections across isolation flange assemblies; between pipe-type cable systems and station ground; or between cathodically protected structures and the electrical grounding system neutral.
How Rustrol® Cells Work Rustrol® Polarization Cells contain pairs of pure nickel plates immersed in KOH electrolyte. The surfaces of these plates instantly polarize when separated metallic structures are connected to opposite terminals. The polarizing film blocks DC, to contain cathodic protection current, while freely passing AC. Personnel are safely protected from shock hazards during AC faults. Insulating fittings and equipment are protected during electrical disturbances. Separated underground or submerged metallic structures are efficiently protected. Isolated structures, which must remain effectively grounded to the AC utility network, are designed to meet this requirement in national electrical safety codes. Installations specifying Rustrol ® Polarization Cells for cathodic isolation, are regularly accepted by North American electrical inspectors.
Quality With A Proven Track Record • Rust Rustro roll® Polarization Cells and hardware are manufactured using only pure metals as electrical conductors. Components machined and assembled match Rustrol's ® high quality assurance standards. • Researched and developed developed models are fully acceptance-tested to the approval of independent high current test laboratories, prior to marketing. • Worldwi Worldwide de users users of Rustrol Rustrol ® Polarization Cells report that maintenance is minimal when operating at their operating temperature and rated exposure conditions. • Service life of more then then 25 years with minimal variance in the level of the electrolyte is reported.

THERMITE WELD EQUIPMENT REVISION 1 APPLICATION Onshore, Marine and Concrete Structures
THERMITE WELD DATA Thermite welding is a simple, inexpensive and efficient method of attaching a copper conductor cable to steel or cast iron. It is particularly useful for connecting cathodic protection cables to pipelines including test leads, negative and bonding cables. The welding process uses a high temperature reaction charge of powdered copper oxide and aluminium which when ignited produces aluminium oxide and super heated copper.

HANDY CAPS REVISION 1 APPLICATION Coating repair for Pin Brazed or Themit Weld cable connections on pipelines
Exothermic Weld Grounding Connection • No Liquid Primer Needed • Easy Field-Applied Corrosion Protection • Ideal for Keyhole Applications • Dome and Tunnel Provide Easy Access • Tapecoat Gray Adhesive Eliminates Liquid Primer • Elastomeric Compound Encases Weld Profile • Serrations Conform to Small Diameters Handy Cap IP is a prefabricated assembly designed to provide quick, field-applied corrosion protection to anode and test lead wire welds on metal pipe and tanks. This economical product is ideal for use in limited access applications. New Handy Cap IP now adds the innovative technology of Tapecoat Gray Adhesive to its unique design. The integration of a primer in Tapecoat Gray makes field application of Handy Cap IP easier and more economical. Tapecoat Gray Adhesive bonds the tough outer shell of the Handy Cap IP to the bare metal weld area and surrounding plant applied coating. Innovative Tapecoat Gray incorporates an integrated primer in its adhesive and provides exceptional bonding without the costly application of liquid primer. A protective compound within the dome molds itself over the irregular welded profile and encases the exothermic connection.
TECHNICAL SPECIFICATIONS Application Information: 1. Clean all mud, dirt, grease, oil and other contaminants from the metal surface and mill coating which is to be covered. The Handy Cap IP incorporates an integrated primer in its Tapecoat Gray Adhesive and does not require the use of a liquid primer prior to application. 2. Remove the release paper from the bottom of the Handy Cap IP. IP. Bend the plastic sheet inward at the serrations when applying to small diameter pipe. Position and place the Handy Cap IP on the welded area with the tunnel over the lead wire. 3. Push the dome of the cap firmly into the weld area. Lift the lead wire away from the pipe and squeeze the adhesive compound completely around and underneath the wire. Push the lead wire back down on the pipe and press the elastomeric compound into firm contact with the pipe over the entire area. No further protection is required when the Handy Cap IP covers the entire exposed metal area. Uncovered areas should be protected with primerless Tapecoat or Royston tapes. Remove the narrow plastic release film to accommodate tool use for keyhole applications
