DATASHEET4.2.3

APPLICATIONOnshore – Pipelines & Storage Tanks

CATHODIC ISOLATOR DATAElectrical Isolation for Effective Cathodic Protection

Cathodic protection, proven by decades of service in avariety of applications, prevents corrosion of buried orsubmerged metallic structures.

Cathodic protection is most efficiently and uniformly appliedwhen the primary structure is electrically isolated – i.e. allmetallic/electrical contacts with foreign structures areeliminated. Electrical isolation gives three main benefits:

• Restriction of the required protective current to thesurface of the primary structure to produce a uniformpolarised level of protection.

• Minimization of stray DC current interference.

• Prevention of galvanic current between metallic structures.

Safe Cathodic Isolation

The uniquely designed Cathodic Isolator™ developed byRustrol® Systems effectively confines the current needed forcathodic protection, while providing a safe grounding pathduring all types of electrical disturbances.

Cathodic isolation is a superior form of electrical isolation.Cathodic isolation maintains stringent electrical groundingrequirements and confines the protective current at thesurface of the primary structure. The result is highlyeffective, uniform protection against corrosion.

The Rustrol® Cathodic Isolator™ meets safety standards foreffective grounding and conforms to the need for safeoperating practices worldwide, ie; not to exceed 15Voltsrms (caution) potential most often stipulated by design.

The Cathodic Isolator™ provides all of the advantages ofelectrical isolation necessary for cathodic protection byblocking the protective current at the electrical isolatingdevice – such as across a pipeline isolating flange. As soonas the potential across the isolating flange exceeds thepre-set voltage threshold, the Rustrol® Cathodic Isolator™

responds instantly.

POLARISATION CELLS


REVISION 1


DATASHEET4.2.4

APPLICATIONOnshore – Pipelines & Storage Tanks

Rustrol® Systems are designed to protect personnel and equipment from electrical disturbances. Rustrol® Systemseffectively 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 DataThe Rustrol® Polarization Cell Systems are rated for up to 100 kA AC faultcurrent capacities, in 5 kA increments. Each Cell System is capable ofblocking 1.7 volts DC. A full product line is available to meet the challengeof all applications.

Rustrol® Polarization Cell Systems are typically specified for earthingapplications where major power disturbances are not the primaryexposure. Some examples include: decoupling a structure from groundrods, casings or other isolated earths. AC power pulses, lightning surges,stray DC interference and induced AC voltages are all standard applicationsfor 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 metallicstructures where electrical disturbances, caused by AC fault currents,present high-risk exposure. Typically, Rustrol® Polarization Cell Systems arespecified for direct connections across isolation flange assemblies; betweenpipe-type cable systems and station ground; or between cathodicallyprotected structures and the electrical grounding system neutral.

How Rustrol® Cells WorkRustrol® Polarization Cells contain pairs of pure nickel plates immersed inKOH electrolyte. The surfaces of these plates instantly polarize whenseparated metallic structures are connected to opposite terminals. Thepolarizing film blocks DC, to contain cathodic protection current, whilefreely passing AC. Personnel are safely protected from shock hazardsduring AC faults. Insulating fittings and equipment are protected duringelectrical disturbances.

Separated underground or submerged metallic structures are efficientlyprotected. Isolated structures, which must remain effectively grounded tothe AC utility network, are designed to meet this requirement in nationalelectrical safety codes. Installations specifying Rustrol® Polarization Cells forcathodic isolation, are regularly accepted by North American electricalinspectors.

Quality With A Proven Track Record• Rustrol® Polarization Cells and hardware are manufactured using only

pure metals as electrical conductors. Components machined andassembled match Rustrol's® high quality assurance standards.

• Researched and developed models are fully acceptance-tested to theapproval of independent high current test laboratories, prior tomarketing.

• Worldwide users of Rustrol® Polarization Cells report that maintenanceis minimal when operating at their operating temperature and ratedexposure conditions.

• Service life of more then 25 years with minimal variance in the level ofthe electrolyte is reported.

LINK SEALS


REVISION 1


DATASHEET4.4.2

APPLICATIONLink-Seal® mechanical seals are considered to be the premier method for permanently sealing pipes of any size passingthrough walls, floors and ceilings. In fact, any cylindrical object may be quickly, easily and permanently sealed, as theypass through barriers, by the patented Link-Seal design.

LINK SEAL DATA

Ductile iron, concrete, metal as well as plastic pipes may be hydrostatically sealed within walls to hold up to 20 psig(40 feet of head). Electrical or telecommunications cables may be sealed within conduit as they enter vaults ormanholes. The annular space between carrier pipes passing through casings may be sealed against the entry ofwater, soil or backfill material. With a wide variety of hardware/ elastomer combinations, Link-Seal mechanical sealsare easily configured to achieve the best possible match for service conditions encountered.

Saves time and money...Link-Seal mechanical seals install in up to 75% less time compared to lead-oakum joints, handfitted flashings, mastics or casing boots.

Positive hydrostatic seal...Link-Seal mechanical seals are rated at 20 psig (40 feet of head), which exceeds theperformance requirements of most applications.

Long seal life...Link-Seal mechanical seals are designed for use as a permanent seal. Seal elements are speciallycompounded to resist aging and attack from ozone, sunlight, water and a wide range of chemicals.

Maximum protection against corrosion...Standard fasteners with a two-part organic resin coating or corrosion resistant316 stainless steel.

Certification/Approvals...Factory Mutual Fire Approvals. Det Norske Veritas Marine Deck/Bulkhead PenetrationCertification. ANI (American Nuclear Insurers). Also a wide variety of approvals from various Federal agencies,associations, code groups, laboratories and organizations.

ISO Quality Assurance...Link-Seal mechanical seals are manufactured in an ISO 9002 certified facility.

Configure a Link-Seal to match your application...Colour coded EPDM, Nitrile, & Silicone elastomers may be used withvarious hardware options to match performance characteristics with service conditions
