Direct earth burial for cathodic protection of metallic structures. Cathodic Protection Cable is used in systems that protect metallic structures from electrolysis and corrosion. The product acts as a DC feeder cable to drain static electricity, providing cathodic protection for: Pipelines, well Casings, storage tanks, water towers, marine craft, bridges, pierspillings, railroad.

The Trenton Keyhole Patch Pad and Tools enable utilities to apply a coating to a pipe surface through a small-diameter hole or keyhole. The components include two tools (attached to extendable poles) and a patch pad with pre-applied coating.

TEMCOAT is a high temperature petrolatum wax coating compound that will not melt and can be applied at ambient temperatures up to 200 F. It does not require a primer or curing time and is easily hand applied.

Northtown zinc anode caps are engineered to fight corrosion. When the caps are threaded onto the bolts or studs, they become sacrificial anodes and protect the flanges, mechanical joints and other metal parts. Our zinc anode caps are precision made of the highest grade metal which meets or exceeds the requirements of ASTM B-418-80, 88 and MIL spec MIL-18001H, J, K. Corrosion of underground mechanical joint fittings may prove to be very costly, both in repair costs to pipelines and the untimely interruption to the vital flow of water, oil or gas. Most failures of pipelines can be directly related to the flange area where the two ends of the pipeline are attached by a studbolt nut joint. Northtown zinc anode caps are designed to sacrifice themselves rather than allowing the underground water, oil or gas pipeline flange area to succumb to the ravages of galvanic corrosion. The application of the threaded zinc cap to the bolt head forms a galvanic cell, thus causing the zinc anode cap to become a sacrificial anode, adding many years of life to the pipeline and in turn saving down time and high repair costs. Northtown zinc caps can provide many years of life to underground pipelines.

_____Compact, high strength, high copper alloy split-bolt has free-running threads and easy to grip wrench flats. Highly resistant to corrosion and season cracking, these split bolt connectors provide maximum pressure and assures a secure connection on all combinations of run and tap conductors. Type KS-3 accomodates 3 maximum size conductors.

Trenton Wax-Tape Primer is a blend of microcrystalline waxes, plasticizers, and corrosion inhibitors (no clay fillers). It has a paste-like consistency and is designed to displace moisture and wet the surface, ensuring adhesion of the tape. It is easily applied by hand.

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 shop applied coating. Innovative Tapecoat Gray adhesives incorporates an integrated primer 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.

A top plastic sheet formed with an igloo shaped dome and entry tunnel for the lead wire.A special elastomeric compound in the plastic dome, which is firm enough to resist flow at all normally encountered application and operation temperatures, but soft enough to mold itself around and completely cover the irregular welded profile.On either side of the dome is a double row of parallel, flexible serrations to assist with conforming abound small diameter pipe.A base of Royston Tac-Coat, a black unbacked elastomeric tape with exceptional adhesive properties, for bonding firmly to the metal surface, when used with Royston Roybond 747.

Poly-Ply plastic wrapper consists of three 50 gauge, clear, polyvinylidene chloride plastic, high cling membranes, wound together as a single sheet. It provides a mechanical and electrical barrier over graycoat while remaining flexible enough to conform to irregular shaped surfaces. It is inert and will not deteriorate, and is resistant to chemicals and bacteria commonly found in soil.

Insulation Couplings are an excellent and economical means of providing dielectric protection from electrolysis. Insulation Couplings stop electrolytic corrosion on all water piping where dissimilar metals are joined together.
