Casing Filling
Water or water vapor is present in most pipeline casings making possible galvanic corrosion of the carrier pipe. Also, a “water short” can occur through the water in the casing, allowing cathodic current to flow through the water and on to the pipe in the 
casing. Under these circumstances, cathodic current is increased and the casing is sacrificed as well. Casing filler prevents this from occurring.
Further, in some instances, the pipe may be shorted to the casing through a direct metal-to-metal contact and filling the casing might correct this condition on some occasions. In any case, it is difficult, if not impossible to cathodically protect pipe in casing, so that filling of the casing will protect the pipe from corrosion regardless of the circumstances.
Fill-Coat #2
| Advantages |
|
Fill-Coat #2 Casing Filler is a petrolatum wax-based corrosion preventative compound, used to fill the pipeline casing annulus, specifically designed for cold installation for small quantity requirements. It prevents corrosion by displacing water that is present and preventing water from re-entering the casing.
Specifications:
| Color | Dark Brown |
| Specific gravity @60°F | 0.80~0.90 |
| Pour point | 80~100°F (27~38°C) |
| Flash point | 300°F (149°C) |
Packaging:
55 gallon drums
Fill-Coat #6
| Advantages |
|
Fill-Coat #6 is a cold-installed/high temperature petroleum-based casing filler compound that can be installed at ambient temperatures as low as 50°F (10°C) with portable pumps. The product is used in bridge abutment casings, and it can be used in casings with elevated temperatures.
Specifications:

| Flash point | 350°F minimum |
| Temperature range | 30~225°F (-1~107°C) |
| Consistency | grease-like |
| Dielectric strength | > 100 volts/mil |
| Density | 7.898 lb/gal |
Packaging:
50 gallon drums
Pre-Con
Pre-Con is a liquid casing water conditioner for pipeline casings. It consists of "wetting" and filming agents, vapor phase inhibitors, alkaline media additives and antibacterial conditioners.
Pre-Con is poured into the casing prior to the installation of Trenton Fill-Coat Casing Filler. The method of using these two materials together is a Trenton Corporation patented process. Pre-Con conditions the water accumulated in the casing so that any small amounts of water that may be entrapped after installation of Fill-Coat Casing Filler are inhibited and no corrosion should occur.
Specifications:
| Color | Amber |
| Specific gravity @60°F | 1.13 |
| Flash point | none |
| Solubility in water | 100% |
Packaging:
Pre-Con is packaged in one-gallon pails.
Short-Stop End Insulator
Short-Stop casing end electrical insulator is made of compression-resistant neoprene rubber and installed in casing ends. In addition to dielectric properties, Short-Stop is resistant to oil, water, ozone and chemicals. The Short-Stop insulator will also withstand a wide range of temperature variations.
The Short-Stop end insulator is installed in casing ends between carrier pipe and casing to prevent metal-to-metal shorts. Because of its unique slab form, it has no metal components that might cause future shorting-out.
Specifications:
| Color | Black |
| Composition | Neoprene |
| Specific gravity | 1.23 |
| Hardness durometer | 60 |
Compression: 1/2 inch thick x 1 inch sqr 1 inch thick x 1 inch sqr |

Packaging:
Standard width is 6 inches.
Seal-Wrap End Seal
Seal-Wrap is a casing end-seal wrapper consisting of a heavy woven glass coated with a butyl mastic of high dielectric quality wrapped around the end of the casing and on the carrier pipe. It is then strapped in place with stainless steel banding.
