Fill-Coat® #1

Fill-Coat #1® is a low melt point, hot-installed petrolatum compound that sets up relatively firm at ground temperatures commonly found in normal pipeline operations. It has good “wetting” and adhesion characteristics and prevents possible corrosion of pipe in casings.

Fill-Coat #1 meets the Department of Transportation requirements for shorted casings, and is expertly installed from readily available inventories by Trenton personnel.

End Use

Fill-coat #1 is used to displace water that may otherwise be present in the annular space between a casing and internal carrier pipe.

Application Procedures

Fill-Coat #1 is delivered to the casing site in Trenton insulated tank trucks and pumped through an opening at the top of the casing vent until the annulus between the casing and the carrier pipe is filled.


Material is pumped directly into the casing from Trenton’s heated tankers.
