Royston Royfill 406 hot applied Casing Filler for large or multiple casing projects. This casing ﬁller is a specially formulated, blend of corrosion inhibitors, petrolatum wax and inert solids, installed by a custom heated pumping tanker. ROYFILL 406 provides an effective protective environment for preventing and eliminating active corrosion and electrolysis from the annular space between the carrier pipe and casing
For the prevention of galvanic and atmospheric corrosion in casings with new or existing pipe. This ONE STEP, hot injected, wax blend ﬁlls and coats the pipe and casing, re-coating areas of damaged coating and eliminating electrolytic shorts by totally encompassing these areas with a high dielectric, nonconductive, protective barrier of wax and corrosion inhibitors. As the casing is injected with ROYFILL 406 time proven formula, oxygen and moisture are eliminated from the casing and are prevented from being re-introduced into the protected space.
Casing End Seals
EnviroSeal End Seals are the preferred product to use in conjunction with Royﬁll 406. They are designed to take the heat and pressure associated with hot ﬁlls. In the absence of EnviroSeal End Seals, good quality casing end seals should be installed and tested. End seals should have the ability to handle the pressure and high temperature of the application.
One Step Application
No need for pre-treating casings prior to application. The corrosion inhibitor is already in the casing ﬁller blend.
Tanker Truck Installation
ROYFILL 406 hot injected casing ﬁller is pumped into the low end, bottom casing vent with the use of an insulated, heated tanker truck and factory trained installers.
