Petrolatum Tape Below Ground 100mm x 10m
Below ground petrolatum tape, 50mm x 10m. Petrolatum tape is the 3rd step in the petrolatum process. Petrolatum tape is a synthetic fabric-based tape that is non-stitched and Impregnated and coated with a petrolatum-based compound. Recommended for protecting underground pipelines, joints, fittings and more. Petrolatum tape is used to waterproof seal surfaces above and below the ground (2 types, above ground and below ground), preventing corrosion, even when the seal is underwater.
Product Description
INSTALLATION OF PETROLATUM TAPE
RAM PETROLATUM TAPES are extremely surface tolerant and unyielding to moisture, acids, alkalis and salt solutions. RAM PETROLATUM TAPE systems utilize microcrystalline waxes which achieves excellent characteristics including high conformability, superior adhesion / amalgamation to itself and substrates whilst being user friendly to semi skilled applicators.
Surface Preparation
Wire brush dirt, loose rust and foreign matter from surface to be protected.Surfaces should be reasonably dry. On wet surfaces use RAM Marine Primer.
Priming
Apply a thin even film of RAM Primer over the metal surface by gloved hand.
Filling
RAM Moulding Mastic should be used where necessary to improve contours at fittings to achieve a streamline contour. The wrapped fitting with the specified overlap must have no voids, air bubbles and wrinkles.
Taping
Start applying the RAM Petrolatum Tape with a full circumferential turn around the fitting and utilize a nominal 50% overlap to achieve a double thickness of tape. Apply tape ensuring firm tension and then smooth down by hand to exclude any moisture and/or water.
On each new roll of tape, underlap the new roll on previous by a minimum 100 mm.
Overwrapping
RAM High Temperature Outer Wrap should be spirally wrapped (similar to previous procedure) under tension to guarantee contact to achieve a nominal 50% overlap.
