Product Description
3M Scotchrap 51 Printed Vinyl Corrosion Protection Tape is a premium, 20 mil black PVC tape with a high-tack, pressure-sensitive rubber adhesive that protects metal pipe, conduit and fittings from corrosion above and below ground. It is twice the thickness of 3M Scotchrap 50, with double the breaking strength and a higher dielectric breakdown, for heavier-duty wrapping of straight pipe, conduit and field joints on mill-coated pipe. This is the printed version of the backing. It is also available unprinted.
Scotchrap 51 resists corrosive salt water, soil acids, alkalis, salts, common chemicals and chemical vapors, as well as UV and outdoor weathering. It stands up to impact, abrasion, punctures and tears, conforms well to fittings and welds, and applies in all weather from 10 to 150°F with a service range of -55 to 175°F. The flexible PVC backing adds mechanical strength and electrical insulation, with a 20,000 volt dielectric breakdown.
3M requires all metal surfaces to be coated with 3M Scotchrap Pipe Primer before wrapping for the tape to perform properly. Irregular shapes such as fittings and valves can be filled with Scotchfil putty first. For severe construction or soil conditions, 3M suggests extra thickness or a protective overwrap.

Instructions
- Make sure surfaces are clean, dry and free of oil, grease and other contaminants. Blast removal of rust and scale is preferred.
- Chip, grind or file off welding slag, spatter, sharp edges and burrs.
- Apply a uniform, continuous coat of 3M Scotchrap Pipe Primer to all metal surfaces and let it dry.
- Fill irregular surfaces such as fittings and valves with Scotchfil putty.
- Cover the weld bead with one wrap of tape, then wrap the entire surface.
- Spirally wrap straight pipe and conduit. Field joints on mill-coated pipe can be spirally wrapped, cigarette wrapped or wrapped with wide tape.
- For severe construction or soil conditions, add extra thickness or a protective overwrap.
- For buried pipe, protect the wrap during handling, lowering and backfilling. Keep the ditch and backfill free of rocks and sharp objects, and cover the pipe with a layer of clean soil before general backfill.
