Tapes

Scotchrap 50 and 51 Tapes are tough, polyvinyl chloride

based tapes with special high tack adhesives formulated to

resist corrosion of metal piping systems above and below

ground, ﬁttings and joints on all mill-coated pipe and

electrical conduit systems. Scotchrap 50 and 51 tapes are:

• Resistant to corrosive salt water, soil acids, alkalies and

salts, common chemicals, chemical vapors, and exposure

to outdoor weathering and sunlight.

• Resistant to impact, abrasions, punctures, and tears.

Scotchrap 50 is a highly conformable, all-weather 10 mil

(0,254 mm) thick tape designed for application over a wide

temperature range. Scotchrap 51 provides similar qualities

in a thicker, 20 mil (0,508 mm) tape. Both tapes have high

electric strength, excellent insulating properties.

While the chart gives coverage data for most common sizes, the following formula may be helpful for non-standard items: Squares of Tape = π (LP) (DP) TW 1200 (TW-OV) Where π = 3.14 LP = length of pipe (ft.) DP = outside diameter of pipe (in.) TW = tape width (in.) OV = overlap of tape (in.) When using metrics, squares of tape = π (LP) (DP) TW 9290 (TW-OV) Metric Conversions 1 inch = 25,4 millimeters 1 foot = 0,3048 meter 1 sq. ft. = 0,092 sq.
