Calpico Wrapping Tape
|
Calpico
polyvinyl tape is formulated to produce the best anti-corrosion pipe
wrapping tape on the market today. It is a tough, all-weather tape and
retains its flexibility in all types of weather. Calpico is an ideal
joint tape as it conforms perfectly to irregular surfaces. It has
excellent corrosion resistance coupled with high adhesion properties and
flexibility which assures efficient application by machine or hand
wrapping.

CALPICO - Pipe Primer #22 - Calpico is a fast
drying primer especially developed to be used with Calpico PVC tapes.
Calpico pipe primer may be applied by brush or spray. Coverage is
300-400 square feet per gallon. |
Job Calculations
Primer
Coverage = 300-400 square feet/gallon
Example: You have 1,000 lineal feet of 6"
ID x 50 foot pipe and plan on half-lapping for the greatest protection.
How much primer and squares of tape is needed for the joints and the pipe for
each variation?
Solution:
PART 1: JOINTS - Calculate the tape needed for the joints using Table
A. 1000 ÷ 50 = 20 joints + 2 connection joints = 22 joints. On Table
A, locate 6" pipe in Column A. Read across to Column C. Divide the
number of joints by the value in Column C.
PART 2: PIPE - Using Table B Find 6" in column A
and move horizontally to column D. Multiply each value by 10 (1000
lineal feet ÷ 100 = 10) to find out how much is needed; Multiply the value in
Column E by 10 then divide by 300 to determine the number of gallons of
primer.
- 22 joints ÷ 7 Joints per 4" Roll = 3.14 = 4
rolls of 4" tape for joints
- 1.984 x 10 = 19.84 = 20 rolls using 2" tape at
minimum overlap of 1/2" + 2 contingency rolls = 22 Rolls
- 1.894 x 10 = 18.94 = 19 rolls using 4" tape at
minimum overlap of 1/2" + 2 contingency rolls = 21 Rolls
- 3.472 x 10 = 34.72 = 35 rolls using 2" or 4"
tape at half-lap (1" or 2") + 4 contingency rolls = 39 Rolls
- 173.600 x 10 = 1,736; 1736 ÷ 300 = 5.78 = 6 gallons
primer + 1 contingency gallon = 7 gallons
We recommend allowing 10-15% additional material for field
contingencies. Always better to have a little extra rather than come up
short on the job site.
