POLYKEN 980 Anticorrosion Tapes(Inner Wrap)
|
POLYKEN 980&955 Cold Applied Tape Coating System |
System Description
The POLYKEN® 980,955 Pipe Inner Wrapping Tape is a multilayer system used for the protection of steel pipelines. POLYKEN® 1019,1027 Liquid Adhesives can be used as primers for this system. In addition to serving as primers, these liquid adhesives themselves represent an anticorrosion layer and provide a uniformly smooth contact surface to promote high adhesion of the coating system to the pipe. They are designed for machine or brush application and formulated with stress-corrosion cracking inhibitors. The Anti-Corrosion layer POLYKEN® 980 Inner Anti-corrosion Tape is engineered to assure a high bond to the primed surface with excellent conformability characteristics. The mechanical protection layer POLYKEN® 955 Gas Pipe Tape achieves a complete bond to the POLYKEN® 980 Anticorrosion Pipe Wrap Tape inner layer, providing maximum handling and in-service protection for the coating system. The adhesives in these and all POLYKEN® Anti-corrosion Pipe Repair Tape systems contain proven anti-microbial additives. The POLYKEN® 980/955 Pipe Anti Corrosion Materials can also be used for ductile iron pipes, in this case the use of POLYKEN® 1027 primer is recommended.

Material Calculation Formula :
(Width of Coating in inches) ×(Area of pipe in square feet)*
----------------------------------------------------------------------------=Squares **of Coating Required
(Width of coating in inches-Overlap in inches) ×100
*Area of pipe in square feet=(Diameter in inches)/12×3.1416×(Length in feet)
**One square=One hundred square feet=9.29 square meters
(Width of Coating in mm) ×(Area of pipe in square meter)*
-------------------------------------------------------------------------------=Square meter of Coating Required
(Width of coating in mm-Overlap in mm)
*Area of pipe in square meter=(Diameter in mm)/1000×3.1416×(Length in meter)
