2020 11/30

System Description

POLYKEN® 934 Anticorrosion Polyethylene Tape is a cold applied tape coating system designed for the corrosion protection of field joints, fittings, and specialty piping. Anti Corrosion Self Adhesive Tape highly conformable backing and thick, aggressive adhesive also make it the ideal repair system for all types of main line coatings. The POLYKEN® 934 Anti Corrosion Adhesive Tape with very tacky adhesive has a release plastic liner to enable proper unwinding of the roll. Whether used as a double wrap system or as a single wrap with a mechanical layer, the Polyken 934 Anticorrosion Tape coating system is universally specified in the oil, gas ,water and chemical industries.

How to select coating materials

Eg :Total coating required thickness 3 mm with a minimum overlap of 50%.

You Can Choose followed two methods :

-1^st Singal Wrap with Overlap 50% :

PRIMER layer + 934-60(60mil=1.524mm) as single double wrap, total 3mm .

-2^nd Singal Wrap with an outer Wrap :

PRIMER layer + 934-40(inner tape-40mil=1.016mm)+955-20(outer wrap-20mil=0.508mm),total 3mm.

***Special Roll Size can be customized .

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)
