Polyethylene anticorrosion tape is cold applied tape coating system for corrosion protection of oil, gas, petrochemical, and waste water underground or overhead pipelines. The outer-layer tape backing shall be compounded so that it will be resistance to outdoor weathering. The outer-layer tape shall be applied after the inner-layer tape by hand or with a wrapping machine. Ii structure The specification of the tape consists of two layers, adhesive layer and film backing Adhesive: butyl rubber Outer layer: special blend of stabilized polyethylene Iii features: Excellent adhesion to inner-layer tape and self Resistant to UV Can be applied over a wide temperature range Good conformability and consistent uniform thickness Easily applied with no special equipment Compatible with common pipe coatings Excellent resistance to cathodic disbonding Meets astm d 1000 standard Cold applied technical datas: Outer wrap tape: xunda-t200 series TypeT 250T 265T 280 Total thickness0.51 mm0.65 mm0.80 mm Film0.38 mm0.51 mm0.63 mm Adhesive0.13 mm0.14 mm0.17 mm Elongation at break„d 400% Tensile strength45.3 n/cm50.8 n/cm60.1 n/cm Yield strength35.9 n/cm43.4 n/cm45.8 n/cm Dielectric breakdown32.9 kv/mm43.5 kv/mm45.2 kv/mm Cathodic disbandment0.24 in radius 6.4 mm Volume resistivity2.5 x 1012 ohm.M Water vapor transmission rate „t 0.08 gm/m2/24h Water absorption rate < 0.07% Recommended application temperature -50 to +600 c ColorWhite Available roll size (width x length)2" to 9" x 50 to 800 feet.
