Polyethylene Anticorrosion Tape (
PE Anticorrosive Wrap Straps ) Is A Strip-Shaped Anti-Corrosion Material Composed Of Polyethylene Back Material And Pressure-Sensitive Adhesive Layer, Which Is Wrapped By Cold Wrapping To Form Pipeline Anti-Corrosion Layer. The Base Film Is Polyethylene Film And The Adhesive Layer Is Butyl Rubber, Which Has Good Mechanical Strength And Adhesive Sealing Performance.
According To The Percentage Of Adhesive Layer Thickness In The Total Thickness Of Adhesive Tape, Anti-Corrosion Tape Can Be Divided Into Thin Adhesive Tape With Adhesive Layer Thickness Accounting For 30-60% Of The Total Thickness Of Adhesive Tape And Thick Adhesive Tape With Adhesive Layer Thickness Not Less Than 70% Of The Total Thickness Of Adhesive Tape; According To Its Function, It Can Be Divided Into Anti-Corrosion Adhesive Tape (Inner Tape) And Protective Adhesive Tape (Outer Tape); Patching Tape Refers To Anti-Corrosion Adhesive Tape (Inner Tape).
Polyethylene Adhesive Tape Anticorrosive Coating Can Adopt Composite Anticorrosive Coating Structure Composed Of Primer, Inner Tape And Outer Tape, And Outer Tape Should Not Be Used Alone. The Anticorrosive Coating Structure Composed Of Primer And Thick Adhesive Tape Can Also Be Used.
Application Fields:
Polyethylene Anticorrosive Tapes Used For External Corrosion Protection Of Oil And Gas Transmission Metal Pipeline;
External Surface Anti-Corrosion Of Buried Steel Pipelines For Water Supply And Drainage And Gas Transmission In Chemical Industry And Urban Construction;
It Has The Characteristics Of Convenient Construction And No Pollution. Polyethylene Anti-Corrosion Tape Has Been Widely Used As External Anti-Corrosion Material For Oil And Gas Steel Pipelines Since 1960S. It Has A History Of More Than 50 Years Until 2019. Due To Its Excellent Anti-Corrosion Performance And Convenient Construction Performance, It Occupies A Certain Position In The Pipeline Anti-Corrosion Material System. And Because Of The Continuous Improvement Of Polyethylene Anti-Corrosion Tape Production Enterprises And Improve The Variety And Quality Of Polyethylene Tape, So That The Application Field Of Polyethylene Anti-Corrosion Tape Continues To Expand.
Type:
1. Composite Anti-Corrosion Tape (Butyl Rubber Type): The Earliest Common Inner Tape (Anti-Corrosion Adhesive Tape), Outer Tape (Protective Adhesive Tape), Patching Tape And Primer Constitute a Set Of Anti-Corrosion System; In The New Standard, Patching Tape Is Not Classified Separately, But Generally Refers To Anti-Corrosion Adhesive Tape (Inner Tape).
2. Polyethylene 600 Type Anticorrosive Tape: The Adhesive Layer Is Thick, And The General Thickness Can Be From 0.8 Mm To 4.0 Mm. It Is a New Kind Of Anticorrosive Tape. Traditionally, Modified Asphalt Is Used As Adhesive Layer; With The Adjustment Of The National Environmental Protection Policy, Some Manufacturers Use More Environmentally Friendly Butyl Adhesive Layer, Increasing The Sealing And Temperature Resistance Of The Tape.
3. Polyethylene Double-Sided Adhesive Type Anticorrosive Tape: This Kind Of Tape Has Compound Butyl Rubber On Both Sides, Which Is Generally Only Used As Anticorrosive Tape (Inner Tape). It Is Widely Used In South Asia Subcontinent, And Rarely Used In China, Mainly Because It Is Rarely Designed, And The Domestic Standard Is Not Perfect.
Polyethylene Anti-Corrosion Tape Specifications Generally Used For Reinforced And Extra Reinforced Anti-Corrosion Are As Follows:
Polyethylene Anticorrosive Tape (Anticorrosive Tape, Inner Tape) Series:
T140: thickness 0.40mm, width 50, 75, 100, 150, 230mm;
T150: thickness 0.50mm, width 50, 75, 100, 150, 230mm;
T180: thickness 0.80mm, width 50, 75, 100, 150, 230mm;
Polyethylene protective tape (protective tape, outer tape) series:
T240: thickness 0.40mm, width 50, 75, 100, 150, 230mm;
T255: thickness 0.55mm, width 50, 75, 100, 150, 230mm;
T280: thickness 0.80mm, width 50, 75, 100, 150, 230mm
There Are Two Methods For Construction: Using Inner Tape (Anti-Corrosion Tape) And Outer Tape (Protective Tape) At The Same Time, Or Directly Winding With Anti-Corrosion Tape, As Long As The Total Thickness Of The Anti-Corrosion Layer Of The Tape After Winding Meets The Requirements Of The Standard.
