PE Adhesive Tape ( Polyethylene Adhesive Tape )

Polyethylene Anticorrosive Tape Precautions In Use Are As Follows:
It Seems That The Use Of Polyethylene Anti-Corrosion Tape Is Very Simple, But In Actual Operation, There Are Many Precautions. If We Don't Pay Attention To These Subtle Places And Wind The Polyethylene Anti-Corrosion Tape On The Industrial Equipment At Will, It Is Likely To Lay a Serious Safety Hazard For The Subsequent Industrial Production. Therefore, It Is Very Important To Master Polyethylene Anti-Corrosion Tape For The Safety Of Industrial Production.
1. The Temperature Of Tape Unwinding Must Be Above 5 ℃, And The Anticorrosive Coating Construction Should Be Above - 5 ℃( Experience Has Proved That The Tape Winding Can Be Carried Out At a Lower Temperature Of - 30 ℃, But The Unwinding Temperature Should Be Ensured.) When The Ambient Temperature Is Lower Than 10 ℃, In Order To Ensure That The Adhesive Tape Has Good Bonding Strength Immediately, The Blowtorch Should Be Used To Heat The Steel Pipe And Bake The Adhesive Layer Of The Adhesive Tape.
2. If Necessary, The Weld Should Be Reinforced With 30-50 Mm Wide Narrow Tape, Which Should Be Covered On The Weld And Compacted By Hand Or Wooden Smooth Tools.
3. Use Appropriate Machinery Or Hand Tools To Spiral Wrap The Tape On The Primed Pipe According To The Lap Joint Requirements. The Tape Should Maintain a Certain Tension Force To Make The Tape Layer Closely Connected. When Winding The Tape, The Edge Seam Of The Tape Shall Be Parallel And Shall Not Be Twisted Or Wrinkled. There Should Be More Than 100 Mm Overlap At The Joint Of The Two Ends Of The Tape. If Necessary, Paint Primer On The Base Film At The End Of The Previous Section Of Tape Or Bake It Fully. After The Surface Is Dry, Lap The Starting End Of Another Section Of Tape. The Beginning And End Should Be Pressed Tightly With Smooth Wooden Tools To Prevent Them From Warping.
4. The Use Of Machinery Is a Powerful Measure To Ensure The Quality Of Tape Winding. It Is Difficult To Achieve Uniform Surface Quality And Consistent Tension Force By Hand Winding Tape. Only Under Special Circumstances, When Mechanical Construction Can Not Be Carried Out, Manual Winding Tape Can Be Used, But Narrow Tape Should Be Used.

5. Cold Or Hot Winding Construction Can Be Adopted For Factory Prefabricated Tape Winding, Which Can Be Tube Rotation (Manual Rotation Or Electric Rotation) Or Winding Equipment Rotation. 150-200 Mm Welding Reserved Section Shall Be Reserved At The End Of The Tube.
