Polyethylene Repair Tape ( PE Tubing Repair Tape )

Polyethylene Repair Tape ( PE Tubing Repair Tape ) Price Is Different According To Different Material Types, Such As 510mm * 20m Specification, Polyethylene Material, Which Is Suitable For External Anti-Corrosion Of Steel Pipeline In Oil And Gas, Petrochemical, City Gas, Electric Power, Water Supply, Metallurgy, Shipbuilding And Other Pipeline Projects.
Repair Tape Is Composed Of Base Film And Adhesive Layer. The Base Film Is Polyethylene Film And The Adhesive Layer Is Butyl Rubber. It Has Good Mechanical Strength And Adhesive Sealing Performance. According To Its Function, It Can Be Divided Into Anti-Corrosion Belt (Inner Belt), Protective Belt (Outer Belt) And Patching Belt. According To The Requirements Of Anti-Corrosion Coating Grade, It Can Be Divided Into Ordinary Grade, Reinforced Grade And Extra Reinforced Grade.
Tape Is Usually Divided Into Inner Tape And Outer Tape. The Product Has a Variety Of Specifications And Is Widely Used In Pipeline Anti-Corrosion. The Product Has a Variety Of Advantages.
Polyethylene Repair Tape Anti-Corrosion System Is Generally Composed Of Primer, Anti-Corrosion Tape (Inner Tape) And Protective Tape (Outer Tape). The Primer Is Made Of Butyl Rubber And Tackifying Resin By Organic Solvent, Which Ensures Good Adhesion With Steel Pipe. The Inner And Outer Tapes Are Composed Of Polyethylene Base Film And Butyl Rubber Adhesive, Which Has Good Mechanical Strength And Sealing Performance, And Butyl Rubber Also Has Self Repairing Function Of Self Melting Bonding.

1.There Is Enough Adhesive Force Between The Tape And The Steel Pipe, And The Peel Strength Is 18-30n / Cm. It Can Effectively Prevent The Liquid Medium From Penetrating Into The Surface Of The Steel Pipe, And It Can Still Maintain High Bonding Strength After Many Years Of Buried.
2.The Tape Has Good Elongation At Break And Ductility. It Can Maintain Its Flexibility In a Wide Temperature Range, And The Elongation At Break Of Conventional Products Is 150-500%. Polyethylene Adhesive Tape Can Be Wound At - 34 ℃ And Used For a Long Time At - 40 ℃. Its Brittleness Temperature Is - 70 ℃  。
3.The Adhesive Tape Has High Strength, And Its Tensile Strength Is More Than 20Mpa. It Can Resist The General Mechanical Force Of Pipeline Loading And Unloading And The Stress Of Soil After Buried. Because Of Its Smooth Surface, The Displacement And Delamination Of Anti-Corrosion Coating Will Not Occur When The Pipe And Soil Are Displaced After Buried.
4.The Anticorrosive Coating Of Adhesive Tape Has Good Cathodic Stripping Resistance. The Adhesive Tape Anticorrosion Pipeline Has Reliable Protection Potential And Stable Protection Current.

5. Tape Has High Electrical Insulation And Low Water Absorption And Water Vapor Permeability. Its Water Absorption Is Less Than 0.02%, And Its Electric Breakdown Strength Is More Than 40 Kv / Mm.
