Pipe Marking Tape | Polyethylene ( PE ) Marker Tape
Pipe Marking Tape | Polyethylene ( PE ) Marker Tape Has The Advantages Of Cold Winding Tape, Convenient Construction, No Environmental Pollution, Excellent Marker Performance, Long Service Life And Low Comprehensive Cost. Widely Used In Oil And Gas, Petrochemical, City Gas, Power Supply And Metallurgical Shipbuilding Pipeline Engineering Of Steel Pipeline Marker.
Polyethylene Marker 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 Marker Belt (Inner Belt), Protective Belt (Outer Belt) And Patching Belt. According To The Requirements Of Marker Coating Grade, It Can Be Divided Into Ordinary Grade, Reinforced Grade And Extra Reinforced Grade.
Ordinary Grade ≥ 0.70, One Layer Of Primer, One Inner Layer And One Outer Layer
Reinforcing Grade ≥ 1.40, One Layer Of Primer And One Layer Of Inner Tape (Overlapping Is 50 ~ 55% Of The Tape Width)
One Layer Of Outer Tape (Lap 50 ~ 55% Of The Tape Width)
Since 1960s, Marker Adhesive Tape Has Been Widely Used As External Marker Material For Oil And Gas Steel Pipelines For More Than 40 Years. Because Of Its Excellent Marker Performance And Convenient Construction Performance, It Occupies a Certain Position In The Pipeline Marker Material System. And Because Of The Continuous Improvement And Improvement Of Domestic Polyethylene Marker Adhesive Tape Production Enterprises, The Variety And Quality Of Polyethylene Adhesive Tape Can Meet The Technical Requirements Of Various Kinds Of External Marker Of Buried Pipelines, So As To Expand The Application Field Of Polyethylene Marker Adhesive Tape.
Polyethylene Marker Adhesive Tape Can Be Divided Into Inner Tape And Outer Tape. The Product Has a Variety Of Specifications And Is Widely Used In Pipeline Marker. The Product Has a Variety Of Advantages.
The Marker System Of Polyethylene Marker Tape Is Generally Composed Of Primer, Marker 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.
Polyethylene Marker Tape Has The Following Performance Advantages:
1. There Is Enough Adhesive Force Between Polyethylene Marker Tape And 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. Polyethylene Marker 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. Polyethylene Marker 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 Marker Coating Will Not Occur When The Pipe And Soil Are Displaced After Buried.
4. The Marker Coating Of Polyethylene Marker Tape Has Good Anti Cathodic Stripping Performance. The Adhesive Tape Anticorrosion Pipeline Has Reliable Protection Potential And Stable Protection Current.
5. Polyethylene Marker Tape Has High Electrical Insulation, 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.
At Present, The Domestic Butyl Rubber Polyethylene Composite Marker Adhesive Tape Is Made By Co Extrusion With The Same Technology As Abroad. The Performance Of The Product Reaches The International Level Of Similar Products, And The Quality Index Meets The Requirements Of American Awwa c214 And National Sy / t0414 Standards. The Performance Of The Product Is The Same As That Of Foreign Brands.
