Polypropylene ( PP ) Reinforced Fiber Anticorrosive Tape Is Used For Water Supply And Drainage In Chemical Industry And Urban Construction. The Main Models Are 760, 780, Bl-10, Rd-6 And Ht-1100. This Type Of Pipeline Anti-Corrosion Tape Is Widely Used In Oil, Natural Gas, Chemical Industry, Urban Construction Of Water Supply And Drainage Pipeline, Oil And Gas, Gas Transmission Steel Pipeline And Steel Buried Storage Tank Of External Anti-Corrosion And Repair Engineering.
The Base Material Of The Anti-Corrosion Belt Is a Unique Modified Polypropylene Woven Fiber Cloth, And Butyl Rubber Modified Asphalt Is Used As The Anti-Corrosion Adhesive Layer. Its Base Material Is Fiber Structure, Which Can Effectively Resist The Creep Damage Caused By Soil Stress. The Aging Test Shows That Its Corrosion Resistance Life Is More Than 50 Years, And The Test Indexes Are Much Higher Than Those Of Sy / t0414-2007, Which Fully Meet The American Ansi / Awwac209-00 And Nacemr0274-95 Indexes. It Is The Best Choice In The Pipeline Cold Anti-Corrosion Construction Belt, And Also The Most Economical Choice For Anti-Corrosion.
