Crowned with the title championship in anticorrosion, it represents the highest level of cold-applied anticorrosion tapes at home and abroad. It can be used for the purpose of steel pipe and underground steel tank surface corrosion resistance and rehabilitation for various pipelines in facility projects of petroleum, petrochemical industry, city gas, oil and gas storage and transportation, power, water supply etc. Therefore, it has been recommended by National Construction Department, Environmental Protection Bureau to take place of pitch glass fabric and epoxy coal pitch. Easy and convenient in application it performs well in shock resistance, aging resistance, stretching resistance, UV resistance, and adhesive strength. The backing material of the product is modified PP woven fabric cloth, and the anticorrosion layer of it is butyl rubber modified asphalt. Since its backing material is of fabric structure it can resist effectively the creep caused by soil stress. In addition, the ageing test proves that its service life is beyond 50 years and all the indexes of the items surpass the standard prescribed in SY/T0414-98 and reach that of ANSI/AWWAC209-00 and NACEMR0274-95. It is the best choice for cold anticorrosion project and also the most economical one.II Performance IndexIII Methods of Application1) Surface treatment: Remove rust, welding spatter, burr, oil or filth and keep it clean and dry. If the rust is removed manually, the effect should reach St3; if mechanically, the effect should reach Sa2 and comply with SYJ4007 86.2) Primer coating: Specialized matching primer is supposed to be used. During the process keeping it away from the fire, mix it evenly and use clean brush, roller or other mechanical method to coat it. The appropriate primer quantity applied is 12L by manual coating, and 20L by mechanical coating.3) 5 to 10 minutes after the prime coating surface dried, the wrapping can be started. 4) Back to the duct: After passing all the inspection, it can be put back to the duct.IV Transportation and Storage1) Keep it away from insolation, rain, or pressing.2) If it has been stored or transported in the temperature below 5, it has to be put in the place at about 20 for 48hours before it is installed.3) The storage time is 12 months. It should be kept in a cool place at530,75, away from heat or open fire.使用方法：(2)、涂底漆：应采用专用配套底漆，使用时远离火源，搅拌均匀并用干净毛刷、滚子或其它机械方法均匀涂敷。底漆用量：手工涂敷 12/L 机械涂敷 20 /L (3) 、待底漆表干( 一般 5 一 10 分钟后)即可缠带。 (4) 、下沟回填：经质量检查验收合格即可下沟。 四、运输贮存: (1) 、。 (2) 、在运输或贮存中受到 5以下暴冻时，需在 20左右存放 48 小时，方可施工。 (3) 、应在阴 ，温度 530，温度75库房中存放，储存期 12 个月，并远离热源与明火。2)Primer coating:Specialized Methods of Application matching primer is supposed to be used.During the process keeping it away from the fire,mix it evenly and use clean brush,roller or other mechanical method to coat it.The appropriate primer quantity applied is 12m/Lby manual coating,and 20m/Lby mechanical coating. 3)5 to 10 minutes after the prime coating surface dried,the wrapping can be started, 4)Back to the duct:After passing all the inspection,it can be put back to the duct. Transportation and Storage 1) 胶带在运输过程中防曝晒、防雨淋、防止压坏变形 Keep tape away from insolation,rain,or pressing. 2 在运输或贮存中受到 5以下暴冻时，需在 20左右存放 48 小时，方可施工 If it has been stored or transported in the temperature below 5，it has to be put in the place at about 20 for 48hours before it is installed. 3)The storage time is 12 months.It should be kept in a cool place at530，75，away from heat or open fire
