三 使用方法：
(1)、钢管表面处理：除锈、除焊渣、毛刺、油、污物并保持清洁干燥。手工除锈应达St3级，机械除锈应达到Sa2级，并符合SYJ4 0 0 7—8 6要求。
(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)、胶带在运输过程中防曝晒、防雨淋、防止压坏变形。
(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)、应在阴凉，温度5～30℃，温度＜75℃库房中存放，储存期12个月，并远离热源与明火。

Polypropylene fiber anticorrosive tape
(Pipeline corrosion protection tape.PP tape. PP enhanced fiber tape)
Purpose & Features:
Anticorrosive polypropylene fiber tap is a new kind of pollution-free and nondestructive product . representing the top level of cold-wrapping tape both at home and abroad and called and c ”anticorrosion champion ”it can be widely used in such anticorrosive constructions as water supply ,steel pipelines for conveying oil ,natural gas and coal gas or underground tank outer anticorrosion or rehabilitation work in oil ,natural gas ,chemical engineering and municipal constructions it is the appointed product replacing asphalt glass cloth and epoxy coal tar by the National Construction Department and Environmental Protection General Bureau .The product is characterized by its easy construction ,shock resistance, aging resistance elongation resistance ,ultra-violet light resistance and high bond strength .
The basis material of the unique modified polypropylene knitted fabrics ,adopting modified butyl rubber asphalt as anticorrosive rubber ,its fabric structure can effectively resist the creep fracture due to the soil stress. Aging test shows that it can endure 50 years of corrosion ,the index of which overpasses that of the SY/T0414-2007 standard .it is the best and the most economic choice .
