Heat Shrink wrapping is a two-component solvent-free liquid epoxy primer + radiation cross-linked polyethylene mending tape (sets) + adhesive layer composed of three layers structure, which is called the three PE external corrosion coating. Substrate selection of The Dow Chemical Company (Dow Chemical Co.) quality DFDD 0588 BK LDPE, after radiation engineering performance is better than Japan's Ube UBEC 600V6, is the material of choice for heat shrink products; adhesives used in Japan's Mitsui EVA, dozens of high-temperature chemical materials, additives Russia butyl rubber, natural rubber, rosin resin refining. Heat shrinkable fill the mouth with the late nineties used in the oil and gas industry, long-distance transport of oil, gas pipe weld corrosion, but also widely used in the beginning of this century, long-distance oil and gas pipe weld corrosion, city gas pipeline network seam corrosion , heating pipe seam corrosion, water pipe joints and other areas of corrosion. Heat shrinkable fill the mouth with a steel pipe weld corrosion coating designed with separate sets of fixed pieces, shrinking mending tape is made of radiation crosslinked polyolefin substrates and special hot melt adhesive sealing compound formed at high temperatures This new type of heat shrinkable mending materials with high mechanical strength, stable performance, anti-aging, corrosion-resistant chemical seal adhesive power, easy to operate and so on. Heat shrinkable fill the mouth with antiseptic industry called to live in the sleeve, the relative heat shrinkable sleeve is called dead muzzle terms, in addition to the main heat shrinkable mending tape, strip and comes with tabs, and fill the mouth with heat shrinkable to facilitate large-scale production, construction is also a lot easier. ? To ensure easy on-site construction company, provide for each channel individually weld a small package, there are AB two-component solvent-free epoxy paint, brushes, mixing sticks, plastic disposable gloves while package for certification, operating instructions, to ensure construction quality and construction schedule. Accessories primer Description: 3PE preservative shrinkable mending tape comprises two component epoxy primer and accessories, 2PE heat shrinkable corrosion mending with matching accessories and paint without the use of units: Oilfield, Shengli Oilfield, Liaohe Oilfield, Hebei East oil fields, Huabei Oilfield, Jiangsu Oilfield, Jilin Oilfield, Changqing Oilfield, PetroChina and Sinopec oil and gas transmission pipelines and depots, the city built and repair of gas pipelines.
