Huayi buried pipeline closed heat shrinkable sleeve

Heat shrinkable sleeve is closed by the radiation crosslinked polyolefin composite substrate and special seals made of hot melt, which has excellent hot melt adhesive properties with steel bottom and pipe coating such as polyethylene, polypropylene, ring oxygen powder, epoxy coal tar, etc. to form a good seal protection (can be taken at low difficulty brushing Preheat high performance primer to get good results), hot melt adhesive and polyethylene base, steel surfaces and solids epoxy coating can form a good bond (three PE preservative), heat shrinkable sleeve closed, the grassroots contraction layer melts, close up mouth coated shrink, shrink sleeves closed with the original pipeline coatings to form a solid, continuous corrosion body. Because it is a closed tubular-shaped cap, seamless straight pipe structure, so before pipe welding, pipe welding must first set to the next seam weld to be completed, and then back to the welding seams baking, otherwise after welding can not be set to go, and this is more obvious and shrinking mending with one difference. Radiation cross-linked polyethylene shrink sleeve and shrink shrinking band than different, and radiation cross-linked polyethylene heat shrinkable sleeve is a cylindrical one-piece, using a higher safety factor, the better.
