Heat shrinkable sleeve mending

Heat shrinkable sleeve mending corrosion status of the pipeline? According to the survey, in our pipeline accident, caused by corrosion damage accounts for about 3O%. Several oilfield east of various types of pipes due to corrosion perforation up to 2 million times? / Year,? 400 km pipeline to replace the quantity / year. Natural Gas Pipeline, May 1971 - May 1986 15 years ask? Explosion and fire accidents due to corrosion caused by up to 83 cases, economic losses amounting to more than 600 million yuan. 1993 Year in Zhongyuan Oilfield production system due to corrosion generated economic losses of 1.6 billion yuan. Economic losses of China's petrochemical industry in 1989 due to corrosion caused about 20 billion yuan. Pipe coating heat-shrinkable sleeve is a new easy-to-good performance anti-corrosion steel pipe weld material. The substrate and the hot melt adhesive layer is composed of two layers materials. The substrate is a polyethylene material by extrusion, radiation crosslinking, stretching plastic sleeve formed? (Sheet). Hot melt adhesive is a special adhesive. They are solid at room temperature. Heated molten state can flow, can be coated on a substrate. Metals and plastics have good adhesion. Steel external coating is usually three-layer structure? (Also known as three-tier PE preservative). And anti-corrosion coatings for steel in contact primer. The middle of the hot melt adhesive. The outermost layer of crosslinked polyethylene. Few cases taken to the second floor steel external coating? (Layer PE preservative), and steel contact sealing hot melt adhesive, the outer layer of crosslinked polyethylene. Huayi shrink the company after years of development and research of steel pipe anti-corrosion heat shrink material, the existing leading products: polyethylene heat shrinkable tape, pipeline corrosion heat shrink, shrink wrapped tape, polyethylene tape wrapped around the cold, heat-shrinkable waterproof cap, covering film, Mending rods, epoxy coatings and other products. Products are mainly used for corrosion protection of buried and aerial weld steel pipe, pipe, fittings, flanges, pipelines and other parts of the locking clips can also be used to fill the entire root estuary anti-corrosion protection of steel and pipe insulation. Suitable for 2PE, 3PE, FBE, epoxy coal tar pitch and enamels for pipeline weld mending corrosion, corrosion elbow region and outer anti-corrosion and heat pipe body oil seal mending.
