Steel casing (steel jacket) embedded technology is a waterproof, leakproof, impermeability, compressive and fully enclosed laying of new technology, is burying technology used in areas with high water table, a large-break. It is composed of the transmission medium pipe, seamless carbon steel pipe and steel pipe and anticorrosion coat jacket filled with fine steel wool between the combination can also be used graphite, calcium silicate tiles shell filled with polyurethane foam and composite.
One is by the transmission medium steel pipe, steel pipe and anticorrosion coat jacket filled with fine steel wool between the combination can also be used graphite, calcium silicate tiles shell filled with polyurethane foam and composite. Steel casing (steel jacket) embedded technology is a waterproof, leakproof, impermeability, compressive and fully enclosed laying of new technology, is burying technology used in areas with high water table, a large-break. Protective tube buried pipe water tight primary problem is the reliability, in addition to have a good mechanical strength, high strength steel casing as welded connections, the waterproof reliability is very high sealing performance, in addition, its high temperature performance is other outer protection tube can not be compared. In areas with high groundwater level, in order to ensure groundwater does not affect the normal operation of the steam buried pipe, outer protective layer is preferably made of sturdy, sealed steel casing.
