A steel pipe insulation manufacturers, steel pipe insulation sleeve steel prices, steel pipe insulation sleeve Hebei Steel Standard: Contact: 13731709385 QQ: 929166756 CJ / T104 --- 2005 "urban heating buried steam pipe Technical Specification" one kind by the transmission medium steel, corrosion and superfine wool coat steel pipe and the jacket pipe is filled between the combination may also be used graphite, silicon calcium shell and filled with polyurethane watt bulb technology is Buried in the water table a major breakthrough high use areas. The primary issue of the protection tube buried pipeline is tight waterproof reliability, in addition to have good mechanical strength, high strength steel casing due to the use of welded connections, waterproof sealing performance steel sleeve reliability is very high. In addition, its high temperature Performance also other outer protection tube can not be compared. In areas of high water table, in order to ensure the normal operation of the steam does not affect groundwater buried pipe, outer protective layer is preferably made of sturdy, sealed steel casing.
