Steel sleeve steel composite insulation tube is a kind of buried pipeline in the no, can also be buried concrete structure in the case of way, namely working pipe thermal expansion in the outer tube, thus reducing the material cost, shortening the construction date, and ensure the safety of heating pipeline, and can be widely application of safer in different temperature, especially suitable for high temperature steam pipeline project. Using the temperature can reach 150 ℃ -450 ℃. The port of the pipeline is generally used in polyethylene film or the three layer PE entangled with cold sealing, prevent the installation or construction into the moisture or water. Heat preservation material multi-layer overlapping bandaging, effectively reduce the heat loss, while in the outer surface of control measures, prevent cold bridge, so that the temperature control coat anticorrosive layer is guaranteed. Insulating materials used in aluminum foil wrapped multi-layer reflective layer, reduce the heat loss, so that the steam pipeline of more economic and reasonable. Drainage system adopt totally closed form, flexible layout, reasonable structure, safe and reliable. Steel casing on the moisture removal pipe can timely discharge of wet gas, but also can be used as a warning signal of daily operation of the tube. The heat compensation pipe is made of high quality corrugated pipe compensator, which is arranged in the casing, a buried form, without setting the observation well, convenient construction, short construction period. Suitable for conveying 2.5MPa, steam 350 degrees Celsius or other medium, the product by using steel pipe for the outer protective layer, has high strength, not easy to damage, construction and maintenance is convenient, the advantages of long service life.
