Insulation pipe is the abbreviation of insulation sleeve. Insulation pipe is used for the transportation of liquid, gas and other media. It is used in the insulation engineering of petroleum, chemical, aerospace, hot spring, military, central heating, central air conditioning, municipal and other pipelines. Insulation pipe is suitable for conveying all kinds of media in the range of - 50 ~ 150 ℃. It is widely used in central heating, cooling and hot oil transportation, as well as in warm room, cold storage, coal mine, petroleum, chemical and other industries. In some mines, it is often necessary to use insulated pipes to transport minerals with higher temperature. Due to the high temperature at the bottom of the mine, the ordinary insulation pipe is easy to deform and even leak due to the insufficient high temperature resistance.

     The high temperature insulation pipe is made of ceramic fiber material. It has good high temperature resistance and corrosion resistance. It can effectively protect the outer casing pipe and is suitable for use in mine. The high temperature insulation pipe includes a circular tube, and the outer wall of the work pipe is successively provided with aluminum silicate layer, drag reduction layer, microporous calcium silicate layer, heat insulation layer and aluminum foil reflection layer. The outer wall of the insulation layer is wrapped with a circular tube shaped outer wall, and the outer wall of the outer wall of the outer pipe is coated with an outer heat-resistant layer, the working pipe, the aluminum silicate layer The ends of the drag reduction layer, microporous calcium silicate layer, heat insulation layer and aluminum foil reflector are aligned. The two ends of the insulation layer, outer sleeve and outer heat-resistant layer are all aligned. The end of the working pipe, aluminum silicate layer, drag reduction layer, microporous calcium silicate layer, heat insulation layer and aluminum foil reflector are staggered with the end of the insulation layer, outer sleeve and outer heat-resistant layer by about 1 m.

      The working pipe and outer sleeve are made of high temperature resistant rubber materials. Aluminum silicate layer is made of aluminum silicate insulation material. The drag reduction layer is made of high temperature resistant fiber felt. The microporous calcium silicate layer is made of asbestos free microporous calcium silicate material. The insulation layer is made of aerogel felt material. The outer heat resistant layer is made of ceramic fiber materials.

      The high temperature insulation pipe is provided with working pipe, aluminum silicate layer, drag reducing layer, microporous calcium silicate layer, heat insulation layer, aluminum foil reflection layer, heat insulation layer, outer heat-resistant layer and outer heat-resistant layer. The inner insulation layer and the insulation layer have good thermal insulation performance, while the aluminum foil reflector can effectively reduce radiation heat dissipation. The outer heat resistant layer is made of ceramic fiber material, which not only has good high temperature resistance, but also has good corrosion resistance. It can effectively protect the outer casing pipe and is suitable for use in mine.
