Abstract
The utility model relates to a ceramic heat preservation seamless steel tube which comprises a seamless steel tube base body, a ceramic layer and a seamless steel tube outer protection tube. Protruding ribs are arranged on the outer surface of the seamless steel tube basal body, protruding ribs are arranged on the inner surface of the seamless steel tube outer protection tube, the protruding ribs on the outer surface of the seamless steel tube basal body and the protruding ribs on the inner surface of the seamless steel tube outer protection tube are arranged in a staggered mode, the seamless steel tube outer protection tube is coated with an organic silicon resin high-temperature-resistant thermal insulation layer and sleeved with a stainless steel heat reflection tube, and a ceramic fiber heat preservation layer is poured in the space between the stainless steel heat reflection tube and the seamless steel tube outer protection tube. The ceramic heat preservation seamless steel tube has the advantages that mechanical properties, especially the pressure-resistant property, of the steel tube are improved through the ceramic layer in the middle under the high temperature condition, meanwhile, heat radiation is prevented because of low thermal conductivity of the ceramic layer, and the heat preservation effect is further improved through the stainless steel heat reflection tube and the ceramic fiber heat preservation layer.
Description
Technical field
The utility model relates to a kind of ceramic thermal insulation seamless steel pipe.
Background technique
Seamless steel pipe is structural strength under high temperature condition, and shock resistance will variation, in the time of transferring high voltage high temperature media, for satisfying the demand, need to use special steel material, and needs larger thickness.And clean steel material steel pipe heat insulation effect is poor, very easily loses heat in course of conveying.
Model utility content
Technical problem to be solved in the utility model is: a kind of ceramic thermal insulation seamless steel pipe is provided, and high insulating effect, and under high temperature condition, still have good mechanical property.
The utility model solves the technological scheme that its technical problem adopts: a kind of ceramic thermal insulation seamless steel pipe, comprise seamless steel pipe matrix, ceramic layer, the outer pillar of seamless steel pipe, outer surface at seamless steel pipe matrix has convex tendon, outside seamless steel pipe, on the internal surface of pillar, there is convex tendon, the convex tendon of seamless steel pipe outer surface of matrix, be crisscross arranged with the convex tendon of seamless steel pipe matrix internal surface, outside seamless steel pipe, on pillar, apply organic siliconresin high temperature resistant heat insulation layer, the outer pillar outer casing stainless steel heat reflection pipe of seamless steel pipe, cast ceramics fiber insulation layer between pillar outside stainless steel hot reflection tube and seamless steel pipe.
Internal surface at seamless steel pipe matrix applies low pressure polyethylene anticorrosive coat, applies one deck organic siliconresin high temperature resistant heat insulation layer outward at low pressure polyethylene anticorrosive coat.
The beneficial effects of the utility model are: middle ceramic layer is in the mechanical property improving under steel pipe high temperature condition, particularly when withstand voltage properties, by its low-thermal conductivity, prevent the radiation of heat, further improve heat insulation effect by stainless steel hot reflection tube and ceramic fiber thermal insulation layer simultaneously.
