In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustration and not for limitation of the present invention.
As shown in figure 1, a thermal stability anticorrosion steel pipe, including steel pipe body 1, the outer cladding of steel pipe body 1 has epoxy layer 2, epoxy layer 2 is provided with the buffer layer outward, the buffer layer is provided with insulating layer 4 outward, insulating layer 4 is provided with polyethylene layer 5 outward, the buffer layer is the elastic adhesive tape 3 of spiral winding on steel pipe body 1. This application forms certain shock attenuation space and thermal-insulated space between different levels when realizing the adhesion between the different levels through adopting elasticity adhesive tape 3, makes anticorrosive steel pipe when possessing anticorrosive ability, still possesses thermal stability and shock resistance.
Furthermore, the spirally wound elastic rubber strip 3 and the heat insulation layer 4 form a spiral shock absorption space. The elastic rubber strips 3 form a damping space with the upper layer and the lower layer which are adhered to each other respectively, and the air in the damping space can also play a role in heat insulation due to poor heat conductivity of the air. The spiral winding elastic rubber strip 3 is convenient and rapid to produce, and the production efficiency of enterprises is improved.
Furthermore, the shock absorption layer and the heat insulation layer 4 are sequentially arranged at intervals in two layers. The two layers of shock absorption layers and the heat insulation layer 4 are sequentially arranged, so that a heat insulation space is further formed between the two layers of heat insulation layers 4, the outside is fully isolated from the fluid in the steel pipe, the external temperature does not influence the internal fluid, the thermal stability function of the steel pipe is realized, the main anticorrosion functional layer, namely the epoxy resin layer 2, outside the steel pipe is particularly prevented from being damaged by external heat, and the stability of the anticorrosion basic function of the steel pipe is ensured.
Furthermore, the spiral directions of the elastic rubber strips 3 of the two shock absorption layers are opposite. The elastic rubber strips 3 with opposite spiral directions are arranged in a staggered mode to form a mutually-interwoven mesh structure, and the mesh structure can enhance the stability of the outer-layer coating material.
Furthermore, the screw pitches of the elastic rubber strips 3 of the two shock absorption layers are the same. The net structure formed by two reverse spirals with the same pitch is more stable.
Further, the elastic rubber strip 3 is a hot-melt rubber strip. Adopt hot melt adhesive tape, directly realize in the real-time cladding of steel pipe body 1 outside through rotating steel pipe body 1 at the uniform velocity during production, production technology is simple, very big improvement production efficiency.
Further, the heat insulation layer 4 and the polyethylene layer 5 are bonded through composite glue. The stability of the connection structure of the heat insulation layer 4 and the polyethylene layer 5 is ensured by the composite adhesive, and the composite adhesive in actual production is preferably polyvinyl alcohol environment-friendly adhesive.
Further, the outer layers of the end parts of the two sides of the steel pipe body 1 are sealed. The end sealing is arranged, so that a damping layer can form a sealed damping space and a heat insulation space, and the problem that the thermal stability fails due to the fact that temperature airflow changed by the end enters the space is avoided.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
