The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art in a specific case.

The invention will be described in detail below with reference to the drawings in connection with embodiments.

The sea pipe heat preservation node sheath, as shown in figures 1 to 6, comprises a heat preservation body 1, wherein a protection layer 2 is coated outside the heat preservation body; the heat preservation body comprises a main body 3, butt joints matched with each other are arranged on two sides of the main body, and deformation grooves 4 are formed on the other two sides of the main body; wherein, first butt joint 5 is equipped with towards the first recess 6 of heat preservation body surface, and second butt joint 7 is equipped with towards the second recess 8 of heat preservation body internal surface, and the tank bottom surface of first, second recess is inclined plane 9, because the tank bottom is the inclined plane, when this sheath of installation, the laminating is inseparable between the two easier assurance when two butt joints overlap joint, and heat preservation performance is ensured. The sheath forms a lap joint 10 at (the outer surface of) the end of the first butt joint, the lap joint (in the longitudinal direction) covers at least the second butt joint, and the inner surface of the lap joint is bonded to the outer surface of the second butt joint. Preferably, the overlap joint portion that the sheath formed at the terminal of first butt joint, with the sheath on the heat preservation body be integrated into one piece structure, easily production preparation, and structural reliability is good, and stability is high.

In general, two ends of the deformation groove extend to the lap joint parts at two sides respectively, and the depth of the deformation groove is generally 1/3-2/3 of the thickness of the heat insulation layer body. The heat preservation body of aerogel material itself has a small amount of deformability, and the deformation groove of design in addition can be when this sheath is installed in pipeline node department, through extrusion deformation, and the transition structure of the junction between the better adaptation node department pipeline makes heat preservation body and pipeline surface laminating degree higher, and promptly, heat preservation body tip and node transition structure position laminating area are bigger, and heat preservation performance is more ensured.

Typically, the insulation body is made of aerogel material. The protective layer is made of silicon-titanium alloy cloth. As an example, the heat-insulating layer body is made of silica aerogel felt, has low heat conductivity, certain tensile strength and compression strength and excellent heat-insulating performance, and compared with the common heat-insulating material used for heat-insulating pipes in the prior art, the heat-insulating layer made of the aerogel material has better heat-insulating performance, so that the thickness of the heat-insulating layer made of the aerogel material can be made smaller, and the volume of a pipeline is saved.

The outer surface of the heat-insulating layer body and/or the outer surface of the protective layer are provided with a plurality of binding grooves 11. The stainless steel wire or the galvanized steel wire is bound in the binding groove, so that the sheath is fixed, the steel wire is not easy to fall off, the firmness is high, the reliability is good, and the scratch-resistant and wear-resistant coating can be coated on the surface of the binding groove. In addition, can be equipped with the self-adhesion area at overlap joint portion internal surface, when this sheath is installed to pipeline node department, after the sheath twines a week around pipeline node department, directly paste overlap joint portion to the surface of the other end, then rethread steel wire carries out the ligature, convenient operation is swift, need not to take place to drop when worrying the construction, labour saving and time saving, single can operate.

When the heat preservation at the pipeline joint is constructed, the sheath is directly wrapped at the joint, two pairs of joints are combined to realize butt joint of two ends of the sheath, then the lap joint is directly lapped on the outer side of the second lap joint, the lap joint and the other end of the sheath are directly adhered in the scheme that self-adhesive tapes are designed on the lap joint, and then the sheath is bound through steel wires. The sheath is manufactured according to the length of the pipeline at the joint, and can be directly wrapped and fixed to finish construction operation during construction, so that the sheath is very simple and convenient, the construction operation efficiency is high, and the heat preservation performance is guaranteed.

The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
