In order to achieve the above purpose, the utility model provides a following technical scheme: an anticorrosive heat-insulating steel pipe comprising: the pipeline, the fixed cover that has cup jointed the cross-section and be the hexagon of the outer wall of pipeline, the inside packing of heat preservation has the heat preservation, the top of heat preservation is provided with the upper shield, the outer wall bonding of upper shield has the sealing washer, the four corners department of upper shield runs through and has inserted the gim peg.

Preferably, the pipeline and the heat insulation sleeve are of an integral structure, and epoxy resin paint is coated on the surfaces of the pipeline and the heat insulation sleeve.

Preferably, the top of the heat insulation sleeve is provided with a filling opening with a T-shaped section, and the four corners of the filling opening are internally provided with threaded holes.

Preferably, the heat-insulating layer is made of glass wool.

Preferably, the size of the sleeve cover is matched with the size of a filling opening formed in the top of the heat-insulating sleeve.

Preferably, the sealing ring is made of rubber.

Preferably, the fixing bolt penetrates through the four corners of the sleeve cover and is in threaded connection with threaded holes formed in the four corners of the filling opening.

Compared with the prior art, the beneficial effects of the utility model are that:

1. through mutually supporting between upper shield, sealing washer and the gim peg for when rotating the gim peg, can take off the upper shield from the insulation cover, thereby conveniently open the inside of insulation cover, so that change the insulation layer.

2. The hexagon through the insulation cover sets up for when the pipeline is placed and is under construction the welding on the ground, the difficult condition that deflects that takes place, thereby do not need the individual to support and just can accomplish the butt joint installation between the pipeline.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: an anticorrosive heat-insulating steel pipe comprising: pipeline 1, pipeline 1's outer wall is fixed to be cup jointed the cross-section and is hexagon insulation cover 2, setting through the hexagon, make pipeline 1 difficult emergence when placing deflect, structure as an organic whole between pipeline 1 and the insulation cover 2, and pipeline 1 and insulation cover 2's surface all scribbles the epoxy paint that has, the epoxy paint has stronger adhesive force, the chemical resistance, the corrosion resistance, the water proofness, thermal stability and good electrical insulation nature, the fill opening that the cross-section is "T" shape is seted up at insulation cover 2's top, and the inside screw hole that has all seted up in four corners of fill opening, insulation cover 2's inside packing has heat preservation 3, heat preservation 3 is the cotton material of glass, the cotton chemical composition of glass belongs to the glass class, be an inorganic fibre, it is good to have the shaping, small volume density, the thermal conductivity is low, thermal insulation, sound absorption performance is good, corrosion-resistant and chemical behavior stable characteristics, insulation cover 2's top is provided with upper shield 4, the size of fill opening size looks adaptation that the top was seted up of upper shield 4 and the heat preservation 2 top was seted up, the outer wall of upper shield 4 bonds there is sealed, the outer wall of upper shield 4 has sealing washer 5, make the fixed cover 4 and the plug of the fixed connection of cover 4 of four corners through the internal thread of the corner, thereby it is convenient for the change, it ties to insert the four corners, it ties to carry out the internal bolt to the corner of the fixed connection of the internal connection of cover 4, thereby it is convenient for the four corners to insert the internal connection of the internal bolt, it is convenient for the four corners between the insulation cover 4, it is convenient for the insulation cover 2, it is to change, it is convenient for the four corners to change four corners, it is convenient for the internal bolt to change four corners to insert the internal bolt, it is convenient for the internal bolt to insert the internal bolt, it is to insert the insulation cover 4, it is convenient for the insulation cover 4, it is to change four corners to change.
