Abstract
The utility model discloses an electrically heated insulating pipe, which solves the problem on how to deliver high-viscosity medium. The electrically heated insulating pipe is characterized in that a plurality of electric heating wires are evenly laid on the outer wall of a steel pipe, and are sequentially wrapped by a heat-conducting film, an anti-corrosion adhesive tape, an insulating layer and a waterproof sheath. The heat-conducting film transfers the temperature of the electric heating wires to the pipe wall, so that the temperature of the pipe wall is uniform, and the heat-conducting film can also prevent the local over-high temperature and over-fast aging of the electric heating wires, so that the service life can be prolonged. Heat is gathered in the insulating layer to form a thermal field, so that the thermal efficiency can be sufficiently exerted. The electrically heated insulating pipe is easy and convenient to mount, and can be widely used in the fields of petroleum, chemical and the like.
Description
Affiliated technical field
The utility model relates to a kind of conveyance conduit, belongs to the electrical heat tracing pipe.
Background technique
Conveyance conduit has various forms according to the character of fed sheet of a media, and at oil, chemical field, often stickiness is higher for medium under the normal temperature, and is mobile poor, and at 38 ℃, carry just very difficult winter as condensation point of crude oil, and the back crude oil of heating is in liquid state just can smooth delivery of power.In other field, also exist the transportation problem of high viscosity medium, generally all take the way that heats.Existing heating pipe is taked water companion's heat or steam tracing, cost height, complex process mostly.
The model utility content
The purpose of this utility model is exactly to provide a kind of electrical heat tracing pipe for the transportation problem that solves high viscosity medium.
The utility model is achieved through the following technical solutions: the electrical heat tracing pipe, form by steel pipe, feed cable and electrically-heated-wire, evenly lay many electrically-heated-wires on the outer wall of steel pipe, electrically-heated-wire wraps up heat conducting film and anticorrosion adhesive tape outward successively, three feed cables of anticorrosion adhesive tape appearance tiling, feed cable wraps up thermal insulation layer and waterproof crust outward successively, and tarpaulin is equipped with at the steel pipe two ends, and feed cable and electrically-heated-wire all pass tarpaulin.
The beneficial effects of the utility model are:
This electrical heat tracing pipe, owing to wrap up heat conducting film and anticorrosion adhesive tape successively outside electrically-heated-wire, thereby it is even to have a tube wall temperature, high and life-span of the thermal efficiency such as grows at outstanding advantage.Heat conducting film can be given tube wall with the temperature transfer of electrically-heated-wire, makes the temperature of the tube wall temperature of electrically-heated-wire interval region near electrically-heated-wire on the one hand, makes tube wall temperature even, helps medium transport; Can as soon as possible the temperature transfer of electrically-heated-wire be gone out on the other hand, avoid the electrically-heated-wire local temperature too high, accelerate aging, thereby electrically-heated-wire is worked all the time at a lower temperature, increase the service life.Behind the parcel thermal insulation layer, can be in thermal insulation layer heat accumulation, the temperature that makes electrically-heated-wire and tube wall is brought into play the thermal efficiency to greatest extent not to external diffusion.This electrical heat tracing pipe, the moulding that is prefabricated in the factory is collection heating, insulation, anticorrosionly is the novel gathering line of one that every pipeline is the heating unit of an independent sealed insulation, site operation has advantages such as simple installation, high insulating effect.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among Fig. 1,1. electrically-heated-wire, 2. feed cable, 3. steel pipe, 4. tarpaulin, 5. anticorrosion adhesive tape, 6. heat conducting film, 7. thermal insulation layer, 8. waterproof crust.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
By shown in Figure 1, the electrical heat tracing pipe, form by steel pipe 3, feed cable 2 and electrically-heated-wire 1, evenly lay many electrically-heated-wires 1 on steel pipe 3 outer walls, electrically-heated-wire 1 outer heat conducting film 6 and the anticorrosion adhesive tape 5 of wrapping up successively, three feed cables 2 of anticorrosion adhesive tape 5 appearances tiling, feed cable 2 outer thermal insulation layer 7 and the waterproof crusts 8 of wrapping up successively, tarpaulin 4 is equipped with at steel pipe 3 two ends, and feed cable 2 and electrically-heated-wire 1 all pass tarpaulin 4.
During use, the feed cable 2 of adjacent electrical heat tracing pipe is connected respectively with electrically-heated-wire 1, by link feed cable 2 and electrically-heated-wire 1 is communicated with again, realize giving the purpose of electrically-heated-wire 1 power supply, after the whole piece pipeline is communicated with, become the electrical heat tracing pipeline completely.As required, determine to lay the quantity of electrically-heated-wire 1, can control line temperature, guarantee the safe transport of high viscosity medium.
