Description
Technical field
This utility model relates to a kind of fluid-transporting tubing, is specifically related to a kind of composite material tube with self heating function.
Background technology
The problem that existing oil field crude oil transmission heating furnace generally exists corrosion and scaling.Corrosion makes furnace binding intensity decline, and fouling then affects heat transfer efficiency and conveying power, and the phenomenon that plugging causes stove to explode even can occur when fouling is serious.Therefore, corrosion and fouling directly influence operation safety and the heat exchange efficiency of heating furnace, and have increased considerably operating cost.
Tracing it to its cause, the heat exchanger components of existing oil field crude oil transmission heating furnace uses metal tube, is crude oil and the sewage of flowing, is pyrotechnics or heated heat exchanging liquid outside metal tube inside metal tube.Dirt all can be formed along with running the inside and outside wall of time metal tube, the encrustation of metal tube is even more serious by contrast, because containing being corrosive calcium and magnesium plasma in the composition of crude oil and sewage, these compositions in metal tube in flow process interact produce carbonate, calcium sulfate, silicate absorption on inwall, form hard dirt, outer extension, inwardly promoting inner wall of metal tube corrosion tube wall strength, outside dirt is the most long-pending more thick increases the weight of thermal resistance.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of composite material tube with self heating function, and it can avoid inboard wall of tube body fouling.
For solving above-mentioned technical problem, this utility model has the technical solution of the composite material tube of self heating function and is:
Including thermoplastic inner liner, reinforcing fiber structure sheaf, thermoplastic external protection coating, reinforcing fiber structure sheaf is arranged between thermoplastic inner liner and thermoplastic external protection coating；Thermoplastic inner liner be internally formed tube cavity, as the flow channel of medium；Reinforcing fiber structure sheaf, as the supporting construction of body compressive resistance, has insulated heat function simultaneously；Thermoplastic external protection coating is as insulated thermal insulating layer；Reinforcing fiber structure sheaf and thermoplastic external protection coating by temperature in pipe with manage outer temperature and completely cut off and opens, prevent extraneous temperature conduction in body and prevent from managing the loss of interior temperature；It is provided with many heating wires in thermoplastic inner liner, can heat up after heating wires energising；Temperature after heating wires is heated up by thermoplastic inner liner is transmitted to tube cavity, thus heats the flow media in body, it is achieved self heating function.
Described reinforcing fiber structure sheaf uses carbon fiber, glass fibre or aramid fiber.
Described thermoplastic external protection coating uses thermoplastic.
Described thermoplastic external protection coating uses politef.
Described thermoplastic inner liner uses Heat Conduction Material.
Described thermoplastic inner liner uses PVDF or modified Teflon.
What this utility model can reach has the technical effect that
This utility model has excellent ant-scaling, resistive connection wax performance, is applied in the crude oil transmission heating furnace of oil field, it is possible to the problem fundamentally solving corrosion and scaling.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is the schematic diagram that this utility model has the composite material tube of self heating function.
Description of reference numerals in figure:
1 is thermoplastic inner liner, and 2 is heating wires,
3 is reinforcing fiber structure sheaf, and 4 is thermoplastic external protection coating.
Detailed description of the invention
As it is shown in figure 1, this utility model has the composite material tube of self heating function, including thermoplastic inner liner 1, reinforcing fiber structure sheaf 3, thermoplastic external protection coating 4, reinforcing fiber structure sheaf 3 is arranged between thermoplastic inner liner 1 and thermoplastic external protection coating 4；Thermoplastic inner liner 1 be internally formed tube cavity, as the flow channel of medium；
Reinforcing fiber structure sheaf 3, as the supporting construction of body compressive resistance, has insulated heat function simultaneously；Reinforcing fiber structure sheaf 3 can use carbon fiber, glass fibre or aramid fiber；
Thermoplastic external protection coating 4 is as insulated thermal insulating layer；Reinforcing fiber structure sheaf and thermoplastic external protection coating by temperature in pipe with manage outer temperature and completely cut off and opens, prevent extraneous temperature conduction in body, so that tubular body is not affected by ambient temperature, prevent from managing the loss of interior temperature simultaneously；Thermoplastic external protection coating 4 can use resistant to elevated temperatures thermoplastic, such as politef；
It is provided with many heating wires 2 in thermoplastic inner liner 1, can heat up after heating wires 2 energising；Thermoplastic inner liner 1 uses Heat Conduction Material, such as PVDF Kynoar, modified Teflon etc.；
In many heating wires 2 fixed packet are wrapped in by thermoplastic inner liner 1, heating wires 2 is through along the length direction (the most axial) of body；Many heating wires 2 are uniformly distributed along the circumference of body；
Temperature after heating wires 2 is heated up by thermoplastic inner liner 1 is transmitted to tube cavity, thus heats the flow media in body, it is achieved self heating function.
This utility model can carry crude oil under high temperature and high pressure environment, and during crude oil flows in body, heated wire 2 heats, it is possible to avoid inboard wall of tube body fouling.
