Abstract
The utility model provides a continuously reinforced plastic composite pipe with heating function. The utility model is characterized in that the composite pipe body mainly comprises an internal layer, a heating resistance layer, an enhancement layer, and an external protective layer to form a laminate structure. The both ends of the heating resistance layer are provided with conductive wire connecting terminals which are connected with a heating power supply. The heating resistance layer is selected from one or more structural forms of a netted resistance wire, an electrothermal thin film, a twining electrothermal band, etc. The conductive wire connecting terminals are selected from the structure of metallic a conducting ring and a metallic wiring terminal. The utility model can collect and deliver crude oil, water, gas, etc. by a single pipe. Thus, the cost of manufacture of the conveying pipeline is reduced, and the conveying cost is saved. In addition, the utility model can be used to heat and deblock a frozen pipeline, and thus, the problems of the coagulation and the freeze of pipes are solved.
Description
Technical field:
The utility model provides a kind of continuous reinforced plastic composite pipe with heating function, relates to oil pipeline, is used to carry the pipeline of liquid, gas material, belongs to stratiform multiple tube technical field.
Background technique:
At present, the Oilfield Pipelines major part is materials such as the nonmetal multiple tube transferring oil, gas, water with metallic conduit or small part, particularly when carrying the high crude oil of stickiness, must adopt and mix hot delivery technology, and conveying engineering involves great expense, the oil transportation cost increase.Because fed sheet of a media and field produces environment is abominable, metallic conduit is very easy to be corroded, and causes the run, drip, leak phenomenon in oil field serious, befouling environment, and cause serious security incident such as fire easily.Though, developed compound reinforced pipes such as glass fibre enhancing, Steel Skeleton enhancing, solved the material corrosion and waited some problems, but be difficult to solve for the de-plugging of nonmetal pipeline, problem such as thaw, thereby, restricted nonmetal multiple tube promoting the use of in the oil field.
Summary of the invention:
The purpose of this utility model provides a kind of continuous reinforced plastic composite pipe with heating function, has solved the de-plugging when conveying crude oil of nonmetal pipeline, problem such as thaw.
Technical solution of the present utility model is as follows: the composite pipe body mainly constitutes stratiform structure by internal layer, heating resistor layer, enhancement layer and outer protection layer; Being provided with the conductive connection terminal at the two ends of heating resistor layer is connected with heating power supply.
Described heating resistor layer is selected from one or more structural type such as ribbon heater of netted resistance wire, electric-heating thin film, winding.
The conductive connection terminal comprises that metallic conduction ring, metal connection post etc. are used for the device that lead connects.
On the basis that guarantees heating resistor layer structure of the present utility model, between internal layer, heating resistor layer and the outer protection layer, can combination in any increase enhancement layer, adhesive layer and decorative layer according to requirement of engineering.
Good effect of the present utility model is: adopt the heating resistor layer structure in the composite pipe body, by heater body the medium of carrying in the pipeline is heated up, be convenient to media flow, prevent line clogging.The utility model can be realized media such as single tube collection output oil, water, gas, has reduced the transfer line cost, has saved the conveying cost.In addition, can heat de-plugging, solve pipe, the frozen pipe difficult problem with fixed attention of conveyance conduit for the pipeline that freezes.
