Abstract
The utility model relates to an antisepsis thermal pipe with non-metallic electroheat fiber heating, which comprises an external protection layer and an protection layer, and a non-metallic electroheat fiber heating layer under the external protection layer. The two ends of the electroheat fiber in the heating layer are connected with the cable of power source; seamless steel tubes whose external walls are applied with thermal insulation and antisepsis paint are set under the electroheat fiber heating layer; antisepsis paint is applied in the internal wall of the seamless steel tubes. This utility model has the advantages of excellent antisepsis and thermal efficiency, which can reduce the deposition of crude oil in the tube wall and lower down the dynamic friction resistance of fluid.
Description
Technical field
The utility model relates to a kind of anti-corrosion heat insulation pipe that has the non-metal electric heating fiber heating, the anti-corrosion heat insulation pipe that has the non-metal electric heating fiber heating that particularly a kind of transfer oil is used.
Background technique
At present, in order to keep the temperature of pipeline inner fluid, be incubated in the periphery of pipeline, but the temperature fluctuation of insulation back pipeline inner fluid is big, when the pipeline inner fluid is oil, its temperature can not be lower than 30 ℃, otherwise, will the wax phenomenon appear analysing, therefore, need the loop of heating in the periphery of pipeline, with the temperature stabilization in the holding tube, in addition, in the Development and Production of oil gas field, crude oil and water flow to well head from the shaft bottom, and enter various devices such as pipeline and oil storage tank and all can be corroded, fouling, therefore the influence of wax deposition, is necessary to take effective protective measures, prevent that above-mentioned phenomenon from occurring, and can reduce the cost of production in oil field.
Summary of the invention
The purpose of this utility model provides a kind of anti-corrosion heat insulation pipe that has the non-metal electric heating fiber heating, anticorrosion, the good heat insulating of this pipe, and wax-separating out-preventing, easy to use.
For achieving the above object, the utility model by the following technical solutions:
A kind of anti-corrosion heat insulation pipe that has the non-metal electric heating fiber heating; it comprises: external protection coating; be positioned at and be aligned in sequence with below the external protection coating: protective layer; the non-metal electric heating fiber zone of heating; fibre electroheating two ends in this zone of heating are connected with feed cable; be the seamless steel pipe that its outer wall scribbles the heatproof anticorrosive paint in advance below the fibre electroheating zone of heating, scribble anticorrosive paint at the inwall of seamless steel pipe.
The non-metal electric heating fiber electrothermal layer can adopt: the electrothermal layer that is coated the braid parallel laid of the non-metal electric heating fiber electrically-heated-wire of temperature-resistant insulation layer and glass fibre by the periphery; Or the electrothermal layer that directly twines with the peripheral non-metal electric heating fiber electrically-heated-wire that coats temperature-resistant insulation layer.
The utility model has the advantages that: anticorrosion, the good heat insulating of this pipe, can reduce the crude oil wax on the tube wall, and reduce fluid flowage friction resistance.
