In the environment of surrounding.
Therefore, Chinese patent 200820117969.7 discloses a kind of interior heating polyurethane foam jacket pipe, solve
Certainly lack the problem that a kind of tubing can be directly realized by heat tracing during conveying crude oil in prior art.It is characterized in that：
It is sequentially distributed anticorrosive coat, heat conducting film from the inside to the outside between the outer wall of described steel pipe and the inwall of polyethylene Huang jacket exodermis
Layer and polyurethane foam insulation layer, being wherein located at has carbon fiber electrothermal line between heat conduction film layer and polyurethane foam insulation layer, this
Its two ends of carbon fiber electrothermal line are passed through outside insulation joint terminal fairlead.This kind of interior heating polyurethane foam jacket pipe is capable of
Direct heat tracing during conveying crude oil, has that heat tracing effect is good, energy consumption is low, can simplify petroleum transferring station technological process, optimize collection
The feature of defeated pipeline.But, this technical scheme is using carbon fiber electrothermal line as the generator of heat energy, equal by heat energy by heat conducting film
Even be transferred to oil transportation steel pipe, the heat production of carbon fiber electrothermal line local, operating efficiency is low, and heating is uneven, in cold extreme sky
Under gas, utilidor is susceptible to pipe after heating up suddenly in local and splits.
