Abstract
The invention discloses a heat traced petroleum pipeline which comprises an inner steel pipe, wherein a semicircular arc-shaped steel plate is arranged outside the inner steel pipe; horizontal steel plates are respectively arranged at central positions of two sides of the inner steel pipe; one end of each horizontal steel plate is connected with the inner steel pipe, and the other end of each horizontal steel plate is connected with the arc-shaped steel plate; the arc-shaped steel plate and the inner steel pipe sleeve with an outer steel pipe; gaps formed among the arc-shaped steel plate, the inner steel pipe and the outer steel pipe are filled with rock wool insulating materials. A semicircular gap is formed in the bottom outside the inner steel pipe conveying petroleum, hot water is added into the gap so as to heat the petroleum, the temperature of the petroleum is increased, the viscosity of the petroleum is reduced, the fluidity of the petroleum is increased, and the petroleum in the pipeline is heated from the lower side. Due to heating non-uniformity and different petroleum temperature, the petroleum is in turbulence, the pipe blockage possibility is reduced, and the petroleum pipeline is applicable to petroleum pipeline transportation in cold areas.
Description
Technical field
The present invention relates to petroleum pipeline technical field, especially a kind of heat tracing petroleum pipeline.
Background technology
Oil is a kind of pitchy being made up of various hydro carbons or dirty-green viscous liquid state or semi-solid combustible, especially
It is when temperature is relatively low, and the stickiness of oil increases, and mobility weakens, and easily blocks in course of conveying.In order to keep away
Exempt to occur petroleum pipeline clogging in autumn and winter microthermal climate, the best way is the temperature improving oil in pipe, reduces stone
Oily stickiness, increases the mobility of oil.
Content of the invention
The invention aims to solving the above problems, there is provided a kind of heat tracing petroleum pipeline.
The purpose of the present invention to implement by the following technical programs：
A kind of heat tracing petroleum pipeline, including in steel pipe, described interior steel pipe is externally provided with a semicircular curved plate, interior steel pipe both sides
Center is respectively provided with one piece of horizontal steel plate, one end of horizontal steel plate and interior fastener for connection, and the other end is connected with curved plate, institute
State curved plate and piece outer steel pipe of interior steel pipe socket, the space filling insulation rock being formed in curved plate, interior steel pipe and outer steel pipe
Cotton material.
Further, described interior steel pipe and outer steel pipe are arranged concentrically.
Beneficial effects of the present invention are：
The heat tracing petroleum pipeline that the present invention provides, forms semicircular space in the interior steel pipe exterior bottom of transfer oil, in sky
In gap, logical hot water is heated to oil, improves the temperature of oil, reduces oil viscosity, increases oil flow, in pipeline
Oil heats from bottom, uneven due to be heated, and oil temperature is different, makes oil be in turbulent flow, reduces line clogging
May be it is adaptable to the petroleum pipeline of cold zone transports.
Brief description
Fig. 1 is the structure chart of heat tracing petroleum pipeline of the present invention.
In figure：Steel pipe in 1-；2- heat preservation rock layer；3- horizontal steel plate；4- curved plate；The outer steel pipe of 5-.
Specific embodiment
As shown in figure 1, heat tracing petroleum pipeline described in the embodiment of the present invention, including in steel pipe 1, described interior steel pipe 1 is externally provided with
One semicircular curved plate 4, interior steel pipe 1 both sides center is respectively provided with one piece of horizontal steel plate 3, one end of horizontal steel plate 3 with
Interior steel pipe 1 connects, and the other end is connected with curved plate 4, described curved plate 4 and 1 set of outer steel pipe 5 of interior steel pipe, interior steel pipe 1
It is arranged concentrically with outer steel pipe 5, the space filling heat preservation rock layer 2 being formed in curved plate 4, interior steel pipe 1 and outer steel pipe 5.Work as stone
When oil needs heating, lead to hot water in the space that interior steel pipe 1, curved plate 4 and horizontal steel plate 3 surround, be petroleum.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to aforementioned reality
Apply example the present invention has been described in detail, for a person skilled in the art, it still can be to aforementioned each enforcement
Technical scheme described in example is modified, or carries out equivalent to wherein some technical characteristics.All essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
