Abstract
The continuous running temperature experimental rig of prefabricated direct-buried thermal insulation pipe, by heat-conducting oil furnace, flowline, go out oil bumper, return oil buffer and oil return pipe and constitute, heat-conducting oil furnace is connected by flowline with going out oil bumper, go out oil bumper and some outlets are set, return oil buffer corresponds to out oil bumper and sets some imports, go out and some prefabricated direct-buried thermal insulation pipes are connected between the outlet of oil bumper and the import of return oil buffer, return oil buffer is connected by oil return pipe with heat-conducting oil furnace.The utility model device realizes the continuous running temperature detection of prefabricated direct-buried thermal insulation pipe, and the quality for detection direct-buried thermal insulation pipe in industry provides an important detection foundation, had the advantages that simple in construction and easy to detect.
Description
Technical field
The utility model is related to direct-buried pipe technical field of quality detection, and in particular to a kind of prefabricated direct-buried thermal insulation pipe is continuously transported
Trip temperature experimental rig.
Background technology
Direct-buried thermal insulation pipe is widely used in the transmission pipeline network of liquid, gas, chemical pipeline heat insulating work oil, chemical industry, concentration
Heat supply heat supply network, ventilating duct of central air conditioner, municipal works etc..High temperature prefabricated direct-buried thermal insulation pipe is a kind of good heat insulating, plus peace
Complete reliable, the direct-burried of low engineering cost is heat preservation pipe prefabricated.Effectively solve 130 DEG C of -600 DEG C of high temperature in the central heating of cities and towns
The insulation of defeated heat prefabricated direct-buried thermal insulation pipe, the waterproof problem for sliding lubrication and exposed pipe end.The thermal life of direct-buried thermal insulation pipe is
The crucial quality index of one, direct-buried thermal insulation pipe needs to carry out temperature tolerance experiment and calculates its institute's energy in the case where ensureing 30 year life-span
The maximum continuous operating temperature of tolerance（That is ccot）, the temperature should be higher than that pipeline actual motion temperature, current direct-buried pipe
Continuous running temperature does not have dedicated experiments device also.
Utility model content
The utility model is in view of the deficienciess of the prior art, there is provided a kind of continuous running temperature of prefabricated direct-buried thermal insulation pipe
Experimental rig.
The utility model solves the technical scheme that its technical problem used：
A kind of continuous running temperature experimental rig of prefabricated direct-buried thermal insulation pipe, by heat-conducting oil furnace, flowline, go out oil bumper,
Return oil buffer and oil return pipe composition, heat-conducting oil furnace are connected by flowline with going out oil bumper, are gone out oil bumper and are set some
Outlet, return oil buffer corresponds to out oil bumper and sets some imports, goes out the outlet of oil bumper and entering for return oil buffer
Some prefabricated direct-buried thermal insulation pipes are connected between mouthful, return oil buffer is connected by oil return pipe with heat-conducting oil furnace.
The continuous running temperature experimental rig of the utility model prefabricated direct-buried thermal insulation pipe is in use, first will be to be detected prefabricated straight
Bury insulating tube to be connected to out between the outlet of oil bumper and the import of return oil buffer, start heat-conducting oil furnace, pass through conduction oil
Stove is by conduction oil is by flowline and goes out oil bumper and delivers in prefabricated direct-buried thermal insulation pipe, and conduction oil passes through prefabricated direct-buried insulation
Pipe, return oil buffer and oil return pipe are returned again into heat-conducting oil furnace, so that completing prefabricated direct-buried thermal insulation pipe carries out thermal aging test,
And its tangential shear strength is determined under condition of different temperatures, when the tangential shear strength drops to the time used in 0.13MPa
I.e. the thermal life of tubing is worth, and no less than three temperature spots of degradation selection are carried out, based on tubing at three different temperature
The detection of tangential shear strength and Arrhenius equation relational expression, so as to calculate the continuous running temperature that tubing is resistant to
CCOT。
The utility model device realizes the continuous running temperature detection of prefabricated direct-buried thermal insulation pipe, is that detection direct-burried is protected in industry
The quality of warm pipe provides an important detection foundation, has the advantages that simple in construction and easy to detect.
Brief description of the drawings
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
1 heat-conducting oil furnace, 2 flowlines, 3 go out oil bumper, 4 prefabricated direct-buried thermal insulation pipes, 5 return oil buffers, 6 oil returns in figure
Pipe.
Embodiment
As shown in the figure：A kind of continuous running temperature experimental rig of prefabricated direct-buried thermal insulation pipe, by heat-conducting oil furnace 1, flowline 2,
Go out oil bumper 3, return oil buffer 5 and oil return pipe 6 to constitute, heat-conducting oil furnace 1 is connected by flowline 2 with going out oil bumper 3, is gone out
Oil bumper 3 sets some outlets, and return oil buffer 5 corresponds to out oil bumper 3 and sets some imports, goes out oil bumper 3
Some prefabricated direct-buried thermal insulation pipes 4 are connected between outlet and the import of return oil buffer 5, return oil buffer 5 is by oil return pipe 6 with leading
Hot oil furnace 1 is connected.
The continuous running temperature experimental rig of the utility model prefabricated direct-buried thermal insulation pipe is in use, first will be to be detected prefabricated straight
Bury insulating tube to be connected to out between the outlet of oil bumper and the import of return oil buffer, start heat-conducting oil furnace, pass through conduction oil
Stove is by conduction oil is by flowline and goes out oil bumper and delivers in prefabricated direct-buried thermal insulation pipe, and conduction oil passes through prefabricated direct-buried insulation
Pipe, return oil buffer and oil return pipe are returned again into heat-conducting oil furnace, so that completing prefabricated direct-buried thermal insulation pipe carries out thermal aging test,
And its tangential shear strength is determined under condition of different temperatures, when the tangential shear strength drops to the time used in 0.13MPa
I.e. the thermal life of tubing is worth, and no less than three temperature spots of degradation selection are carried out, based on tubing at three different temperature
The detection of tangential shear strength and Arrhenius equation relational expression, so as to calculate the continuous running temperature that tubing is resistant to
CCOT。
