Description
Technical field
The utility model is related to a kind of stainless steel pipes, more specifically, it relates to a kind of freeze proof steel pipe.
Background technology
Steel pipe is a large amount of conveyings for being used as fluid, the manufacture of machine components and engineering structure, with higher intensity
Lighter weight is a kind of very ideal tubing.
Steel pipe can be divided into two major classes by production method：Seamless steel pipe and seamed steel pipe, seamed steel pipe are referred to as steel pipes with straight.
Seamless steel pipe can be divided by production method：Hot seamless tube, drawn tube, precision tube, hot-expanding pipe, cold spinning pipe and extruded tube
Deng.Seamless steel pipe is made of Fine Steel Casting iron or steel alloy, there is hot rolling, cold rolling（It pulls out）Point.Seamless steel pipe can be used for various rows
The liquid air-pressure duct of industry and gas pipeline etc..Welded pipe line can be used for aqueduct, gas piping, caliduct, electric appliance pipe
Road etc..
When steel pipe is used as pipeline described in fluid, low temperature environment can be sometimes faced, in low temperature environment, the fluid in steel pipe
Due to heat Quick diffusing, temperature reduces, and is susceptible to the case where freezing, to produce and life brings loss.
The antifreezing measures that existing steel pipe is taken are usually but this antifreezing measures in tube body outer wrapping thermal insulation material
Effect is not satisfactory.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of freeze proof steel pipe, have
The freezing tolerance of color can cope with various severe low temperature environments.
To achieve the above object, the utility model provides following technical solution：
A kind of freeze proof steel pipe, it is characterized in that：Including inner tube and outer tube, it is provided between the inner tube and outer tube
PTC heating plates, the PTC heating plates are uniformly distributed along the circumferential direction of inner tube, and there are gap, institutes between adjacent PTC heating plates
The two sides of PTC heating plates is stated as, with the arc surface of curvature, the two sides of the PTC heating plates is fitted with inner tube and outer tube
Arc-shaped electrode, the electrode are connected with conducting wire, and the conducting wire is used to connect external power supply, PTC heating plates two sides
Electrode and the contact area of inner tube and outer tube are provided with felt pad.
Preferably：It is provided between the electrode of lateral surface and the inner wall of outer tube of the PTC heating plates heat-insulated
Layer.
Preferably：It is marked with thermal conductive insulation glue in the gap.
Preferably：Insulating layer is set on the outer wall of the outer tube.
Preferably：The thermal insulation layer is rock wool layer.
Preferably：The insulating layer is aluminium foil layer.
Preferably：The felt pad is plastic mattress.
Compared with prior art, the utility model has the advantages that：PTC heating plates built in the freeze proof steel pipe, need at work
External power supply is connected, while it is working, PTC heating plates, which are powered, generates heat, is heated to the fluid in steel pipe, makes the steady of fluid
It is fixed to increase, prevent fluid freeze.In addition, since PTC heating plates are heated at constant temperature devices, being stably maintained in steel pipe can guarantee
Within the scope of one stationary temperature, to enable the steel pipe to cope with severe low temperature environment.
