Abstract
The utility model discloses a kind of bracing means of high temperature and high pressure steam pipeline weak location, including pipeline (1), and be closely wound by circumferential direction in several copper coils (2) of the pipeline (1) weak location, for playing the role of restrained reinforcement to pipeline (1).The utility model is used to delay the failure of pipeline weak part, gains time to subsequent processing.
Description
Technical field
The utility model belongs to thermal power generating technology field, and in particular to a kind of high temperature and high pressure steam pipeline weak location
Bracing means.
Background technique
Meeting during its manufacture, installation, welding, heat treatment or military service of thermal power plant's high temperature and high pressure steam tube metal material
Local weak position is generated, such as there are the weld seam softened zone of creep impairment and welding defects etc..The failure major part feelings of pipeline
It is since local weak position under condition.(defect is carried out at digging if do not handled in time the weak part of pipeline
Reason or replacement problem pipeline section), it will the safe operation generation of pipeline seriously threatens.But specific to actual conditions, possibility is temporarily
Be unsatisfactory for treatment conditions, for example suitable spare unit pipeline can not be purchased in time etc., to avoid occurring accident, ginseng can only often drop
Number operation or hesitation, lose massive profits.
Utility model content
The utility model aim is to provide a kind of bracing means of high temperature and high pressure steam pipeline weak location, for delaying
The failure of pipeline weak part gains time to subsequent processing.
What the utility model adopts the following technical solution to realize:
A kind of bracing means of high temperature and high pressure steam pipeline weak location, including pipeline, and be closely wound by circumferential direction
In several copper coils of the pipeline weak location, for playing the role of restrained reinforcement to pipeline.
The utility model, which further improves, to be, several copper coils are closely arranged, and two neighboring copper coil is tightly attached to one
It rises, and circumferential direction connects two neighboring copper coil using spot welding at 90 ° one.
The utility model, which further improves, to be, the head and the tail of each copper coil are linked together by melting welding mode.
The utility model, which further improves, to be, the nominal outside diameter of the pipeline is in 159mm or more.
The utility model, which further improves, to be, the length of copper coil are as follows: (duct length × pipeline perimeter)/copper wire is straight
Diameter.
The utility model, which further improves, to be, the diameter of copper coil are as follows: diameter=(pipeline internal pressure stress × duct wall
It is thick) allowable stress of/copper wire at a temperature of pipeline steam.
The utility model has following beneficial technical effect:
A kind of bracing means of high temperature and high pressure steam pipeline weak location provided by the utility model, passes through several copper coils
It is closely wound in the circumferential direction of pipeline, for delaying the failure of pipeline weak part, gains time to subsequent processing.
In addition, being only capable of as a kind of device for temporarily delaying pipeline failure, it is impossible to be used in long service is using the device
Period should purchase spare unit pipeline section as early as possible or connection arranges defect repair, while reinforce the supervision to copper wire.The supervision of copper wire is main
It include that nothing loosens, whether there is or not cracking, copper wire hardness etc. for weld seam solder joint.
Detailed description of the invention
Fig. 1 is a kind of bracing means structural schematic diagram of high temperature and high pressure steam pipeline weak location of the utility model.
Specific embodiment
The utility model is made further instructions below in conjunction with attached drawing.
As shown in Figure 1, a kind of bracing means of high temperature and high pressure steam pipeline weak location provided by the utility model, including
Pipeline 1, and be closely wound by circumferential direction in several copper coils 2 of 1 weak location of the pipeline, for playing constraint to pipeline 1
The effect of reinforcing.
Closely arrangement, two neighboring copper coil 2 are close together several copper coils 2, and circumferential direction is adopted at 90 ° one
Two neighboring copper coil 2 is connected with spot welding, the head and the tail of each copper coil 2 are linked together by melting welding mode.
In addition, the nominal outside diameter of the pipeline 1 is in 159mm or more.The length of copper coil 2 are as follows: (duct length × pipeline week
It is long)/copper wire diameter.The diameter of copper coil 2 are as follows: diameter=(pipeline internal pressure stress × pipeline wall thickness)/copper wire is in pipeline steam temperature
Allowable stress under degree.
