Description
Technical field
The present invention relates to tubing manufacturing technology field more particularly to a kind of Ni-based conjunctions of heavy caliber ultra-thin-wall of nuclear power control rod
Golden tubing.
Background technique
Rate in order to control chain reaction need to be made into absorption with the material for absorbing neutron in a scheduled level
Stick, referred to as control rod and safety rod.Control rod is used to compensate fuel consumption and adjusts reaction rate, and safety rod is used to quickly stop
Only chain reaction, absorbent material are usually boron, boron carbide, cadmium, silver-colored indium cadmium etc..Heavy caliber on nuclear power control rod is Ni-based
Alloy pipe in process of production, often due to make to generate defect in tubing wall the reason of thick tube wall, especially generation shrinkage cavity,
It is substantially reduced the mechanical property of tubing, has seriously affected the quality of product, service life is shortened.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of nuclear power control rod heavy caliber ultra-thin-wall nickel-base alloy tubing,
To solve deficiency in the prior art.
In order to achieve the above object, the purpose of the present invention is be achieved through the following technical solutions:
A kind of nuclear power control rod heavy caliber ultra-thin-wall nickel-base alloy tubing, including pipe shaft and connector, the connector are provided
It is equipped with flange close to the periphery of the end of the pipe shaft, in one section of insertion pipe shaft of the connector outside the flange, the pipe
Body successively includes outer layer ultra-thin-wall nickel-based alloy pipe, enhancement layer and internal layer ultra-thin-wall nickel-based alloy pipe from outside to inside.
Above-mentioned nuclear power control rod heavy caliber ultra-thin-wall nickel-base alloy tubing, wherein in the Ni-based conjunction of outer layer ultra-thin-wall
The outside of golden pipe is equipped with several spaced glass fabric reinforcing rib rings.
Above-mentioned nuclear power control rod heavy caliber ultra-thin-wall nickel-base alloy tubing, wherein the outer layer ultra-thin-wall nickel-base alloy
Auxiliary enhancement layer is further respectively had between pipe and the enhancement layer, between the enhancement layer and internal layer ultra-thin-wall nickel-based alloy pipe.
Above-mentioned nuclear power control rod heavy caliber ultra-thin-wall nickel-base alloy tubing, wherein the outer layer ultra-thin-wall nickel-base alloy
Pipe and the internal layer ultra-thin-wall nickel-based alloy pipe thickness no more than the pipe shaft outer diameter 1/50.
Above-mentioned nuclear power control rod heavy caliber ultra-thin-wall nickel-base alloy tubing, wherein the enhancement layer and the auxiliary increase
Strong layer is compound PE resin layer.
Compared with the prior art, the beneficial effects of the present invention are:
This tubing, which is avoided that in production inside tubing, generates shrinkage cavity, is avoided that surface damage during the installation process, improves
Product quality extends product service life.
Detailed description of the invention
The attached drawing for constituting a part of the invention is used to provide further understanding of the present invention, schematic reality of the invention
It applies example and its explanation is used to explain the present invention, do not constitute improper limitations of the present invention.In the accompanying drawings:
Fig. 1 shows the structural schematic diagram of nuclear power control rod heavy caliber ultra-thin-wall nickel-base alloy tubing of the present invention；
Fig. 2 shows the nuclear power control rod of the present invention structural representations of the pipe shaft of heavy caliber ultra-thin-wall nickel-base alloy tubing
