Spend a1For 10~20mm, inside inner tube is compared with outer tube extension width a4For 10~15mm.
In a kind of above-mentioned solid-state production tritium cladding modular shielding slab high-temperature pipe seal nipple, the lateral extension
Divide width a2For 100~200mm, inner and outer pipes coupling part width a3For 20~25mm
In a kind of above-mentioned solid-state production tritium cladding modular shielding slab high-temperature pipe seal nipple, the inner tube or outer
The thickness of pipe wall of pipe is 5~10mm.
The remarkable result of the present invention is：In the pipeline passed through inside solid-state production tritium covering shielding slab, section of tubing is used
In cooling agent and the conduction for putting forward tritium gas, pipeline wall surface temperature is more much higher than flange, and such knot will be used at flange seal
Structure thermal stress caused by alleviate high-temperature gradient.
The structure uses double-skin duct, and inner tube is connected with high-temperature gas, is vacuum environment between inner and outer pipes, with internal vacuum chamber
It is connected, inner and outer pipes are connected on the outside of flange, synthesize single tube, with the cooling agent of external secondary system and putting forward tritium gas pipeline phase
Even, inner tube is attached with outer tube on the outside of flange, greatly reduces temperature gradient；
There is certain thickness boss on the outside of the structure, for directly carrying out butt welding with the circular through hole on flange wall surface；
The structure inner and outer pipes contact position using certain arc angling excessively, concentrate to avoid thermal stress.
The present apparatus reduces temperature gradient, alleviates stress raisers, and heat stress value is dropped to French Nuclear Power correlation mark
It is accurate hereinafter, and structure it is relatively easy.
