Pipe clamp in adapter；
It is 19500N to measure residual stress on the pipe clamp, meets design requirement, the year that the pipe clamp can be used is limited to 40
Year, and the actual life can illustrate that the residual stress on pipe clamp meets design requirement, and during because of operation, pipe clamp swell increment
More than tube bank swell increment, such as residual stress is too low, has the trend of fluffing, influence connection tube bank is fixed and insulating assembly is fixed,
If loosened, displacement can be produced in thermal stress situation lower tube clip, causes insulating assembly temperature compensation to meet requirement, shadow
The life-span is rung, when pipe clamp pretightning force is near required value, pipe clamp residual stress is not above pipe clamp allowable stress intensity, pipe clamp
Contact stress with tube bank ensures projected life also no more than tube bank and the allowable stress intensity of pipe clamp.Conversely, exceeding
The value, can make tube bank or pipe clamp stress level transfinite, influence tube bank and pipe clamp life-span.
Above in association with preferred embodiment the present invention is described, but these embodiments are only examples
Property, only play illustrative effect.On this basis, a variety of replacements and improvement can be carried out to the present invention, these each fall within
In protection scope of the present invention.
