Hi,
In normal temperature, the spring is compressed to △L2; But in cryogenic temperature, due to dimensions shrinkage (the length of spring shrink, and both ends of the dimensions of components shrink), the pre-compression is reduced (up to △L1),at this time, the reducing range of output force...
In API 6A-20th, the appendix D indicates the pre-tightening force of flange bolting is the half of material minimum specified yield strength.
1. For the specified value in appendix D,does it mean the pre-tightening force of flange bolting in API 6A must be the half of the yield strength of the...
