One option is to conduct a hydrostatic pressure test to levels well above the operating stress or pressure level to establish whether a defect condition could impair the immediate integrity of a pipeline (allowing defects much smaller than would be critical at operating conditions to remain after a test).
Consequently, the uniformity of the operating stress experienced in the melt mixing section was higher with BMS than FKD and the fraction subjected to insufficient kneading action is thought to be lower.

The new K-Series loaders also incorporate an electronic snubbing feature at end-stroke and kick-out positions to reduce operating stress.
research carried out regardless of the level of operating stress amplitude, while it is known (Collins 1993) that different levels of operating stress amplitude correspond to the different laws of damage accumulation.
We are using the term "design life" to mean the minimum desired time that the assembly will last at its maximum operating stress and average annual operating temperature based on just the internal pressure.
The methodology we used for forecasting long-term aging shows that performance is a function of the water quality, water temperature and operating stress, all of which will vary by utility," stated Ken Oliphant, PhD, P.
