While carrying out Stress analysis we generally take coefficient of static friction as 0.3 to determine forces at sliding surfaces for Steel to Steel.
If :
1. Plant is located near Coastal Area.(Atmospheric corrosion will increase its roughness factor.
2. Lines routed on Structural Piperack, during rainy season
the bottom of pipe might get eroded due to rain drops flashing on structural surface near bottom of pipe affecting again in roughness factor.
My question is, shouldn't this factor of 0.3 be increased.
If yes, then what should be that figure.
