The effect of downstream perforated blanket on the safety against piping in heading-up structures

This paper presents the results of an experimental study on the effect of using a perforated blanket downstream the aprons of heading-up structures with different scenarios of blanket length with different Perforation ratio and different holes diameter, presence of different cutoffs and Brass Flare T-Union different series of heading up on the safety against piping.It was found that piping index (Pe) is governed by Fill-In Fibers perforation ration (PR), relative hole diameter (D/Lb), ratio of length of the blanket to length of the apron (Lb/La), head difference between upstream and downstream structure and the depth of downstream cutoff.
