The effect of downstream perforated blanket on the safety against piping in heading-up structures
Agamy, Ahmed; Mona A. Hagras;
Abstract
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 different series of heading up on the safety against piping.
It was found that piping index (Pe) is governed by 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.
