Quick Opening Closures-A New Stage in Petrochemical Industry

At new construction and reconstruction of petrochemical production facilities for replacement of bolted equipment covers and hatches are widely used quick opening closures of different design. In this paper are analyzed quick opening closures of covers and hatches as well as pipelines, chambers and apparatuses dead end sections. Their advantages and shortcomings are presented. It is shown that high reliability, fabricability and ease of use requirements are met by new generation quick opening closures–ZKSsh/Zatvor Kontsevoi Sektorny Sheryk=Sector End Closure by Sherik. The closure design makes it possible to fabricate and deliver it both as an equipment component and in the form of a separate finished product to be installed at various vertically or horizontally oriented branch pipes, including in replacement of the existing fixtures in all possible diameter and pressure ranges.
