Non-asbestos materials for sealing gaskets in ship pipelines connections

Authors: B.A. Gorelik

Abstract

The present article provides a solution to the problem of using non-asbestos instead of asbestos materials for making gaskets sealing the connections of ship pipelines. A comparison of the properties of the materials used in the flanged connections of ship pipelines has been made. The possible variants of replacing asbestos materials with non-asbestos ones not impacting the ship systems reliability have been given. These non-asbestos gaskets allow for the improvement of the pipelines ecological compatibility as a whole. Their technical characteristics also exceed those of asbestos-containing ones, the sizes meet the standards and are concentric with the holes for the fixing bolts.

Keywords: ship pipeline systems, flanged connections, pipelines reliability, asbestos, non-asbestos sealing materials.
