Methods for sealing shell structures made of polymer composites

Abstract

Items are classified according to the requirements on their sealing, and general demands on the degree of sealing of structures used in various branches of industry are described. The coefficients of media diffusion obeying the Fick and Henry laws through many polymeric materials are given. Factors affecting the diffusion coefficients are considered. The technology of contour sealing along the outer surface of technological shells and internal surface of final items is described. Advantages and disadvantages of each sealing method considered are shown. The technological specific features of local sealing of dismountable joints are described. The technology of sealing of flanged and nipple joints is discussed.
