FACILITY FOR SUPPLY OF CORROSIVE AND/OR ABRASIVE MEDIUM

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention refers to protection of materials from corrosion, sedimentations and wear. The facility consists of external gas-proof wall and internal metal gas-proof wall arranged with a gap between them. The internal metal gas-proof wall is made out of porous material wherein dimension of pores diminishes to surface in thickness of wall. Surface of this wall contacts flowing medium. Also permeability decreases along length of the wall from the inlet of the facility to its outlet, thus compensating drop of pressure of corrosive and/or abrasive medium. ^ EFFECT: protection of internal surface of facility walls from corrosive and/or abrasive medium. ^ 6 cl, 7 ex
