METHOD TO PREVENT CORROSION OF PIPELINE, COMPOSITE STRUCTURE FOR EXTERNAL SURFACE OF PIPELINE AND SET TO ARRANGE INSULATING PROTECTIVE COVERING COMPOSITE STRUCTURE

摘要

FIELD: machine building.;SUBSTANCE: method includes stages, where porous insulation is formed in the form of extended arched elements, a layer of a sodium silicate solution is applied onto the specified insulation and at least partially into its pores. The layer of the sodium silicate solution is hardened to the threshold condition. The external surface is adhered to the layer of the sodium silicate solution upon completion of the hardening stage. Insulation is installed onto the outer surface of the pipeline, and open edges or seams are sealed between installed items. The structure arranged according to this method may have a separating film and a contact glue.;EFFECT: possibility to prevent corrosion.;21 cl, 8 dwg, 1 tbl
