Abstract

The short description of process of manufacturing of tape sealant is provided in article. Physicomechanical properties of tape sealant are defined, have been defined, dependence of way of forming of joint of tape hermetic has been investigated at assembly of pressurized compartments. Relative deformation at compression of hermetic tape, residual relative deformation after compression is established. Degree of fit of the tape sealant to interfaced surfaces in different combinations of materials: «aluminum–PCM» with two-row and single-row bolted, «aluminum–organic glass» with two-row bolted.
