TO A QUESTION OF RESEARCH OF HARDNESS AND TIGHTNESS OF A SHUT-OFF HIGH- PRESSURE ACCESSORY OF TANKS OF FIRE ENGINEERING

Abstract

The question of research of stress in a contact zone

of parts of a shut-off high-pressure accessory of tanks of engineering of lire extinction is considered. The approach bases on ratios of a plane problem of the elastic

theory. The procedure is illustrated with a numerical example.
