FIELD: machine building.
SUBSTANCE: invention relates to high pressure vessels for placement of various fluid media under pressure. A boss for a high pressure vessel has a flange. The specified flange has an outer side and an inner side. Besides, the boss comprises an inner mounting slot and multiple channels. The specified mounting slot is placed on the specified internal side and has an inner side wall. Multiple channels are placed in the specified inner side wall. Besides, channels do not communicate with the outer side. Also versions are described for execution of a high-pressure vessel, as well as the method for execution of a high-pressure vessel.
EFFECT: group of inventions is aimed at prevention of possibility of gaseous medium leakage at inner side of a flange to outer side of a flange.
