METHOD OF ASSEMBLING HIGH-PRESSURE VESSEL Russian patent published in 2007 - IPC F17C1/00 A62C13/00 

FIELD: manufacturing high-pressure vessels.

SUBSTANCE: method comprises screwing the valving members in the neck with an arbitrary tightening torque with the use of a lubricant that is applied on the threaded section of the valving member from the side of its face within the section between the first and fifth turn of the thread along the 1±0.5 of the turn length over its periphery. The lubricant is made of a one-component anaerobic glue in amount corresponding to the volume of the spiral space between the turns of the neck thread and answering turns of the threaded section of the valving device over the length no less than one turn of the thread. The assembled vessel is then allowed to stand for forming a polymeric composition in the spiral space for at least 20 min at a temperature of no less than 5°C. The threaded connection is sealed by means of a polymeric composition.

EFFECT: enhanced reliability.
