FIELD: machine engineering.
SUBSTANCE: in a device for cylinder charging and sealing under pressure, a sealing of a process opening for cylinder gas charging is provided by welding a conical plug along the end face of a charging union under the pressure of the working medium. The device provides an installation of the conical plug at working medium pressure, welding of the plug in the pressed state and a sealing test both after installation of the plug and after the welding.
EFFECT: enhanced reliability of the object as a whole, and reduced device production cost.
