Patent
A radial holding device for the bundle and brace plates envelope in a vapor generator, by the means of enclosed screw stops
Description
With the aim to protect the envelopes and bundles against seisms or other constraints, without causing interference with the water flow or being too complicated to install, as with previous systems, a holding system is proposed which uses screw stops fixed to the envelope and to the brace; the screw, enclosed in one of the two parts, ensures, during the assembly, the displacement of the second part for good contact with the brace plate. 6 fig
