METHOD AND DEVICE FOR CONNECTING A SUBMERSIBLE ELEMENT TO AN ENCLOSURE UNDER VERY HIGH PRESSURE

摘要

In the correction of a cylinderical or tubular element to a tubular sleeve (M) for engaging a submersible heating element in a pressurd water nuclear power station primary circuit, a sealing joint (130) of T-shaped cross-section is between flanges on the heating element. A male screwing element bears against thrust half-rings (140) and a female screwing element bears against the flange on the heating element. The flanges are shaped to create a chamber forming a basin in which the projecting portion (125) of the joint is mounted. The male element has a latching edge at one end of the connection and the heater flange has a thrust shoulder.
