Solderless pipe joint e.g. for pipes carrying gas in semiconductor manufacture production line

摘要

The joint consists of a housing (14) which holds the ends of the two pipes (12A, 12B) being connected, and a threaded locking member (13) which is screwed into the housing to compress the two parts (17A, 17B) of an elastic seal surrounding the pipe ends. The seal is compressed between two sets of rings (15A, 15B; 16A, 16B) with thrust bearings (22A, 22B).
