PIPE JOINING CONSTRUCTION.

摘要

A pipe joining construction which maintains airtightness for a long period of time, easily ensures the required dimensional accuracy, and surface finish accuracy, and can decrease cost. The pipe joining construction is characterized by a seal member S mounted at the outer periphery of a male end form (2) on a connector (1) or a pipe M and a collar (5) covering the outer periphery of the tip end of the male end form (2). The collar (5) has a tapered portion with a tapered outer periphery. The collar (5) is used as a holding member for the seal member S. Alternately, a ring member (11) is mounted between the seal members and a bead (26) on the male end form (2).
