Description
Technical field:
The utility model relates to petroleum pipeline interface unit technical field more particularly to a kind of pipe jointers.
Background technique:
Currently, the connection of conventional pipeline mainly passes through flange, gasket, bolt, nut combination in fact in petrochemical industry production
Existing.Since flange sealing surface is perpendicular to pipe centerline, connects bolt and be parallel to pipe centerline, this certainly will just bring following
Two influences: when working first, pipeline internal pressure will make sealing surface along duct orientation relaxation, to reduce junction leakproofness
Can, therefore, bolt load under pretension condition when certainly will increase installation, so that it is curved accordingly also to increase the flange that ring flange can bear
Square, so the structure size of flange also just seems coarse；Further, since connection bolt is parallel to duct orientation, therefore running
Generated pipe-line system additional load will directly be undertaken by flange bolt first under state, and it is pre- to also result in flanged joint
The decline of tight effect, and influence the sealing performance of connection.
The information disclosed in the background technology section is intended only to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition is already known to those of ordinary skill in the art existing
Technology.
