Standard three-way offset

A three-way offset is a multicomponent assembly of the pipe-line system with three connector ends, which is designed for connecting side subsidiary pipes to the main pipe-line and flow distribution in pipe-lines. Herewith the operating environment changes its direction at the angle 90°.
