The UIB45 is a sealed inverted bucket steam trap for either horizontal or vertical installation (with the cover hanging downwards). When
installed with a suitable pipeline connector (available separately from Spirax Sarco) the UIB45 can easily and simply be removed without
breaking into the pipeline, thus speeding up trap replacement with minimal system downtime. Pipeline connectors are available with
screwed, socket weld and flanged end connections.
