UIB45

Sealed Inverted Bucket Steam Trap

(for use with Pipeline Connectors)

Description

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.

Standards

This product fully complies with the requirements of the European

Pressure Equipment Directive 2014/68/EU.

Note: The body/cover weld joint complies with ASME section IX.

Certification

This product is available with certification to EN 10204 3.1.

Note: All certification/inspection requirements must be stated

at the time of order placement.
