Description

The UIB30 and UIB30H are sealed inverted bucket steam traps

for either horizontal or vertical installation (with the cover hanging

downwards). The UIB30H is designed for higher capacities. When

installed with a suitable pipeline connector (available separately

from Spirax Sarco) the UIB 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.

The UIB can be fitted to a variety of pipeline connectors including:

PC10HP Straight connector

PC20

+ 'Y' type strainer

PC3_

+ 1 piston isolation valve

PC4_

+ 2 piston isolation valves
