ECONOMIZER EXPANSION JOINT
Turn-Key Service – Fabrication, Scaffolding and Installation
Executive Summary
An expansion joint in an Power Plant Economizer inlet duct rated at
750 degree F was in need of replacement. This duct was located up
over 70 ft up in the air and safe access was required. The plan was
to remove and replace the fabric belt and damaged flow liner
shield. Helfrich Brothers was able to supply all 3 services under one
turnkey contract.
Field Service – Remove & Installation
Field Service group removed existing fabric joint, and replaced it with a new high temperature insulation pillow and
the fabric expansion joints fabricated in our shop. A partial
metal flow liner was replaced in worn out area.
The project occurred during a normal spring outage in
2021.
“Having Helfrich Brothers coordinate and manage the entire project made this a success.”
