Superheater & reheater attemperator pipe spools

Common problems include thermal fatigue and cracking caused by water overspray and damaged spray probes. HRST can provide an upgraded pipe spool to improve life of the attemperator pipe section.

Pinned and guided internal liner system that does not weld to the pipe.
Protects downstream and upstream spray probe
New spool and spray probe nozzle material restores the pressure parts to full fatigue life

Economizer Return Bend Failure Mitigation

Are your experiencing repeated failures in the upper return bends? Return bends looped over a support are a nightmare to repair. HRST can design a modified support system to prevent such failures.

Pipe liner for Reheater Desuperheater

“We had a short outage and needed a pipe liner for a reheater project. The attemporator was broken off and we needed expert recommendations for repairing the nozzle. HRST, Inc. was just great. They really helped us out a lot. They sent us a new liner right away. We had several questions about fitting the liner and we needed several on-site modifications. What impressed me was how helpful HRST, Inc. was throughout the entire process. All of our questions were answered immediately and we got all the help we needed to make this project work for us. I would definitely recommend your company to any facility with a similar need. We certainly plan on working with your firm in the near future.”
