Aquatherm Advantages

  • The polypropylene pipe was able to withstand the high temperatures of the condensate
  • Since PP-R is chemically inert, no protective chemicals are necessary for the pipe – unlike steel
  • Returning the condensate to the facility at a higher temperature saves energy

The Challenge

A 650-foot steel condensate line had corroded completely and required a replacement that could withstand high temperatures without breaking down.


The Solution

A directional bore process was used to install Blue Pipe at the facility without disrupting the road or grounds.


SSM Cardinal Glennon Children’s Medical Center is a not-forprofit, 190-bed inpatient and outpatient pediatric medical center in St. Louis. The hospital is home to the Bob Costas Cancer Center, Dana Brown Neonatal Intensive Care Unit, St. Louis Fetal Care Institute, Dorothy and Larry Dallas Heart Center, St. Louis Cord Blood Bank, and the Missouri Poison Center.

Serving children locally and internationally, the hospital focuses on caring, commitment and excellence, and that focus carries over to its physical plant and facilities. The facility staff strives to ensure all systems are performing at their optimum levels.

In late 2010, the staff learned that the buried 650-foot, Schedule 40 carbon steel condensate line running from the Pediatric Research Institute to the main boiler room had completely corroded. The 2-inch low-pressure line had been installed approximately 20 years ago, and due to corrosion, had stopped returning condensate for re-use in the power plant.
