We can then tailor products and services to improve your operation, including partial tube repair, in-situ repair, Convective Tube Solution™, CMS Eros™ as well as other options.

Repair Services to Fit Your Needs

Our goal is to get you back up and running to maximum efficiency as quickly as possible, so that you are able to realize measurable improvements immediately. We also work hand-in-glove with your management team to develop strategies that reduce associated costs required to complete necessary repairs. 

Partial Tube Repair

In many cases, damage to air heater tubes is localized and limited to one section of the tube. This is especially true when erosion is the primary damage mechanism and failures are located close to the tubesheet plate. When local damage is identified, CMS frequently recommends partial tube repairs of the air heater.

In-situ Repair

Access to an air heater is frequently limited by overhead obstructions or the location of adjacent equipment, such as economizers or dust collectors. In many cases, these obstructions make it difficult, if not impossible, to install full length replacement materials, without taking an extended outage.
