Maximize Your Tubing Inspection

When constraints such as limited outage time or budgets disallow a more comprehensive assessment, even a limited boiler tubing inspection can provide valuable information regarding the overall condition of the boiler and its components. With proper planning and thorough surface preparations, an array of information can be gathered and serve to diagnose and predict imminent failures as well as provide estimates for the remaining useful life of the components. Boiler tube failure mechanisms that may occur individually or collectively include:

The presence of these failure mechanisms can be revealed through a targeted inspection of the tube bundle girth welds. The surface preparations for such an inspection can be as limited as a 4 inch band sandblasted clean to shiny metal on either side of the girth weld. Despite a relatively small area for inspection, the following examinations can be performed to expose adverse conditions:

When a row of tube butt welds is inaccessible, most of these examinations can be performed on more accessible portions of the tube bundle providing the same quality information. These measurements, when combined with tube specification data (material, pressure, temperature, etc.), allow for a comprehensive analysis of the condition of a boiler or component in a time and cost-effective manner.

Thielsch Engineering has over 30 years of experience performing condition assessments, engineering analyses, remaining life determinations, failure analyses, nondestructive examinations, and repair services for power generating and industrial plants on a national and international level. Our expert inspectors are qualified to meet the requirements of the American Society for Nondestructive Testing Practice SNT-TC-1A as well additional codes and standards. Thielsch Engineering has extensive laboratory capabilities and state-of-the-art inspection equipment and materials offering a full range of advanced engineering services.
