In plants, boilers have typically been the most trouble prone equipment, being the most likely origin of a problem that leads to a forced outage. Because of this, there are well defined techniques to assess the condition and manage the lifecycle of boiler equipment for optimum reliability and efficient operation.

Petromaster provides the highest quality boiler inspection, and condition assessment services by providing thorough inspections, detailed reports, prioritized repair recommendations, and comprehensive documentation. A well-planned condition assessment program is essential for the continued availability and reliability of your boiler and associated equipment, as well as the safety of plant personnel.

In general, condition assessment relies on three pieces of information:

1. 1. The current type and extent of damage in the component
   2. The rate of damage accumulation
   3. The extent of damage required to cause failure

RLA & Condition assessment of boiler components using non-destructive techniques provides the healthiness of the components at the present condition which ensures and prevents premature failures. The condition assessment also ensures its full utilization up to its useful life.

Most condition assessment inspections involve a combination of techniques, depending on the specific unit history and operating conditions. Petromaster offers a wide range of industry-standard nondestructive evaluation (NDE) techniques to offer a customized inspection program, including:

Petromaster has an experienced metallurgical team offering inspection and testing with modern tools, specialized NDT and inspection techniques. The remnant life assessment is performed by utilizing combination of field Inspection and Laboratory analysis for estimating precise remaining life.
