Intertek has developed an innovative Total Quality Assurance system using TubeAlert SM and TubeTech SM to assess the remaining useful life of boiler tubes so that critical areas can be identified and early tube failure avoided. Meanwhile TubeMod SM optimises the lifespan and usage of boiler tubes.

2017-5-27 · Remaining Life Analysis Of A Steam Boiler Tube Okpala, Alexander N. and Adigio E.M. Department of Mechanical Engineering,Niger Delta University,Wilberforce Island, Bayelsa State, Nigeria ABSTRACT:- Remaining life analysis of a failed in service steam boiler was conducted using Neubauer’s classification of creep damage.

Cited by: 3The remaining life of each tube/tube assembly is predicted using a computer code known as TUBELIFE, thus achieving a further level of focus on the tubes/assemblies in the highest risk'' category.

Recommend Strategies to Prevent Boiler Tube Failures; Predict Boiler Tubing Remaining Useful Life; Boiler tube failures are the leading cause of steam plant reliability issues. A tube failure may cause a forced outage, usually at the most inopportune time. The outage results in lost production and lost revenue. Reducing boiler tube failures

Statistical Analysis Two level factorial design was adopted to find main and interacting affects of process variables on the remnant life and the creep damage of
