Reformer Tube Inspection with FFS

At TCR we have developed ARTiS – Automated Reformer Tubes Inspection System, a cutting-edge solution for the comprehensive assessment of reformer tubes. Having completed over 100 projects for clients in India and internationally, TCR is the leader in reformer tube integrity assessments. Our multidisciplinary approach incorporates Fitness for Service (FFS) analysis as per API579/ASME FFS1 and features a unique ability to determine "when to retire tubes." Over the years, TCR has developed an extensive database of reformer tube failure mechanisms, allowing our research wing to identify early warnings of tube failures with unparalleled accuracy.

 

TCR’s deep understanding of the operational and metallurgical interactions of reformer tubes, combined with our innovative ARTiS technology, enables us to deliver superior insights into the condition of your tubes. With automated crawlers that accommodate tube outer diameters from 105 mm to 190 mm, ARTiS provides precise data for Level III FFS assessments, ensuring the accurate prediction of remaining tube life.

 

Key Features of TCR's Reformer Inspection using ARTiS:

Multi-technique approach for detailed condition assessment of reformer tubes

Level III FFS Assessment as per API579/ASME FFS1 for remaining life calculations

Proprietary standard samples with known damage scenarios, offering superior accuracy

Ultrasonic attenuation measurement for fissure detection via automated crawler

In-situ metallography for microstructural analysis to assess microstructural degradation

Visual Inspection for bulging, baldness, sagging, and bowing by an expert

Automated Outer Diameter Measurement with electronic devices on ARTiS at intervals of 0.1M using infrared light sensors

Automated Bowing Measurement with on-board electronic devices

Hardness Testing at metallography locations

Manual Ultrasonic Wall Thickness Measurement at platform (bottom) level

Magnetic Permeability Measurement at platform level

 

TCR provides a detailed Level III FFS Assessment in accordance with API579/ASME FFS1 Inspection results summarizing accumulated creep damage including calculation of effective tube metal temperature and projected creep damage up to the next shutdown. Retirement date prediction based on accumulated creep damage (0.8 life fraction) and Remaining life assessment for each tube.
