Service Applications Across the TCR Continuum
A steel plant is simultaneously a producer and a heavy consumer of integrity services. On the production side, the plant certifies its own product, and TCR's role is independent verification: mechanical, chemical, and metallurgical testing of primary steels to ASTM, EN, JIS, and IS specifications.
On the asset side, the plant carries some of the harshest equipment duty in industry: blast furnace shells and stoves, basic oxygen furnace and electric arc furnace hoods, ladles and tundish structures, caster segments, reheating furnace tubes in creep service, rolling mill rolls and gearboxes, and direct reduced iron reformers running the same creep and carburisation mechanisms as fertiliser reformers. Shutdown windows are set by campaign life and relines; procurement risk sits in rolls, refractories, castings, and spares. TCR Engineering and TCR Advanced service all five stages of the five-stage Trusted Relationship Model (see Why TCR) for integrated, secondary, and direct reduction producers.
Stage One, Sourcing and Procurement: TCR qualifies rolls, castings, forgings, refractory anchor systems, and structural steel through mechanical, chemical, and metallurgical testing, runs vendor factory audits and original equipment manufacturer qualification for mill equipment, and verifies incoming ferroalloys, scrap-mix inputs, and consumables through the chemical analysis laboratory, with sample picking and loading supervision on high-value procurement.
Stage Two, Construction and Commissioning: During expansion projects, mill revamps, and furnace rebuilds, TCR provides baseline non-destructive testing on structural steel and pressure systems, welder certification and procedure qualification per ASME Boiler and Pressure Vessel Code Section IX and AWS D1.1, radiography and ultrasonic testing of critical welds, post-weld heat treatment, and positive material identification, so the rebuilt asset starts its campaign with a documented baseline.
Stage Three, In-Service: In operation, TCR deploys thermography of furnace shells, ladles, and torpedo cars for refractory hotspot detection, thickness monitoring of gas cleaning plant and ducting, remote visual inspection of stacks and confined spaces, and oxide scale and corrosion mapping on boiler and power block equipment in captive plants, with risk-based inspection planning per API RP 580 principles adapted to metallurgical plant equipment.
Stage Four, Shutdown and Turnaround: During relines, capital shutdowns, and mill stops, TCR inspects blast furnace shell welds, hood and lance systems, crane girders and structural members, reheating furnace tubes with in-situ metallographic replication, direct reduced iron reformer tubes with ARTiS (as deployed at Emirates Steel Industries on DRP1 and DRP2), and captive power boiler pressure parts, supported by turnaround inspection manpower.
Stage Five, Continuum: The engineering stage delivers failure analysis of rolls, gears, shafts, and furnace components, remaining life assessment of reheating furnaces, reformers, and captive boilers, fitness for service per API 579-1/ASME FFS-1 on pressure systems, structural stability assessment of ageing mill buildings and crane structures, and contract research including hydrogen-based direct reduced iron materials questions that carry the plant into low-carbon steelmaking.
