Magnetic Flux Leakage (MFL) in Carlsbad, NM

MFL for Southeast New Mexico tank integrity

Across the Delaware Basin and the wider Southeast New Mexico oilfield corridor, storage tanks support production, gathering, terminals, and service operations. Their floors face corrosion from product-side exposure, water and sediment accumulation, and underside conditions that can vary with foundation and environment. Corrosion may be localized or widespread, making reliable floor condition data important to safe operation and practical maintenance planning.

Magnetic Flux Leakage (MFL) helps owners evaluate above-ground storage tank floors without cutting or removing the inspected plate. It can identify and map indications associated with internal and external corrosion, including wall loss and pitting. The resulting information gives integrity teams a clearer basis for prioritizing follow-up, planning repairs, and supporting fitness-for-service decisions in line with the applicable inspection program.

For Carlsbad-area operators, local delivery matters. TechCorr supports producers, midstreamers, and service companies throughout the Delaware Basin and Southeast New Mexico with rapid, certified field response, backed by advanced NDE, pipeline NDE, and rope access capabilities.

How Magnetic Flux Leakage works

MFL is an electromagnetic non-destructive testing and NDE method. A tank-floor scanner magnetizes the steel as it travels across the plate. Where corrosion or another change in the steel’s cross-section disrupts the magnetic field, sensors detect the resulting leakage. The scanner records and maps those responses so inspectors can review indications across the floor rather than rely only on isolated spot readings.

Automated scanning produces a coverage map, often presented in color, showing locations and relative signal characteristics that warrant evaluation. MFL is especially useful for screening tank-floor plate for corrosion-related wall loss. Results are interpreted by qualified personnel and should be considered with the inspection scope, equipment limitations, and applicable acceptance criteria. MFL does not replace every inspection method or determine fitness for service on its own; the owner’s engineering and inspection team decides whether confirmation, repairs, or additional assessment are needed.

Because it is non-destructive testing, MFL supports condition assessment while preserving the inspected plate. Its mapped results can help focus follow-up work and create a more actionable record for asset integrity planning.

What TechCorr’s Carlsbad team delivers

TechCorr coordinates MFL tank-floor inspection around the site’s operating requirements, access constraints, and inspection objectives. The work begins with scope alignment: understanding the tank and inspection history, clarifying the requested coverage, and coordinating safe access and the conditions needed for scanning. Field execution then uses an MFL scanner to systematically survey the floor and capture indications for review.

The deliverable is intended to help the owner understand where corrosion-related signals occur and where further attention may be warranted. TechCorr can support clear communication of inspection findings to operations, maintenance, and integrity stakeholders so they can connect the results to repair planning, additional evaluation, or future inspection intervals. Scope, reporting detail, and any complementary NDT or NDE methods are defined for the asset and project rather than assumed to be identical for every tank.

Carlsbad’s broader capabilities are valuable when inspection needs extend beyond tank floors. Advanced NDE and pipeline NDE expertise can support related assessment needs, while rope access provides another option for work in elevated or difficult-to-reach locations where appropriate. This combination helps regional operators coordinate inspection resources through one field-service partner.

Standards, qualifications, and inspection programs

Tank inspection requirements depend on the asset, owner’s procedures, jurisdiction, and the agreed scope. API 653 is a key standard for inspection, repair, alteration, and reconstruction of above-ground storage tanks, and it provides important context for tank-floor assessment. API 510 addresses pressure-vessel inspection, while API 570 covers piping inspection; they are relevant to broader facility integrity programs but are not substitutes for the applicable tank requirements. TechCorr aligns inspection planning and reporting with the standards and owner requirements identified for the specific work.

Personnel qualifications also matter. ASNT practices and employer-based qualification programs help establish appropriate training, experience, and certification for NDT personnel and methods. NACE International, now AMPP, provides corrosion-focused standards and resources that may inform corrosion control and integrity programs. ISO standards may apply to quality management, inspection processes, or customer-specific requirements. Applicability varies by project; the asset owner should confirm the governing documents and acceptance criteria before inspection.

MFL findings are inspection data, not an independent engineering disposition. Integrity decisions should consider method limitations, corroborating information, tank history, and the owner’s engineering evaluation. This disciplined use of NDT and NDE results helps make asset integrity decisions more transparent and defensible.

Why TechCorr Carlsbad

TechCorr brings advanced NDE, pipeline NDE, and rope access strength to the South Central region, with field response based in Carlsbad for Delaware Basin and Southeast New Mexico operations. Our focus is practical inspection support: qualified personnel, a defined scope, careful data collection, and results that help integrity teams plan next steps. We do not assume every tank or site has the same conditions; we coordinate the work around the owner’s needs and applicable requirements.
