What Testex does

TesTex Japan (有限会社 テステックス・ジャパン) is a private Japanese non-destructive testing (NDT) company specializing in electromagnetic inspection of industrial infrastructure — principally oil refineries, petroleum plants, and petrochemical facilities. Established in August 1998 as a joint venture with TesTex USA (Pittsburgh, Pennsylvania), the company holds exclusive Japanese rights to Low Frequency Electromagnetic Induction Testing (LFET / 低周波電磁誘導法) technology, which enables non-contact detection of wall thinning, corrosion, and defects on both interior and exterior surfaces of steel plates and pipes, including through coatings, rust, and deposits. Headquartered in Hiroshima with a regional branch office in Kawasaki (Yokohama), TesTex Japan is led by Representative Director Kimoto Sanshirō (木本 三四郎) and is organized as a 有限会社 (limited liability company) with ¥30 million in registered capital.

The company's core product portfolio is built on four proprietary platforms: the Falcon 2000, a 64-coil LFET scanner with 310mm effective width (Sr.) and a 16-coil 100mm variant (Jr.) for comprehensive tank bottom, side, and pipe inspection at up to 4500mm scanning speed with ±5mm position accuracy; the Line-Cat, a 64-sensor high-speed pipe inspection device capable of inspecting 100m+ per day across large-diameter piping including bent and spiral pipes; the Eagle 2000, a Remote Field Testing (RFET) system for boiler tubes and heat exchanger tubes in diameters from ϕ12mm to ϕ82mm, including magnetic materials where conventional eddy current testing fails; and the TORITON Ⅱ BFET, a Balance Field Eddy Current system for weld inspection through coating without surface preparation. Three newer inspection solutions — Falcon Spider, NOBORU Ⅳ (self-propelled remote UT device), and YUKA-ZOU (tank roof inspection technology) — were launched in February–April 2026, extending coverage to tank side plates, continuous UT measurement, and tank roofs. Disclosed operational throughput is approximately 80m/day for Line-Cat, 40m²/day for Falcon 2000, and roughly 18km/year of off-site crude oil piping inspection.

TesTex Japan operates a direct enterprise field-services model, dispatching trained technicians with proprietary equipment to customer facilities for on-site inspection campaigns. Pricing is custom-quoted based on inspection scope, equipment deployed, pipe diameter, and facility conditions; multi-year service contracts are noted. Customers are concentrated in the oil refinery and petrochemical verticals in Japan, with service coverage extending across Kansai-region and Greater Tokyo-area refineries. Marketing is primarily website- and technical-publication-driven, including case studies, downloadable PDFs, and articles in the Japanese Society for Non-Destructive Inspection journal and Nikko Publishing's Inspection Technology magazine. The company maintains no disclosed external institutional investment and is privately held by the joint venture partners.

Core offering

TesTex Japan delivers on-site non-destructive testing (NDT) services for petroleum refineries and petrochemical plants, using proprietary Low Frequency Electromagnetic Induction Testing (LFET) equipment to inspect storage tank bottom/side/roof plates, piping systems, boiler tubes, and heat exchanger tubes for corrosion and wall thinning. The company both deploys this equipment in field inspection services and supplies dedicated LFET/RFET/BFET inspection systems for industrial infrastructure in Japan under exclusive license from TesTex USA.

Product overview

TesTex Japan provides a portfolio of non-destructive testing equipment and inspection services based on electromagnetic induction technologies. The core product line includes the Falcon 2000 for comprehensive tank and pipe inspection, Line-Cat for high-speed pipe wall thickness measurement, Eagle 2000 for boiler tube inspection using remote field testing, and TORITON Ⅱ BFET for weld inspection. These systems work alongside complementary solutions like Falcon Spider and NOBORU Ⅳ for tank side plate inspection, and YUKA-ZOU for tank roof inspection. The company operates as a joint venture with US-based TesTex, leveraging Low Frequency Electromagnetic Induction Testing (LFET) technology to detect corrosion and wall thinning in industrial infrastructure without requiring contact or surface preparation.

Direct peers

• Mistras Group: US-headquartered pure-play NDT services and technology company serving refineries, pipelines, and industrial assets. Highly comparable business model to TesTex Japan, with proprietary NDT methods and on-site inspection delivery.
• Eddyfi Technologies (including NDT Global): Provider of advanced NDT equipment and pipeline inspection services using electromagnetic, ultrasonic, and other technologies. Closely comparable to TesTex Japan's LFET-based pipeline and tank inspection approach.
• Rosen Group (ROSEN): Pipeline integrity services and inspection technology provider for the oil & gas industry. Comparable to TesTex Japan's high-speed piping corrosion and wall-thinning inspection offering for crude oil and process piping.
• Applus+: Global NDT and asset integrity inspection services provider with significant exposure to oil & gas, refining, and petrochemical infrastructure — directly comparable to TesTex Japan's core service offering, though at much greater scale and geographic reach.

Broad incumbents

• SGS: Swiss-based global TIC company offering industrial inspection, NDT, and asset integrity services. Broadly comparable customer base (refineries, petrochemicals, industrial plants) but operates at vastly larger scale.
• Olympus (Evident Scientific): Major NDT equipment manufacturer (ultrasonic, eddy current, remote visual inspection) supplying industrial asset inspection. Comparable to TesTex Japan on the NDT equipment side (Falcon, Line-Cat) though not on services.
• Intertek: UK-based TIC provider with industrial inspection services for energy and process industries. Comparable in serving refinery and petrochemical end markets, though TesTex Japan is far more specialized in LFET.
• Bureau Veritas: Global testing, inspection, and certification (TIC) conglomerate with significant industrial asset integrity and NDT services. Overlaps with TesTex Japan's tank and piping inspection but as part of a much broader TIC portfolio.

Regional players

• JFE Techno-Research: Japanese engineering services firm providing NDT, materials testing, and inspection for steel and energy infrastructure. Direct regional comparable serving the same Japanese refinery and steel-industry customer base.
• Nihon Denshi Sokki (JEOL NDT) / Fujifilm NDT: Japanese NDT equipment and inspection solution providers serving domestic industrial and energy markets. Comparable regional competitor to TesTex Japan in the Japanese inspection ecosystem.
