TCR Japan (A Chugai Technos Alliance)
Two independent inspection houses, one testing materials in Mumbai since 1973 and one serving Japanese industry from Hiroshima since 1953, now working as one company in Japan. ARTiS reformer tube inspection is where it starts, not where it stops.
1973年創業の TCR と1953年創業の中外テクノス株式会社様。日本のアセットオーナーの皆様に、材料試験・非破壊検査・アセットインテグリティを一体でご提供します。
Request a QuoteWhat TCR brings to Japan
TCR Engineering serves Japan through an alliance with Chugai Technos Corporation of Hiroshima, under a memorandum of understanding signed on 29 April 2026. Materials testing, non-destructive testing, asset integrity and failure investigation run under TCR's NABL ISO/IEC 17025:2017 accreditation in Navi Mumbai. ARTiS reformer tube inspection mobilises to Japanese sites.
TCR Engineering Services は、広島の中外テクノス株式会社様との業務提携（2026年4月29日締結の覚書）を通じて日本市場にサービスをご提供します。材料試験、非破壊検査、アセットインテグリティ評価、破損解析は NABL ISO/IEC 17025:2017 認定（登録番号 NABLT0726MH18640）のもとで実施し、ARTiS リフォーマー管検査は日本国内の現場へ出張対応いたします。
- One accredited signature. NABL ISO/IEC 17025:2017, certificate NABLT0726MH18640, 1,483 accredited test methods, accepted in more than 90 economies under the ILAC mutual recognition arrangement.
- A Japanese interface. Contracting, site coordination and day-to-day communication run through Chugai Technos in Hiroshima, so a Japanese asset owner deals with a Japanese company.
- Two-way, not a distribution deal. Chugai's Scale Checker and drone inspection are going into India and the Gulf in the same agreement.
- ARTiS is the entry point, not the boundary. The full TCR catalogue is available to Japanese owners from day one.
- No office, and we say so. Japan is served through the alliance; samples are tested at the accredited laboratory in Navi Mumbai.

Two houses of similar vintage, and what the alliance carries in both directions ／ 中外テクノス様との提携
Chugai Technos Corporation of Hiroshima was founded in 1953. TCR Engineering was founded in Mumbai in 1973. Both are independent, technically-led inspection houses that outlasted three generations of competitors in a sector dominated by global conglomerates, and both stayed independent for the same reason: they invested in customer relationships over decades rather than quarters. The memorandum of understanding signed on 29 April 2026 between TCR Engineering Services Pvt. Ltd., Chugai Technos Corporation and Chugai Technos India Pvt. Ltd. of Bengaluru is two years, project-based, non-exclusive, and deliberately two-way.
中外テクノス株式会社様は1953年、TCR Engineering は1973年の創業です。いずれも独立系の技術主導型検査会社として、両社ともお客様との関係に数十年単位で投資してきました。2026年4月29日締結の覚書は2年間・案件ベース・非独占であり、双方向の枠組みです。
- ARTiS reformer tube inspection, the entry point.
- AiOM, asset integrity and optimisation management: damage-mechanism taxonomy, inspection planning and the corrosion-intelligence layer that carries findings from one turnaround to the next.
- Fitness-for-service to API 579-1 / ASME FFS-1, Level 1 to Level 3.
- Sour service testing: HIC to NACE TM0284, SSC to NACE TM0177 Methods A to D, qualification to NACE MR0175 / ISO 15156.
- Fracture toughness: CTOD to BS 8571 and ISO 15653, K1c to ASTM E399, J-integral to ASTM E1820, crack growth to ASTM E647.
- Creep and stress rupture to ASTM E139, including accelerated creep rupture for boiler and reformer tube remaining-life work.
- Robotic radiographic crawlers and robotic tank inspection, from a base of 2,600+ km of pipeline radiography.
- Failure investigation and boiler audit, from 9,000+ group investigations.
- The Scale Checker. A radioisotope system that measures scale, sludge and fouling inside a live pipeline without removing insulation or stopping flow. TCR is taking it into two markets: power generation, where internal oxide scale on boiler tubes governs remaining life, and refining and petrochemicals, where fouling governs throughput.
- Drone structural inspection. Bridges, tanks, flare stacks and heritage structures, with crack detection to 0.2 mm, alongside TCR's own record of 500+ bridge inspections across India.
- Japanese-grade environmental and emissions testing. Stack and ambient monitoring, AIG, SCR, APH, ESP and FGD performance testing, PFAS analysis and greenhouse-gas inventory work, as Indian CPCB norms and Saudi NCEC standards tighten.
Most cross-border inspection alliances exchange test methods. This one exchanges an operating system as well. The wider context is on the alliances page, and the full announcement is at TCR Engineering and Chugai Technos sign MOU.
From the President
TCR has been testing materials since 1973 and Chugai Technos has been serving Japanese industry since 1953. Neither of us was bought, merged or rolled up along the way, and that is not luck. Both firms stayed independent because they invested in customers over decades rather than quarters, and both are still run by people who came up through the technical work.
We are complementary, not competing. Chugai knows the Japanese asset owner and the Japanese way of working. We know the metallurgy behind the decision, and we have nine thousand failure investigations to argue it from. Put those two together and the customer gets a better answer than either of us could give alone.
I want this alliance to read as what India and Japan can build together, and to still be running in twenty years. That is the standard we are holding ourselves to, not the first purchase order.
TCR は1973年から、中外テクノス様は1953年から、それぞれ独立を保ってきました。両社は競合ではなく補完関係にあります。この提携が、日印両国が共に築けるものの象徴となり、二十年後も続いていることを願っています。
What TCR does for a Japanese asset owner ／ 日本のお客様へのサービス範囲
ARTiS is the reason for the first conversation. It is not the boundary of the relationship. TCR runs six service pillars out of an NABL ISO/IEC 17025:2017 accredited laboratory with 1,483 accredited test methods, and every one of them is available to a Japanese owner through Chugai Technos from day one.
ARTiS は最初のご相談のきっかけであり、ご提供範囲の上限ではありません。TCR は NABL ISO/IEC 17025:2017 認定試験所（認定試験方法 1,483件）を基盤に、6つのサービス領域を展開しています。
- 01Materials Testing ／ 材料試験Mechanical, chemical, metallurgical, corrosion, creep, fatigue and fracture toughness. Positive material identification and weld procedure qualification.materials-testing
- 02Non-Destructive Testing ／ 非破壊検査Phased array, TOFD, radiography including digitisation of film, eddy current array, IRIS, MFL, and 2,600+ km of pipeline radiography behind it.non-destructive-testing
- 03Asset Integrity ／ アセットインテグリティARTiS, AiOM, fitness-for-service to API 579-1, remaining life assessment, risk-based inspection, boiler audit and in-situ metallography.asset-integrity

- 06Inspection Manpower ／ 検査要員派遣Third-party and source inspection, vendor surveillance, expediting and shutdown inspection teams, deployed across seven countries.inspection-manpower
Behind all six sit the two things a Japanese engineer will ask about first: an accredited laboratory, and a failure investigation practice with more than 9,000 cases on record, including 1,500+ boiler tube failures. The company has been doing this since 1973 and holds NADCAP AC7101 accreditation for aerospace materials testing at two laboratories.
ARTiS, the first service into Japan ／ 日本市場への第一歩、ARTiS
ARTiS is a robotic crawler that clamps at platform level, climbs each radiant reformer tube and takes four measurements over its full length in a single pass. The output is a Level 3 assessment to API 579-1 / ASME FFS-1 Part 10 with a retirement date for every tube, not a pass or a fail. Tube outer diameters from 105 to 190 mm, to a climbing height of 15,000 mm.
ARTiS は、プラットフォーム階で管を掴んで自走し、放射部の全長を一度の走査で4項目測定するロボットクローラーです。成果物は API 579-1／ASME FFS-1 Part 10 に基づくレベル3評価であり、合否判定ではなく管ごとの交換時期をご提示します。適用外径は105〜190 mm、登坂高さは最大15,000 mm です。

| Scaffolding | Required | None, the crawler climbs | Erection cost and critical-path delay removed |
| Reporting resolution | 6 ft (1.8 m) segments | Continuous, every 100 mm | 18x granularity |
| OD measurement | 1 or 2 spot checks per tube | Every 100 mm, full length | Finds localised bulging that spalling masks |
| Bowing | Visual estimate | 5 to 200 mm, gyro digital | An objective number against OISD and API |
| Analytical output | Pass or fail judgement | API 579-1 Level 3 retirement date | Answers when, not whether |
The full method, the damage mechanisms, the five-step assessment flow, the damage-class scheme and the technical specification are set out on the ARTiS service page, in the launch article ARTiS comes to Japan, and in the twenty-one slide technical presentation in the Documents section below, available in English and Japanese.
Taking ARTiS to Japanese refiners ／ 日本の製油所への展開
Naoshi Kawabe and the Chugai Technos team have presented ARTiS to Japan's major refiners in person: Idemitsu Kosan, Fuji Oil, Toa Oil and Cosmo Oil. JFE Engineering has expressed interest from a maintenance standpoint. The photographs below are the alliance being built the way both companies believe it has to be built: in the room, in front of the people who own the turnaround.

Japan has no ARTiS installation yet, and we do not claim one. The record behind the technology is Indian and international: more than 100 reformer tube assignments, over 80 of them using ARTiS, more than 50,000 tubes scanned, and a reference base of 100,000+ in-situ replica microstructures read by in-house metallographers. That record is what the Japanese programme is being built on.

Frequently asked questions ／ よくあるご質問
ARTiS は何に答えるのですか。 / What question does ARTiS actually answer?
It returns a retirement date for each tube rather than a pass or a fail. The assessment is Level 3 to API 579-1 and ASME FFS-1 Part 10, and it carries accumulated creep damage, effective tube metal temperature and remaining life tube by tube. ARTiS は合否判定ではなく、管ごとの交換時期をご提示します。
100本の検査にどれくらいかかりますか。 / How long does an ARTiS inspection take?
Two days for 100 tubes, against four to five days for a manual scan including access. No scaffolding is required, because the crawler clamps at platform level and climbs the tube it is inspecting. 100本で2日、足場は不要です。
適用できる管の寸法と材質は。 / Which tube sizes and materials are covered?
Tube outer diameters from 105 to 190 mm, to a climbing height of 15,000 mm. Materials include HP modified micro-alloyed grades, G4852 Micro, KHR35CT, HP39W, IN519, HK40 and proprietary alloys such as Manaurite XM. 適用外径は105〜190 mm、登坂高さは最大15,000 mm です。
日本ではどのように提供されますか。 / How is the service delivered in Japan?
Chugai Technos Corporation of Hiroshima coordinates field deployment under a memorandum of understanding signed on 29 April 2026. Assessment and laboratory work runs under TCR's NABL ISO/IEC 17025:2017 accreditation, certificate NABLT0726MH18640, whose reports are accepted in more than 90 economies under the ILAC mutual recognition arrangement. 現場展開は中外テクノス様が調整します。
JIMA 2026 のどこで見られますか。 / Where can I see ARTiS at JIMA 2026?
At the Chugai Technos stand at Tokyo Big Sight, East Halls 1 to 3, from 16 to 18 September 2026, 10:00 to 17:00. Crawler hardware and a sample Level 3 assessment report will both be on the stand. 東京ビッグサイト東1〜3ホール、中外テクノス様ブースにて。
なぜ光高温計の測定値を使わないのですか。 / Why does ARTiS not trust the measured tube metal temperature?
Optical pyrometers depend on emissivity, which falls from about 0.9 on a new rough tube towards 0.6 as the surface oxidises, so the measured value drifts away from the real one. ARTiS back-calculates the effective temperature from the damage actually present, using the Larson-Miller parameter.
TCR は日本に事務所を持っていますか。 / Does TCR have an office in Japan?
No. Japan is one of the group's seven operating countries and is served through the alliance with Chugai Technos Corporation of Hiroshima. Samples from Japan are tested at the NABL ISO/IEC 17025:2017 accredited laboratory in Navi Mumbai, certificate NABLT0726MH18640. TCR は日本に自社事務所を有しておりません。
2026年4月29日に何が締結されましたか。 / What was signed on 29 April 2026, and with whom?
A memorandum of understanding between TCR Engineering Services Pvt. Ltd., Chugai Technos Corporation of Hiroshima, founded 1953, and Chugai Technos India Pvt. Ltd. of Bengaluru. It is a two-way agreement: TCR testing and asset integrity work reaches Japanese asset owners, and Chugai drone inspection, the Scale Checker and environmental testing reach Indian and Gulf owners.
中外テクノス様の技術はインドで何に使われますか。 / Which Chugai capabilities reach India and the Gulf?
Three that complement rather than overlap TCR's own catalogue: drone structural inspection of bridges, tanks, flare stacks and heritage structures with crack detection to 0.2 mm; the Scale Checker, a radioisotope system that measures scale, sludge and fouling inside live pipelines without removing insulation or stopping flow; and Japanese-grade environmental and emissions testing.
ARTiS 以外に何を依頼できますか。 / What can a Japanese owner ask TCR for beyond ARTiS?
The whole catalogue. Materials testing, non-destructive testing, asset integrity, robotic inspection, civil and infrastructure testing and inspection manpower, from a laboratory holding NABL ISO/IEC 17025:2017 with 1,483 accredited test methods and NADCAP AC7101 for aerospace materials testing. ARTiS is the entry point, not the boundary. 材料試験・非破壊検査・アセットインテグリティなど、全サービスをご利用いただけます。
報告書は日本語で提供されますか。 / In what language is the work delivered?
TCR's inspection engineers work in English. Day-to-day communication with the site runs in Japanese through Chugai Technos, who also hold the contract and the invoicing, so the owner deals with a Japanese company throughout. Key technical material is issued in writing with a Japanese translation. 契約・請求・現場調整は中外テクノス様が国内で一元対応し、重要な技術情報は日本語訳を付して書面でご提供します。
日本のお客様はどのように始めればよいですか。 / How does a Japanese client start?
Through the Request a Quote form on this site, or through Naoshi Kawabe at Chugai Technos in Hiroshima on n.kawabe@chugai-tec.co.jp. Samples are shipped to the Navi Mumbai laboratory; ARTiS reformer inspection and asset integrity scopes are mobilised to site.
