AI-Powered supplier vetting

SummaryHunan Shunfu Metal Material Co., Ltd. is a limited company supplying steel pipe, with 24 employees and stated annual output of 100,000 tons of oil steel products. It provides OEM and ODM services and can customize from samples or designs, but it does not provide 3D software design, has no SDK, and launched no new products in the past year. Export sales represent 71%–90% of total sales, with Southeast Asia and the Middle East identified as primary markets; however, it reports no overseas showroom, agents, branches, or offline trade-show participation. Lead time is one month in both peak and off-peak seasons. The available audit record identifies SGS as the auditor, but the stated audit result is 0 and no certification is identified. Quality and service governance evidence is weak because written procedures or records are absent for supplier approval, corrective actions, complaint handling, and service assessment. Financial records are referenced for 2021–2023, but their actual performance is not provided.

Supplier typeThe supplier is identified as Hunan Shunfu Metal Material Co., Ltd., a limited company with 24 employees whose primary and offered product is steel pipe. It is not part of a larger company group, and its stated business scope includes permitted company operations and import/export activities.

After-Sales capabilityThe supplier has no overseas showroom, agents, branches, or reported offline trade-show participation. It also has no written procedures or records for customer complaints, corrective and preventive actions, or service-capability assessment, indicating limited documented after-sales infrastructure.

R&D capabilityThe supplier is described as a professional technical supplier and offers ODM services, but it has only one year of total R&D engineer experience, no SDK, no 3D software design service, and no new products launched in the past year. These stated limitations demonstrate a deficiency in innovation resources and recent product development.

Production capacityThe supplier reports annual production of 100,000 tons of oil steel products, with one-month lead times in both peak and off-peak seasons. Its product scope is steel pipe, and the stated production information supports established manufacturing capacity, although the slices do not provide independent verification of output or quality performance.

Customization capabilityThe supplier explicitly provides customization from samples and designs, along with OEM and ODM services. This supports both customer-specified product adaptation and design-manufacturing cooperation, although 3D software design and SDK support are unavailable.

Product Q&A

Q:What is P690 non-magnetic drill collar steel?

P690 is a high pitting corrosion resistant, nonmagnetic austenitic chromium-nickel-molybdenum-nitrogen steel developed for oilfield bottom hole assemblies. It keeps relative magnetic permeability at or below 1.005, so MWD and LWD sensors read the true earth field without interference. SHUNFU METAL supplies it both as finished collars and as bar stock for customer machining.

Q:Is P690 equal to any ASTM, EN or JIS grade?

No. P690 is an oilfield proprietary grade and has no identical entry in ASTM, AMS, GOST or JIS. The nearest chemistry match is UNS S34565, also called EN 1.4565 or X2CrNiMnMoN 25-18-6-5. Mechanical properties still differ because P690 is delivered cold worked over the full length. Any substitution must be approved by your drilling engineer.

Q:What sizes, connections and delivery conditions are available?

Finished collars run from 3-1/8 in to 11 in outside diameter in 9.15 m and 9.45 m lengths, with NC or API REG connections to API Specification 7-2. Bar stock is offered as rolled round, forged round, flat bar and strip. Standard delivery is solution annealed plus full-length cold worked, with black, turned, ground or shot peened surfaces.

Q:How do you verify the non-magnetic property?

Every collar is scanned over its full length with a Foerster Magnetomat hot spot tester and the permeability printout ships with the collar. SHUNFU METAL also runs 100 percent ultrasonic testing to ASTM E114, intergranular corrosion testing to ASTM A262 Practice A and E, pitting testing to ASTM G48 Practice A, plus tensile, impact and hardness tests.

Q:What certificates come with the order and how fast is delivery?

Each shipment is released under ISO 9001 with an EN 10204 3.1 or 3.2 certificate listing melt route, heat analysis, tensile, impact, hardness, ultrasonic and permeability results. Third party witness inspection by your nominated agency is accepted. Standard sizes ship from stock in two to four weeks; made to order sizes and ESR heats take longer.
