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:Is P750 HS the same as a standard API 7-1 non magnetic drill collar?

Not exactly. API Spec 7-1 sets the minimum at 758 MPa yield, 965 MPa tensile, 13 percent elongation and 285 to 341 HB. P750 HS is a proprietary austenitic Cr-Ni-N grade that exceeds those values through full length cold working, reaching 1104 MPa yield and 1139 MPa tensile, with permeability at or below 1.001. SHUNFU METAL supplies both the standard minimum level and the P750 HS level.

Q:What sizes and connections can SHUNFU METAL supply in P750 HS?

Finished slick and spiral collars run from 3-1/8 in to 11 in outside diameter with bores from 1-1/4 in to 3 in, at 30 or 31 ft. This listing covers 3-1/8 in with NC23 connections, about 298 kg per joint. NC26 through NC70 and REG connections are machined to API Spec 7-2 gauges. Raw stock is also available as hollow bar, forged round, flat bar and strip.

Q:What inspection and documents come with each collar?

Every collar is 100 percent hot spot tested for magnetic permeability, ultrasonically inspected over its full volume to ASTM E114, checked for sensitisation to ASTM A262 and for pitting to ASTM G48 Practice A. Threads are gauged to API Spec 7-2. SHUNFU METAL issues EN 10204 3.1 or 3.2 certificates with full heat traceability, produced under an ISO 9001 certified system.
