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 material as P750 or P550?

No. P750 HS sits at the top of the same non-magnetic family. P550 replaces nickel with about 20 percent manganese and reaches 140 ksi yield. P750 delivers 140 ksi with much better corrosion resistance from around 29 percent nickel. P750 HS adds a heavier full length cold work pass, lifting yield to 160 ksi at 10 percent elongation. The nickel level is what makes it the safer choice in chloride bearing and sour mud systems.

Q:Can you supply the 6.5 in collar with NC50 and other configurations?

NC50 is the standard connection for 6.5 in OD, and we also cut NC46, 5-1/2 FH, NC56 and REG. Standard bore is 2-13/16 in at about 93 lb/ft; a 2-1/4 in bore gives about 100 lb/ft. Collars ship slick or spiral in API Range 2 lengths with rolled thread roots, phosphate or copper plating, thread protectors and NC50 gauging to API Spec 7-2.

Q:What inspection and certification come with each collar?

Every collar receives 100 percent ultrasonic inspection to ASTM E114, hot spot permeability testing with a Forster Magnetomat probe, sensitisation testing to ASTM A262 Practice A and E, and pitting verification to ASTM G48 Practice A. You receive the permeability printout, dimensional record, mechanical test results and EN 10204 3.1 or 3.2 certificate with full heat traceability. Third party inspection to DS-1 or NS-1 is available on request.
