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 P550 and where is it used?

P550 is a high-nitrogen austenitic manganese-chromium stainless steel for non-magnetic drill collars. Its relative permeability stays at or below 1.005, so it shields MWD and LWD sensors from drill string interference. It is used in oil, gas, geothermal, coalbed methane and exploration drilling.

Q:Which standards do your collars meet?

SHUNFU METAL manufactures to API Spec 7-1 and SY/T 5144. Permeability is measured to ASTM A342, ultrasonic testing to ASTM E114 and intergranular corrosion to ASTM A262 Practice A and E. Material documents are issued to EN 10204 3.1 or 3.2.

Q:What sizes and connections are available?

Finished collars range from 3-1/8 in to 11 in OD in Range 2 or Range 3 lengths, slick or spiral. Connections cover NC38 to NC50, 4-1/2 IF, 6-5/8 REG and 7-5/8 REG, plus double-shoulder designs. Bar stock is supplied from 80 mm to 800 mm.

Q:How is the non-magnetic property verified?

Every collar is scanned over its full length by magnetic hot-spot testing, and the printed permeability trace is delivered with the product. The bore gradient is held within 0.05 microtesla. Certificates are archived under our ISO 9001 system.

Q:What are the delivery and surface conditions?

Standard delivery is warm forged, quenched, solution annealed and cold worked over the full length. Surfaces are supplied black, rough turned, peeled, ground or shot peened, with honed bore and cold rolled, phosphated or copper plated threads.
