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 a non-magnetic drill collar and why is it used?

It is a heavy BHA component made of austenitic Cr-Mn-Ni-N stainless steel with very low magnetic permeability. Placed around the MWD/LWD tools, it isolates them from the steel drill string's magnetic field so directional sensors read the true geomagnetic field and the wellbore stays on its planned path. Used in directional, horizontal and offshore wells.

Q:Which materials and standards does SHUNFU METAL supply?

We supply P530, P530 HS, P550, P580, P650, P690, P750 and P750 HS to API Spec 7-1 and SY/T 5144. Permeability is tested to ASTM A342 at 1.005 max, under an ISO 9001:2015 certified system.

Q:What sizes and connections are available?

OD from 3 1/8 in to 11 in, lengths 30-31 ft (Range 2) or custom, in slick, spiral, flex and pony styles. Connections NC23-NC77, 6 5/8 FH and 4 1/2 IF/XH. ID is shot-peened for sour-service use.
