AI-Powered supplier vetting

SummaryShanghai Baori Steel Industries Co., Ltd. is a limited company with three employees, offering Spring Steel Cold Coin and a broad range of hardware, building-material, ceramic, timber, automotive, motorcycle, and general merchandise products. It reports flexible customization and one year of export experience, but no ODM, popular-brand OEM, SDK, or new-product launches during the past year. Service coverage is limited: it has no stock, overseas warehouse, showroom, agent, or branch, and serves zero overseas countries according to the provided data. Peak- and off-season lead times are stated as within 15 workdays to one month. Quality-system evidence is incomplete, with zero listed quality-control testing equipment and unknown quality assurance and traceability status. An audit by TÜV Rheinland is recorded, but the audit result is shown as 0 and the report validity ended on 2025-10-14. No customer cases or offline trade-show participation are provided.

After-Sales capabilityThe supplier has 10 qualified service suppliers and accepts FOB, CIF, and CFR quotation terms plus LC and T/T payment terms. Nevertheless, it has no stock, overseas warehouse, showroom, agent, or branch; it has served zero overseas countries in the provided data, and its service corrective/preventive-action mechanism lacks written procedures or records.

R&D capabilityThe supplier launched no new products during the past year and does not provide ODM services, popular-brand OEM services, or an SDK. One R&D engineer is listed, but the stated responsibility is handling product photos, which does not demonstrate substantive product-development capability.

Production capacityThe supplier offers flexible customization and reports lead times ranging from within 15 workdays to one month in both off- and peak-season statements. However, it has only three employees, no in-stock capacity, zero listed quality-control testing equipment, and unknown quality-assurance and traceability status, indicating explicit production and quality-control limitations.

Customization capabilityThe supplier explicitly reports flexible customization for its Spring Steel Cold Coin offering. The provided slices do not specify customization scope, tooling, technical resources, or delivery conditions, but the stated capability is direct evidence of customization availability.

Product Q&A

Q:What is the main difference between Tubing and Casing?

Casing is installed during drilling to support the well structure, prevent collapse, isolate formations, and protect freshwater zones. Tubing is run inside the casing after completion and serves as the primary conduit for transporting oil and gas from the reservoir to the surface.

Q:What standards do Tubing and Casing comply with?

Products are manufactured in accordance with API 5CT standards. Additional international or customer-specific requirements, including special inspection, testing, and certification, can be met upon request.

Q:What steel grades are commonly available?

Common grades include J55, K55, N80, L80, P110, C95, T95, and Q125. For corrosive or sour service environments, options like 13Cr, stainless steel, and special alloys are available.

Q:What connection types can be supplied?

We supply API connections such as NU, EU, STC, LTC, and BTC, as well as premium connections featuring metal-to-metal sealing for high-pressure and high-temperature applications.

Q:How do customers select the correct Tubing and Casing?

Selection depends on well depth, pressure, temperature, production rate, and environmental conditions. Key factors include pipe size, wall thickness, steel grade, and connection type. Technical support is provided to assist in choosing the suitable solution.
