AI-Powered supplier vetting

SummaryJIANGSU LIANGYI CO., LIMITED is identified as a China-based manufacturer/factory in Jiangsu serving metallurgy, minerals, energy, petroleum, chemical, power-generation, shipbuilding, and heavy-machinery applications. The supplier reports 50 R&D engineers, 50 quality-control staff, seven production lines, and a production system covering melting, remelting, forging, casting, heat treatment, machining, and inspection. Its product information includes special-alloy grades, forged and rolled products, and oilfield-related swage, sleeve, and pocket components. Trade records show shipments to India, Mexico, and identified buyers, but the supplied information does not establish certifications, after-sales arrangements, financial credibility, or a clearly documented customization process.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and describes itself as a special-alloy material supplier established in 1997, with products used in petroleum, chemical, power-generation, and shipbuilding industries. This supports a direct manufacturing identity rather than a purely trading profile.

R&D capabilityThe supplier reports 50 R&D engineers and lists a broad range of special-alloy grades. Its workshop includes vacuum melting and electroslag remelting capabilities, indicating technical materials-processing resources, although no specific patents, new-product achievements, or documented R&D outcomes are stated.

Production capacityThe supplier reports seven production lines, 50 quality-control staff, and an integrated system covering vacuum melting, electroslag remelting, forging, casting, heat treatment, machining, and inspection. Its listed forged rings, shafts, flanges, pipes, stainless-steel bars, and oilfield components further support broad production capability.

Client casesTrade records associate the supplier with PARVEEN INDUSTRIES PVT LTD, TURBOMAQUINAS SA DE CV, and PRIMETALS TECHNOLOGIES MEXICO S DE RL DE CV, with shipments to India and Mexico. This provides identifiable customer and export references, although the limited records do not establish project outcomes, duration, or customer satisfaction.
