AI-Powered supplier vetting

SummaryThe supplier manufactures specialized equipment for oil refining and chemical production and also conducts hardware product manufacturing, research and development, sales, and related services. It reports ISO 9001 and ISO 14001 certification, two production lines, six to ten quality-control staff, and six to ten years of total R&D engineer experience. The supplier offers broad customization, OEM, and ODM services, with documented inspection, corrective-action, complaint-handling, and traceability procedures. Export experience is stated as 15 years, with 51%–70% of total sales from exports and self-operated import/export rights. However, it has no overseas agents or branches, warehouses, showrooms, or SDK availability; it also reports no new products in the past year and no valid manufacturing-capacity contract with related subcontractors. Customer cases are not specifically provided.

Supplier typeThe stated business scope includes manufacturing and sales of specialized equipment for oil refining and chemical production, hardware product manufacturing, hardware R&D, and ferrous metal casting. The company description also covers material purchasing, production, inspection, delivery, and after-sales service, indicating a manufacturer with integrated related operations.

CertificationsThe supplier reports holding ISO 9001 and ISO 14001 certifications. These are explicit certifications relevant to quality and environmental management systems.

After-Sales capabilityThe supplier states that its operations include after-sales service and has clear, followed procedures and records for handling customer complaints and corrective and preventive actions. However, it reports no overseas agents or branches and offers overseas services in zero countries, which limits directly evidenced overseas service coverage.

Production capacityThe supplier operates two production lines, maintains six to ten quality-control staff, has in-stock service capacity, and uses documented inspection, supplier assessment, corrective-action, complaint-handling, quality-assurance, and material-traceability procedures. Nevertheless, it reports no valid contract with associated subcontractors for manufacturing capacity, creating a documented weakness in subcontracting governance.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also provides OEM services for well-known brands and ODM services, demonstrating broad stated customization and manufacturing-design support.

Product Q&A

Q:Which media can this safety relief valve handle?

It is designed for air, ammonia, petroleum gas, and corrosive gas or liquid media. Specific models like KGAA21Y are optimized for liquefied petroleum gas.

Q:What materials are used for the main parts?

Main parts are made from materials such as 2Cr13, 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti, 50CrVA, and Q235-A, depending on the specific model (A21H-C, A21W-P, A21Y-R) and required corrosion resistance.

Q:How does the low lift design affect performance?

In low lift valves, the disc lifts only a small distance (1/24th of bore diameter), resulting in lower discharge capacities compared to full or high lift valves, suitable for specific pressure protection needs.

Q:What are the payment terms and lead times?

Payment terms include LC, T/T, Western Union, and Money Gram. Lead time is within 15 workdays off-season and one month during peak season.

Q:Is customization available for this valve?

Yes, the product category is Safety Valve with automatic actuator and threaded connecting type. Customization options exist for specific industrial applications involving air, ammonia, or petroleum gas.
