Key features

High-Torque Rotary Table Drive: Precision roller chain assemblies transmit massive drilling torque from draw-works to rotary tables, maintaining synchronized rotation under the punishing loads

Chain Fatigue Failures Solved: Eliminate catastrophic drilling downtime from elongated chains; shot-peened link plates and case-hardened pins resist the extreme pulsating loads of tripping pipe

Spec 7F Certified: Manufactured to American Petroleum Institute standards with certified tensile strength ratings, ensuring compliance with global oilfield safety and performance requirements.

Rig Floor to Mud Pump Ready: Engineered for draw-works drives, rotary tables, mud pump transmissions, and cathead systems-performs reliably in desert heat, arctic cold, and offshore salt-spray environ

Industrial Roller Chains: Unlike standard industrial chains, oil field chains are designed for 2x the shock load capacity with multi-strand configurations, meeting the zero-failure demands of 24-hour

AI-Powered supplier vetting

SummaryHangzhou Ocean Industry Co., Ltd. is a China-based trading company established in 2005, focused on power-transmission and related industrial products including chains, sprockets, gears, racks, pulleys, couplings, and reducers. It reports broad export coverage, export activity since 2018, and one-month order fulfillment in both peak and off-peak periods. The supplier claims ISO9001-compliant production procedures, after-sales service, engineering support, non-standard product design, and more than 10 production lines, although the available information does not independently verify these claims. Its manufacturing area and employee count are limited in the provided data, and no clear customer case details or financial-credit evidence are supplied. One trade record describes a gas-stove product, which is not aligned with the supplier’s stated primary product range and should be clarified.

Supplier typeThe supplier is explicitly identified as a trading company or limited company, headquartered in Hangzhou, China, and associated with industrial trading categories. Its stated product range centers on transmission components and machinery-related goods.

After-Sales capabilityThe supplier explicitly claims prompt response, engineering support, and good after-sales services, and states that it provides customer information and samples with a quick reply. These statements indicate declared service capability, but no service metrics, team structure, or verified customer outcomes are provided.

R&D capabilityThe supplier states that it can design and manufacture non-standard products to meet special customer requirements. This supports some customization-oriented engineering capability, but the slices do not provide examples, patents, research resources, or validated innovation results.

Production capacityThe supplier reports a 440.0 m² manufacturing plant, more than 10 production lines, 6–10 quality-control staff, a broad industrial product range, and a one-month lead time in both peak and off-peak periods. These data support stated production and fulfillment capability, although the supplier is also classified as a trading company and the reported production scale is not independently verified.

Customization capabilityThe supplier explicitly states that it can design and manufacture non-standard products for customers’ special requirements. This is direct evidence of customization capability, though no technical examples, tooling details, or completed customized projects are supplied.
