AI-Powered supplier vetting

SummaryThe supplier is a petroleum-machinery manufacturer and seller covering valves, Christmas trees, wellhead equipment, blowout preventers, manifolds, and related drilling and production accessories. It reports professional technical R&D capability, 3D software design, sample-based customization, and ODM services, but no new products in the past year, no SDK, and only two R&D engineers. Manufacturing-related evidence includes CNC machining, inspection equipment, inventory capability, contracts with associated subcontractors, and approximately one-month lead times in both peak and off-season. Service procedures exist for corrective actions and complaint handling, while supplier-capability assessment procedures lack completed records. The supplier reports one year of free after-sales service and provision of English material and pressure-testing reports. Certification details, financial performance, and customer case evidence are insufficient or limited; no Fortune 500 cooperation is reported.

Supplier typeThe supplier is a professional technical manufacturer and seller of petroleum machinery, including valves, wellhead equipment, blowout preventers, manifolds, and related accessories. Its capabilities also include CNC machining and design services, indicating a manufacturing-oriented technical supplier rather than a pure distributor.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints. It also states that it provides English material-testing and pressure-testing reports and guarantees one year of free after-sales service, supporting a positive after-sales service assessment.

Production capacityProduction evidence includes CNC machining, a tungsten carbide workshop, heating and machining equipment, complete inspection and measurement devices, inventory capability, valid contracts with associated subcontractors, and stated one-month lead times in both peak and off-season. Finished products are checked by packing staff, while the supplier-capability assessment procedure has written procedures but no records, indicating substantial capacity evidence with some process-verification limitations.

Customization capabilityThe supplier explicitly provides customization from samples, 3D software design services, ODM services, and design and fabrication. These statements directly support the supplier's ability to develop customized products based on customer requirements.

Product Q&A

Q:What is the difference between Upper and Lower Kelly Cock Valves?

The Upper Kelly Cock Valve features left-hand (LH) thread and connects to the top of the Kelly. The Lower Kelly Cock Valve has right-hand (RH) thread and connects to the bottom of the Kelly. Both are ball valves with similar structures.

Q:How does the Kelly Cock Valve operate?

It is a manually operated ball-type valve. You can open or close it by turning the special operating wrench 90 degrees according to the indicating direction. It keeps the hole unblocked in the 'on' position and seals the internal bore in the 'off' position.

Q:What working pressure options are available?

Customers can specify the working pressure when ordering. The available options are 5,000 PSI, 10,000 PSI, and 15,000 PSI.

Q:What is the sealing principle of this valve?

The ball is positioned and provided with proceeding stress by the lower seat supported by spring load. This creates a close seal between the ball and the ball seat, preventing kicks or blowouts under high pressure.

Q:What customization options are provided?

Customization from samples is available. When ordering, please specify the type (Upper or Lower), Tool OD, Working Pressure, and Tool connection.
