Supplier typeThe supplier is identified as a petroleum machinery manufacturer integrating R&D, production, sales and services, with a stated focus on downhole motors and petroleum equipment. It is also described as a national high-tech enterprise and a first-class network enterprise of PetroChina and Sinopec, indicating a manufacturing-oriented industrial supplier rather than a trading-only company.

CertificationsThe supplier reports ISO9001:2015 and ISO14001:2015 certificates, plus other certifications; another company description reports API, UDEM, ISO9001:2008, ISO14001:2004 and OHSAS18001:2007 certifications. These records provide explicit evidence of certification holdings, although the slices do not confirm the current validity or scope of every listed certificate.

After-Sales capabilityWritten procedures and followed records are reported for supplier-service assessment, corrective and preventive actions, and customer complaint handling. However, the supplier reports no overseas warehouse, showroom, agent or branch, and no overseas-service countries, so formal service processes exist but overseas service infrastructure is limited.

R&D capabilityThe supplier reports new products during the past year, ODM services, broad R&D customization, a national science and technology progress award, and more than 20 years of R&D and manufacturing involvement. The absence of an available SDK limits software-development support, but the evidence explicitly supports strong product-oriented innovation capability.

Production capacityThe supplier reports three production lines, 6–10 quality-control staff, annual output of 5,000 downhole motors, and a manufacturing history beginning in 2005. Finished-product inspection is conducted under written instructions that are uniformly followed, supporting established production and quality-control capability.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor and flexible customization, and states that products can be customized to customer requirements. ODM availability and OEM service for well-known brands further support broad customization capability.
