Certifications and Quality Management for Drilling Rigs

Company-level quality management

Founded in 1941, HuBei SJ Petroleum Machinery Co.Ltd is a drilling rig manufacturer in China and an oilfield drilling equipment supplier, manufacturing drilling and workover equipment with onshore and offshore product lines. The company profile references ISO 9001, HSE, and API Q1 quality management, with a product set covering drilling equipment, cementing equipment, workover equipment, fracturing equipment, coiled tubing units, snubbing units, offshore equipment, and high-pressure fluid control products.

Product-level API referenced practice

Rig structural components are manufactured to API 4F and API 7K referenced design and testing practice, with certificates and design documentation available for buyer review during technical clarification. In practice this means derricks, masts, and substructures follow API 4F structural design practice, while drawworks and hoisting assemblies follow API 7K equipment practice, with documentation matched to the specific rig model you are evaluating.

Buyers shortlisting equipment across the full product range should request documentation per major assembly rather than relying on a single factory statement. The API 4F / API 7K certification guide explains what each standard covers and how to verify it.

This package is part of the OEM and export support process, which also covers voltage and drive configuration, climate packages, transport and site planning, spare parts, and optional commissioning. Certificates and design documentation are available for buyer review during technical clarification before any purchase commitment.
