Shenyang Xinyulin Petroleum Machinery Co., Ltd. officially launched the 2026‑2027 API annual audit work with the kick‑off meeting. Professional API auditors attended the meeting and carried out on‑site inspections of our production workshop, processing equipment, quality control system and finished product testing area.
During the meeting, the management team introduced our whole manufacturing process, quality management procedures and continuous improvement measures for API standard compliance. The audit team conducted detailed communication on document control, production traceability, material inspection and product quality assurance requirements.

Subsequently, the auditors visited the production site, carefully inspected machining workshops, assembly lines and testing laboratories. They fully reviewed our implementation status of API specifications in actual production, and gave targeted guidance on process optimization and standardized management.
API certification is a core international qualification for petroleum equipment manufacturers. This annual audit is an important inspection of our quality system. We always strictly follow API standards in the design and manufacturing of choke manifold control panels and other petroleum machinery products.

Through this audit activity, we will further standardize production workflows, strengthen full‑process quality control, and consistently provide reliable, API‑compliant petroleum machinery products for global customers. We will keep improving our manufacturing capability and quality management level to meet the diversified demands of oil & gas projects worldwide.
