2023 API Audit and Follow-Up Review Minutes

Summary of the 2023 API audit and follow-up review, including cause analysis, corrective actions, preventive actions, observations, and nonconformity control.

This document summarizes the 2023 API audit and follow-up review. The minutes record the issues observed during the on-site review, the departments involved, and the corrective and preventive actions required for quality-system improvement.

Cause Analysis

High-pressure flow control components, including valves, tees, crosses, threaded connections, and other pressure-containing connections, were newly developed products. During development, some personnel did not fully understand the API Spec 6A and API quality-system requirements for measurement, inspection, and documentation control.

Corrective Actions

The corrective plan included training on API Spec 6A, API Spec Q1, national metrology regulations, and related API requirements; assessment of trained personnel; revision of periodic calibration plans; recalibration of pressure transmitters approaching their due date; and evaluation of metrology personnel competence.

Preventive Actions

Preventive actions included continued training on API requirements, competency assessment for relevant personnel, and reinforcement of document control, calibration control, supplier control, design review, and nonconforming-product control.

Review Observations

The follow-up review identified improvement items related to pressure gauge accuracy, documented procedures, quality objectives, special-process records, design inputs, witness load testing, NDE numbering, design-change evaluation, contract review, approved supplier evaluation, outsourced special processes, measuring-tool control, statistical analysis, equipment maintenance, personnel responsibilities, API monogram control, internal audit planning, and pressure-test monitoring.

Nonconformity Control

For each nonconformity, the responsible department should define a corrective-action plan, implement the action within the required period, verify effectiveness, and retain complete objective evidence. Issues found by sampling do not mean other departments or documents are free from similar problems; all departments should conduct self-checks based on the review findings.

The purpose of the review is not only to close individual findings, but also to improve the stability, traceability, and effectiveness of the API quality management system.
