Update on Drawing Review and First-Article Inspection

We have updated our execution rules for drawing review and first-article inspection to shorten turnaround and control the features that affect sealing and assembly. The review now checks: material confirmation (e.g., CF8M, A105, 316L, 17-4PH), heat treatment or hardfacing requirements, pressure rating and flange interfaces, gasket-surface roughness targets, hole/bore concentricity and keyway sizing, ISO 5211 hole patterns for brackets/adapters, thread and chamfer standards, and coating or surface-protection thickness ranges. Areas prone to interpretation differences are flagged with notes; providing STEP/IGES helps remove ambiguity.

First-article inspection focuses on datum planes, fit tolerances, and sealing faces. A dimensional report and EN 10204 3.1 certificate are provided as standard. Upon request and with prior booking, we can add 3.2 witnessing, PMI, dye-penetrant or magnetic-particle testing, and other special checks. For standard parts and small batches with complete documentation, we target a 24-hour turnaround for a feasible lead time and quotation. Projects requiring special tools, jigs, or materials will receive a clear preparation lead time and key milestones after review.

To improve efficiency, please include media temperature and corrosivity, target leakage/seal class, whether actuator or adjacent-component fit checks are needed, and any special packaging/labeling requirements when submitting drawings. These updates apply across common valve parts for chemical, energy, and water service. We will continue to refine the procedures based on project reviews to maintain consistency and traceability in delivery.
