As a leading EPC contractor and process equipment manufacturer in China, DFC serves industries including petroleum, natural gas, petrochemical, fertilizer, environmental protection, water treatment, pharmaceutical, steel, energy, paper, and food processing. Its products are widely applied in heat exchangers, condensers, air coolers, synthesis towers, reactors, storage tanks, separators, columns, boilers, and other critical industrial systems.
On April 20–21, 2026, a joint inspection team from the American Society of Mechanical Engineers (ASME) conducted a comprehensive renewal audit for DFC's authorized ASME U Stamp certification. Following two days of rigorous, systematic review, the inspection team verified that DFC's quality assurance system operates stably and effectively, with on-site production management and manufacturing capabilities fully meeting the latest ASME Code standards. All inspectors unanimously approved the retention of DFC's ASME certificate and U Stamp, marking the successful completion of the renewal audit with zero non-conformities.
The ASME U Stamp qualification serves as an essential credential for enterprises to export pressure vessels to global markets, acting as a crucial cornerstone for DFC's overseas business layout and international market expansion. Attaching high strategic importance to this renewal audit, DFC mobilized cross-departmental resources to ensure full preparation and smooth cooperation throughout the inspection process.
To guarantee a flawless audit outcome, the renewal preparation work was led by Wendy Zhou, General Manager of DFC, and Juana Jia, Quality Manager. Nine key functional departments, including Procurement, Design, Material Management, Welding, Process Engineering, Inspection, Non-Destructive Testing (NDT), Heat Treatment, and Metrology, coordinated closely to carry out targeted preparatory work and standardized on-site collaboration.
During the audit opening meeting, General Manager Wendy Zhou highlighted the indispensable role of ASME certification in supporting the company's overseas business development and global project cooperation. She required all departments to fully cooperate with the audit team's work, take the renewal inspection as a vital opportunity to benchmark against top-tier international industry standards, and further optimize and upgrade the company's overall quality management system.
Quality Manager Juana Jia further refined the work arrangement by designating special departmental liaisons, clarifying standardized communication workflows, and assigning clear personal and departmental responsibilities for audit cooperation. Meanwhile, the lead auditor of the ASME team elaborated on the audit scope and methodology, stating that the full-dimensional inspection would be implemented through systematic document review and on-site physical verification in strict accordance with official ASME Code provisions.
During the two-day intensive audit, the ASME joint inspection team conducted thorough and detailed verification covering all key modules of DFC's quality management system. The inspection scope comprehensively involved design control procedures, raw material incoming management, standardized welding process implementation, professional non-destructive testing execution, measuring instrument calibration accuracy, in-process product quality inspection, and non-conforming product supervision and control.
The standard audit procedures included an opening kickoff meeting, in-depth review of system documents and technical files, on-site production workshop inspections, on-site witnessing of key welding and NDT operational processes, and professional Q&A exchanges with the company's technical and management personnel.
All involved departments responded efficiently and collaborated closely throughout the audit. For the minor operational deficiencies pointed out by the inspectors, the team completed immediate rectification, supplementary document filing and full on-site closure in a timely manner. Benefiting from the company's mature, sound quality management system and efficient problem-correcting execution capability, DFC successfully completed all audit verification items.
Since obtaining the official ASME qualification authorization, DFC has always adhered to world-class international standards in the whole process of pressure vessel design, development and manufacturing. The successful completion of this zero-defect renewal audit fully confirms that DFC's quality management system continues to meet international normative requirements.
This achievement not only consolidates the company's authoritative international certification credentials, but also provides solid quality support for enhancing core competitiveness in overseas markets and undertaking global power station and industrial boiler projects. In addition, the comprehensive and systematic audit fully verified the compatibility of DFC's full-chain quality assurance system with international industry codes. It also helped the company accurately identify and bridge minor gaps in refined production control, driving sustained optimization of internal management through inspection, assessment and targeted rectification.
As a professional high-quality pressure vessels manufacturer, DFC remains committed to advancing international-grade engineering standards and continuously strengthening its core manufacturing capabilities.
Moving forward, DFC will systematically review and implement all professional optimization suggestions provided by the ASME audit team. The company will further revise and optimize internal system documentation, enhance full-process standardized production control mechanisms, and reinforce employees’ awareness of strict quality and operational compliance. In parallel, DFC will establish a long-term benchmarking system to continuously align daily production and management activities with ASME international standards.
Relying on its sustained and valid ASME certification, DFC will further enhance the global competitiveness of its boiler and pressure vessel products, steadily expand its presence in international markets, and build a stronger quality foundation for the long-term growth of its foreign trade operations and global EPC project cooperation.
