Recently, BAOYI Group's full range of safety valve products successfully passed the rigorous review by the American Society of Mechanical Engineers (ASME) and was officially awarded the ASME UV Stamp certification. This marks that the Group's design, manufacturing, and testing of safety valves fully comply with the requirements of the ASME BPVC Section VIII pressure vessel code, successfully securing a place among the world's premium compliant safety valve product lines. It grants critical market access for entering international project markets in Europe, the Americas, and beyond, including oil and gas, chemical processing, air separation, and hydrogen energy sectors.

Authoritative Seal, Proven Excellence

The ASME UV certification is one of the most authoritative and influential technical certifications for pressure relief devices globally, and a widely adopted critical access standard for international pressure vessel, energy equipment, and process industry projects. This certification not only focuses on product performance but also imposes systematic requirements on a company's design capabilities, manufacturing standards, and quality management systems, serving as a vital benchmark for assessing the international compliance and overall strength of safety valve products.

Rigorous Audit, Exceptional Performance

This audit covered five core dimensions: design calculation verification, raw material traceability, critical component mechanical testing, actual gas flow capacity measurement, and full-process quality system review. On-site sampling was conducted by the NBBI (National Board of Boiler and Pressure Vessel Inspectors) authority, subjecting products to full-operating-condition performance testing. Four key parameters—set pressure accuracy, blowdown performance, rated capacity, and seat leakage—all passed with results exceeding ASME mandatory standards.

Technology Foundation, Systematic Implementation

Earning this ASME UV certification represents a significant achievement from BAOYI Group's long-term commitment to overpressure protection technology and continuous product upgrades for safety valves, marking an important milestone in the company's international development strategy.

Addressing diverse medium conditions in the oil & gas and chemical equipment sectors, the company has persistently pursued technological breakthroughs in key areas, including spring structure optimization, low-temperature/corrosion-resistant material selection, flow path simulation, and precision sealing processes. This has established a systematic technical framework covering product design, manufacturing, and performance validation, consistently enhancing product safety, reliability, and adaptability to various operating conditions.

Through continuous optimization and upgrades, core parameters such as set pressure deviation, blowdown performance, rated capacity, and leakage at ambient temperature now comprehensively exceed both Chinese national standards and ASME limit requirements. These products are capable of meeting overpressure protection demands across complex operating conditions in petrochemicals, fine chemicals, new energy, and other fields.

Benchmarked to High Standards, Advancing Toward Quality

Looking ahead, BAOYI Group will continue to maintain the ASME annual surveillance inspection system, driving R&D innovation and manufacturing upgrades guided by the highest international standards. We are committed to continuously enhancing product core competitiveness, providing safer, more reliable, and more efficient total overpressure protection solutions for global industrial projects. BAOYI Group—taking certification as a stepping stone, and safety as our promise—stands with global customers to build a stronger industrial safety defense line.
