Wanlong's Special Equipment Manufacturing License (TS Certification) has been successfully updated and officially approved. This update introduces the new Class A2 pressure piping valve manufacturing certification, building upon the existing Class A1 and Class B licenses. This milestone marks Wanlong's achievement of comprehensive qualification coverage across the A1/A2/B class spectrum.
Within the previous licensing framework, Wanlong possessed the capability to manufacture Class A1 valves (metal valves with nominal pressure ≥10MPa and nominal diameter ≥300mm) and Class B valves (other metal valves with nominal pressure >4.0MPa and nominal diameter ≥50mm). The newly acquired Class A2 certification officially enables Wanlong to enter the cryogenic valve manufacturing sector. These valves are primarily used in extreme service conditions such as LNG facilities, low-temperature petrochemical processes, and the aerospace industry, demanding the highest standards in material selection, structural design, and manufacturing techniques.
Securing the Class A2 certification is a direct result of Wanlong's sustained investment in R&D and equipment upgrades. The company has established a dedicated technical team meeting Class A2 requirements, allocated significant resources to optimize production facilities and equipment, and implemented a robust quality assurance system supported by necessary inspection and testing equipment to fully guarantee product quality.
This significant achievement not only reflects the high recognition from national safety supervision departments for Wanlong's technical prowess and production capabilities but also signifies a major step forward in the high-end valve manufacturing arena. The expansion from A1/B to the full A1/A2/B portfolio represents a substantial leap in the company's comprehensive technical strength and market coverage capabilities.
This certification upgrade holds strategic importance for Wanlong's market expansion, empowering the company to serve a wider range of industrial sectors, particularly within the high-end energy and chemical markets. Obtaining the full A1/A2/B certification suite is a crucial milestone in Wanlong's development journey, but we will not rest here. The company remains committed to its philosophy of "Customer First, Quality Wins, Technology Innovation, Market Expansion," and will continuously advance technological R&D and quality enhancement.
Looking ahead, Wanlong will further deepen R&D and application of valves for special service conditions, expanding its product portfolio for even more demanding environments. Simultaneously, the company will continue to increase investment in digital and intelligent manufacturing, adopting advanced production and quality management methods to consistently improve product performance and quality stability.
