International Endorsement | Henan Letone Ultra-High Voltage Equipment Co., Ltd. Successfully Obtains

On March 31, Henan Letone Ultra-High Voltage Equipment Co., Ltd. (hereinafter referred to as Letone Ultra-High Voltage Equipment), a wholly-owned subsidiary of Letone Technology, officially passed the on-site inspection by the American Society of Mechanical Engineers (ASME) joint inspection team and successfully obtained the ASME BPVC Section VIII Division 3 (U3) manufacturing license and steel stamp authorization. With this, Letone Ultra-High Voltage Equipment becomes the ninth company in China to obtain this certification, and the third company in China with isostatic pressure as its core business to obtain ASME U3 steel stamp authorization. This milestone breakthrough not only signifies that Letone Ultra-High Voltage Equipment's design, manufacturing, and full-process quality control capabilities in ultra-high voltage vessels have reached international standards, officially obtaining the authoritative "passport" to enter the global high-end equipment market, but also injects strong momentum into the high-quality development and internationalization layout of Henan Letone Equipment.

ASME certification is a globally recognized benchmark for quality and safety in the industrial equipment field, and an essential qualification for entering international markets such as North America, the Middle East, and Southeast Asia. The ASME U3 certification obtained this time represents the most stringent technical threshold and control requirements within the ASME pressure vessel standard system, specifically tailored for pressure vessels operating under ultra-high pressure conditions. Compared to the industry's standard U certificate, the U3 qualification imposes almost demanding requirements on a company's safety factor selection, fatigue analysis capabilities, material performance verification, and stress classification and control under extreme conditions. This certification is far more than just an ordinary certificate; it is a globally authoritative endorsement of the company's ultra-high pressure "extreme manufacturing capabilities," signifying that Letone Ultra-High Pressure Equipment has officially acquired the core strength to compete with international ultra-high pressure equipment companies.

This joint inspection was organized and implemented by an ASME officially authorized audit team, with authorized testing institutions participating in and supervising the entire process. The audit team adopted an audit model of "system audit + document review + on-site witnessing," conducting a comprehensive and thorough inspection of the company's quality management system, core aspects including R&D capabilities, process control, ultrasonic testing, and material traceability. Through comprehensive on-site verification, Letone Ultra-High Voltage Equipment's quality management system was found to be operating effectively and in accordance with regulations, its entire process record was complete and traceable, and its manufacturing and testing capabilities fully met all the stringent requirements of the ASME U3 standard. Ultimately, with its outstanding comprehensive capabilities, Letone successfully passed the inspection and obtained U3 certification.

The successful acquisition of ASME U3 certification marks a significant leap forward for Letone Ultra-High Voltage Equipment, enabling a dual upgrade in both its technological capabilities and management system. Standing at this new starting point, Letone Ultra-High Voltage Equipment will leverage this ASME U3 certification as an opportunity to continuously deepen its expertise in the core ultra-high voltage equipment sector, thoroughly integrating international standards into every aspect of product development and manufacturing. Relying on the cutting-edge R&D platform of the "One Institute, Four Research Institutes" Ultra-High Voltage Fluid Innovation Research Institute, Letone Ultra-High Voltage Equipment will actively expand into the global high-end equipment market. With superior product quality and comprehensive service capabilities, it will showcase to the world the systematic strength of China's independent R&D in high-end equipment and the power of its national brands, striving to write a new chapter in the high-quality development of Chinese manufacturing.
