With the warm spring breeze, peach blossoms in the northern regions are blooming in succession, and all living things are bursting with vitality. The pioneering and flourishing technological innovations of Zhongke Weier are ushering in a new chapter!
On the morning of April 14, 2026, the appointment ceremony for the Chief Technical Expert of Zhongke Weier was successfully held at the company’s headquarters in Shenyang. Attending the ceremony were Company Chairwoman Zheng Liqun, General Manager Tang Zhiwen, Executive Vice President Hu Lihong, other senior executives, company experts, and heads of various centers. In addition, selected employee representatives participated both online and offline. During the event, Yan Weili, a seasoned expert in refining and petrochemical corrosion protection, was officially appointed as Zhongke Weier’s Chief Technical Expert.
During the appointment ceremony, General Manager Tang Zhiwen presented Expert Yan Weili with her letter of appointment, while employee representatives presented her with flowers. All colleagues then welcomed Expert Yan’s official joining of Zhongke Weier with warm applause.
To begin, Expert Yan Weili delivered her acceptance speech, expressing profound honor at being appointed Chief Technical Expert at Zhongke Weier and deep gratitude for the trust placed in her by company leadership and the warm welcome extended by her colleagues. She then reflected on her decades-long career at Zhenhai Refining & Chemical—thirty-two years dedicated to frontline corrosion protection, safeguarding equipment safety through her expertise and setting industry standards through her unwavering commitment. Upon retirement, she received heartfelt recognition and fond farewell messages from both leadership and colleagues, bringing a perfect close to the first half of her professional journey.
Joining Zhongke Weier at this new stage of her career is a precious opportunity to continue shining and making meaningful contributions in a field she is passionate about. She has always believed that the true value of technology lies in its application, in passing on knowledge and expertise, and in empowering business growth. It is precisely this original aspiration that led her to resolutely choose to join the Zhongke Weier team. She solemnly pledged that, once in her role, she will devote all her technical expertise and professional insights to advancing the company’s key technological challenges, enhancing its business performance, and solving its most pressing problems. With a rigorous, pragmatic, and relentlessly perfectionist approach, she will do everything possible to support the effective implementation of corporate decisions and the company’s long-term development, thereby strengthening the organization’s technological foundation. Finally, she expressed her heartfelt wishes for Zhongke Weier to thrive and achieve even greater success.
Subsequently, Zheng Liqun, Chairperson of the Company, delivered a welcoming address, extending a warm welcome to expert Yan Weili on her joining the team. She recalled that she first met Expert Yan in 1999 when the two collaborated on a science-and-technology project commissioned by Sinopec Headquarters, and over the past 27 years their shared commitment to corrosion protection has forged a deep and lasting bond. Yet what we have long affectionately called “Engineer Yan” has now risen to become a leading industry expert; therefore, we are truly honored to have extended this invitation and to have it accepted.
Ms. Zheng summarized the company’s significant milestones: “At the very beginning of our establishment, we were fortunate to appoint Academician Cao Chunan as our Chief Advisor. Academician Cao guided us in pursuing a path of self-reliance and independent innovation, and emphasized the importance of steadfastly supporting our researchers as they embark on the entrepreneurial journey—this has always been the cornerstone of our existence. Since then, we have boldly taken the lead and never given up. In mid-2014, we were further privileged to recruit Mr. Dong Shaoping, formerly head of the Mechanical Department at Sinopec’s Zhenhai Refining & Chemical Company, as our Chief Expert. Under his strategic guidance on corrosion prevention and operational reliability for petrochemical facilities, we have engaged in pragmatic planning and deep, sustained efforts, laying a solid foundation for our corrosion-control and asset-integrity business, achieving a strong start and ensuring its continuous, steady growth.” Ms. Zheng then expressed her heartfelt gratitude to Mr. Dong Shaoping and the entire team of experts for their outstanding contributions over the years.
She pointed out that the company is currently undertaking nearly 30 on-site corrosion maintenance projects, with a team of more than 130 corrosion and protection technicians. However, there is still room for improvement in the team’s technical capabilities, and the responsibility of ensuring safe production for our customers remains a formidable challenge. The appointment of Expert Yan to lead the expert team will provide professional guidance to all of the company’s technical personnel, strengthen our capacity for technological innovation and problem-solving, and enable us to swiftly and effectively address corrosion issues in our customers’ operations at a high standard—actions that are of great significance in enhancing the core value of our corrosion protection business. Expert Yan’s arrival will undoubtedly further solidify the company’s technological foundation over the next decade, foster the development of more specialized corrosion professionals, and help the company reach new heights. Finally, she extended her best wishes to Expert Yan, hoping that he will enjoy a happy and fulfilling experience within the Zhongke Weier family and that his work will proceed smoothly!
In his concluding remarks, General Manager Tang Zhiwen stated that Expert Yan Weili has devoted many years to the field of corrosion prevention in refining and petrochemical processes, possessing a solid theoretical foundation and extensive practical experience. Her addition to the company represents a pivotal step in addressing our technological gaps and enhancing our core competitiveness. The company will provide full support and resource assurance to the expert, and we urge all technical personnel to cherish this learning opportunity, proactively draw on Expert Yan’s professional ethos, engineering mindset, and expertise in assessing and diagnosing corrosion issues, thereby elevating the company’s technical capabilities to a new level and collectively contributing to the advancement of corrosion control.
The appointment of this chief expert injects strong momentum into the company’s technological innovation, product iteration, and high-quality development. Moving forward, Zhongke Weier will, under the expert guidance of Mr. Yan, continue to deepen technological innovation and talent development, delivering more professional and efficient services to ensure the safe and reliable operation of petrochemical facilities while enhancing their performance and efficiency.
