en.Wedoany.com Reported - The review draft of the CECS "Technical Specification for Water Hammer Protection in Water Supply Engineering," led by Southern Valve, passed expert review. On May 30, 2026, the review meeting was held at the Southern Valve Dongfang Shuigu Laboratory, hosted by the Building and Municipal Engineering Product Application Branch, with over 30 representatives from the main and participating compiling units attending both online and offline.
Tang Yajun, Director of the China Association for Engineering Construction Standardization; Gu Taichang, Secretary-General; Yang Jinchun, Deputy Secretary-General; and Yu Chaoxing, Commissioner, attended the meeting. The review expert group was led by Ma Xiaolei (Chief Engineer and Professor-level Senior Engineer at China Northwest Municipal Engineering Design and Research Institute Co., Ltd.) as the chair, with Luo Dingyuan (Professor-level Senior Engineer at China IPPR International Engineering Co., Ltd.) as the vice chair. Members included Liu Jing from China Building Standard Design and Research Institute Co., Ltd., Zhang Zhili from CCTEG Beijing Huayu Engineering Co., Ltd., Du Junmin from the Henan South-to-North Water Diversion Operation Support Center, Xu Jiajiong from Shanghai Municipal Engineering Design Institute (Group) Co., Ltd., Professor Zhou Ling from Hohai University, and Professor Hou Qingzhi from Tianjin University, all holding senior engineer titles. The expert group, together with all members of the standard compilation team, participated in the review.
During the meeting, the compilation team reported on the background, technical framework, core content, experimental verification, and research findings of the specification. The expert group reviewed the draft article by article, providing revision opinions and improvement suggestions on key aspects such as scope of application, technical requirements, design specifications, construction acceptance, and operation and maintenance, forming clear review conclusions.
The attending experts visited the Southern Valve Dongfang Shuigu Laboratory on-site, inspecting R&D and testing facilities, full-process testing capabilities, innovative achievements in water hammer protection technology, and engineering application cases. The expert group recognized Southern Valve's core technology R&D, product iteration, and engineering practice capabilities in the field of water hammer protection, and affirmed its responsibility in driving industry technological progress.
The review expert group concluded that the specification's compilation was well-researched, drawing on advanced domestic and international standards and engineering practice experience, with standardized procedures, complete documentation, and compliance with review requirements. The specification systematically defines technical requirements for water hammer protection in water supply engineering, providing guidance for engineering design, construction, acceptance, and operation management. Its content is scientifically sound, highly operable, and coordinated with current relevant standards, innovatively proposing an overall technical solution for water hammer protection. The expert group unanimously agreed that the specification passed the review.
Next, the lead compiling unit will revise and improve the specification based on the review opinions, complete the standard approval process with high quality, and promote the standardization, normalization, and high-quality development of water hammer protection in water supply engineering.
