This is just an initial contribution; more participation will make the discussion even more lively. Haichuan becomes even better with your involvement; we welcome everyone to engage more in discussions on this forum. It’s hot in July, so be careful to prevent fires. --------------------------------------------- The domestic production project for NPS14 Class2500 high-pressure hydrogenation axial flow check valves: Over the past *** years, Xindi Per has been dedicated to the continuous research and development of special valves. Its core product, the axial flow check valve, has seen numerous key technological advancements. These valves have enabled substitution for imported products in critical applications such as long-distance pipelines, LNG projects, and large-scale ethylene plants, breaking the long-term monopoly held by European and American brands. The main technical specifications of these valves reach advanced levels comparable to those of international counterparts, with improvements in areas such as flow control, sealing performance, and service life over foreign products. On July 13, 2023, the Materials and Equipment Department of Sinopec, Sinopec Zhenhai Refining & Chemical Co., Ltd., and Sinopec Guangzhou Engineering Co., Ltd. held a kick-off meeting for the project aimed at developing domestic alternatives to axial flow check valves used in high-pressure hydrogenation processes in Zigong, Sichuan. High-pressure hydrogenation axial flow check valve technology requires a high level of expertise and presents significant manufacturing challenges, which have not yet been overcome. Given the respective technical advantages and characteristics of Xindi Per and China National Nuclear Corporation, Sinopec initiated the project, with Zhenhai Refining & Chemical Co., Ltd. and Sinopec Guangzhou Engineering Company organizing the two manufacturing firms to work together on this task.
