Axial flow compressor for ethylene refrigeration i

The "axial flow check valve for ethylene refrigeration compressor" of dieper large ethylene plant ended the long-term monopoly history of foreign countries. On May 8, 2020, the nps30/class300 axial flow check valve for compressor of large ethylene plant developed by Zigong new dieper Valve Co., Ltd. successfully passed the localization appraisal organized by China Machinery Industry Federation and China General Machinery Industry Association. After rigorous examination, inquiry and demonstration, the expert group finally

on May 8, 2020, the axial-flow check valves such as NPs 30/class300 for compressor developed by Zigong xindiper Valve Co., Ltd. for large-scale ethylene plant, whose stress is proportional to strain, successfully passed the localization appraisal organized by China Machinery Industry Federation and China General Machinery Industry Association. After rigorous examination, inquiry and demonstration, the final appraisal conclusion of the expert group is: "the large ethylene device" axial flow check valve for ethylene refrigeration compressor "developed by Zigong xindiper Valve Co., Ltd. has independent intellectual property rights, and the product fills the domestic gap. The main technical parameters and performance indicators have reached the advanced level of similar international products, of which the sealing performance is superior to similar foreign products." After the completion of identification, these four valves will be delivered to the owner, thus ending the history that such check valves have been monopolized by foreign manufacturers

the expert committee of the appraisal meeting has a strong lineup, led by Han Jianyu, the chief equipment expert of Sinopec, and has gathered top experts in ethylene, compressors and valves in China. By China Petroleum and Chemical Corporation, Hefei General Machinery Research Institute, Sinopec Engineering Construction Co., Ltd., Sinopec Luoyang (Guangzhou) Engineering Co., Ltd., Hualu Engineering Technology Co., Ltd., Sinopec Ningbo Engineering Co., Ltd., Shenyang Blower Group Co., Ltd., School of petroleum and chemical engineering, Lanzhou University of technology, China Huanqiu contracting & Engineering Co., Ltd 11 highly respected ethylene, compressor and valve experts from Wison Engineering (China) Co., Ltd. and Sinopec Tianjin Petrochemical Company

the experts of the appraisal meeting watched the production site of Xindi Pell workshop through video or on-site inspection, witnessed the factory test of products, listened to the new product development work report, and reviewed the technical summary report The third-party performance test report was checked (the appearance inspection of the in mold labeling package of the national pump and valve product quality supervision and inspection center of Hefei General Testing Institute, the anti-static test of the valve, the strength test of the shell, the air tight seal test, the fatigue life test, the low-temperature seal test and the air tight seal test after restoring the normal temperature.) And other relevant identification materials, as well as through the formulation of technical documents for the development of key varieties, there were full questions and discussions. Finally, the experts of the appraisal meeting fully affirmed and spoke highly of the research and development work done by xindiper, and unanimously agreed to pass the appraisal

at the appraisal meeting, xindipel company said that based on the inspiration of long-term research and development, the energetic team has achieved the relevant functions of the electronic universal testing machine, and has accumulated experience in successfully delivering thousands of axial-flow check valves. It is fully confident that under the guidance of China Machinery Association and China Communications Association, it will continue the legend of the research, development and application of axial-flow check valves
