On May 14, 2023, the Zhangye hydrogen energy comprehensive application demonstration project undertaken by China Energy Construction Gezhouba Electromechanical Co., Ltd. successfully tested the high-pressure process pipeline with the highest pressure and difficulty. The monomer debugging stage creates conditions.

The process pipeline of the high-pressure hydrogen filling system undergoing pressure testing this time has a design pressure of 25 MPa and a test pressure of up to 375 kg. In order to ensure the smooth progress of the high-pressure pipeline pressure test, the project department set up a high-pressure pipeline pressure test team to organize all materials such as incoming material inspection, welding records, flaw detection reports, pressure test parameters, etc., and cleaned up the site to establish a pressure test team. In the warning area, the pipeline pressure test work can be completed safely, with high quality and efficiently.

It is understood that Zhangye Hydrogen Energy Comprehensive Application Demonstration Project is located in the circular economy demonstration park of Zhangye Economic and Technological Development Zone, Gansu Province. It is a key project to reduce emissions and promote local economic and social development. Editor / Xie Li
