Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Progress in Chemical Engineering Equipment】Continuous updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** A major breakthrough has been achieved in the domestic production of acetylene compressors. May 5, 2025 – Recently, the acetylene compressor units developed by Shanghai Qiyao Screw Machinery Co., Ltd. (referred to as “Qiyao Screw”) were successfully put into operation in the Sichuan Yongying New Materials project from the very first attempt! The 2 units of 630 acetylene compressors and 2 units of 816 in series with 408 pyrolysis gas compressors delivered this time not only break the long-standing market monopoly held by imported equipment, but also signify a significant technological breakthrough in China’s field of high-end compressor manufacturing. Breakthroughs in technical research: As the \"core equipment\" in the chemical industry chain, pyrolysis gas compressors play key roles in pressurizing and transporting gases as well as in maintaining process stability; their performance has a direct impact on the safety and energy efficiency of acetylene production facilities. Facing the technical challenges posed by the flammability and explosiveness of acetylene as a medium, as well as its tendency to decompose under high pressure, Qi Yao Screw has, through years of research and development, successfully overcome key challenges in material selection, sealing technology, and explosion-proof design. It has established a comprehensive technical system that covers the entire process from design and development to production, manufacturing, and installation and commissioning. The domestic production of third-generation screw compressors has gone through a \"three-step progression\": starting out as spare units for imported machines, progressing to operating alongside imported equipment, and now reaching the point where they completely replace imported machines as the main processing units. Qi Yao Screw has accomplished this full localization process. The successful implementation and operation of this project not only indicate that Qiyao Screw has mastered core technologies that enable independent control in the field of acetylene compressors, but it also signals a comprehensive improvement in the quality of services provided by Qiyao Screw. Qi Yao Screws is committed to providing customers with a more considerate, professional, and efficient service experience, meeting their needs comprehensively from pre-sales consultation to after-sales maintenance. As an important basic raw material for the production of new chemical materials such as PVC and BDO, the equipment upgrading in the acetylene industry is of great significance for achieving the \"dual carbon\" goals. Qi Yao Screws will continue to deepen its commitment to the concept of \"full-life-cycle service.\" By leveraging a digital operation and maintenance platform, it will establish a device health management system, offering customers value-added services such as remote diagnosis and energy efficiency optimization, thereby driving the industry toward smarter and more sustainable practices. In the future, Qi Yao Screw will continue to drive industry development through technological innovation, providing global customers with more efficient and safer compressor solutions and helping to write a new chapter in the localization of high-end equipment.
