Ten years of rapid development in chemical engineering equipment – praising the prosperity and strength of modern China. This is just a starting point; more participation will make things even more lively. Haichuan becomes even better with you here; we welcome everyone to join in the forum discussions and exchanges. ********************************************* Xian, March 10 – According to reports by reporter Zhang Yichen, the 60-inch large valve for pyrolysis gas, developed by Institute 11 of the China Aerospace Science and Technology Corporation (hereinafter referred to as CASIC Institute 11), has been completed. This product is a key component of the world’s first ethylene cracking furnace with a 200,000-ton single-furnace process, breaking international monopolies and achieving advancements both in technology and capacity. It is reported that during the product manufacturing process, the team innovatively adopted topological optimization to manufacture the valve body, which increased its load-bearing capacity to 1.5 times that of the original valves without increasing weight; this reduced the likelihood of product jamming. Additionally, the product’s structure was upgraded to achieve lighter weights ； By using a labyrinthine fairing, the erosion rate is reduced by 90%, extending the product’s service life. Currently, one 60-inch pyrolysis gas valve can achieve the same processing capacity as two 48-inch pyrolysis gas valves, significantly reducing costs. The Sixth Academy of Aerospace Science and Technology stated that the successful development of this product will provide strong support for the localization and internationalization of all equipment in the ethylene process package, and it will also assist in the initiation of further localization projects, the submission of innovation achievements, and market promotion.
A valve of 42 tons... it’s terrifying just to think about it. Give a thumbs up to the technical staff
The true era of great national powers and powerful technologies has begun; every bit of progress is hard-won.
