The seas and rivers are more lively and exciting with your participation. I wish everyone a happy new year and a safe and healthy family.

Welcome to discuss.---------------------------------------------------------------- In March 2022, the 11th Institute of Aerospace (Beijing) signed a contract for a 60-inch cracking gas valve for the Tianjin Nangang ethylene project, setting a world record for cracking gas valve caliber. The cracking gas valve produced by the 11th Aerospace Institute is a key piece of equipment on the ethylene cracking furnace. The German brand has always occupied a dominant position. Its largest application diameter at home and abroad is 56 inches, with more than 100 48-inch units sold. The maximum caliber of the 11th Institute (Beijing) is 48 inches, and there are only 3 units. They have always been suppressed in terms of quantity and caliber. The No. 9 cracking furnace of Tianjin Nangang Ethylene Project adopts the world's first 200,000-ton single-furnace process. The supporting cracking gas valve is planned to use a 60-inch double-gate gate valve. There is no reference plan in the world. The weight of a single valve will reach 42 tons. Its manufacturing difficulty, installation difficulty, and action reliability are far higher than existing products. It is a huge challenge for both the German brand and the 11th Institute (Beijing). Aiming for the 60-inch will set a world record for cracking valve caliber, and at the same time occupy the commanding heights of the product's technical level and manufacturing capabilities. The 11 Institute (Beijing) cracked gas valve products used excellent 48-inch application performance, leading innovative design capabilities, and complete and efficient manufacturing and testing guarantees to dispel the concerns of the design institute and owners, confirm the original design intention of the 60-inch cracked gas valve, and win an opportunity for the institute to compete equally on the same stage. In the end, the 11th Institute (Beijing) relied on innovative valve technology solutions, long-term low-cost use experience, and fast and timely support services to successfully win the 60-inch cracking valve, set a world record for cracking valve diameter, and completed a gorgeous overtaking on a curve. The project broke the German brand's monopoly on large-diameter cracked valves, dismantled its carefully constructed last line of defense, and achieved double transcendence in technology and caliber. It provides support for the domestic production and internationalization of all domestic ethylene process package equipment. The project also received full support from the Sinopec headquarters. The Sinopec Major Equipment Localization Office identified it as a localization project project, laying a solid foundation for subsequent innovation achievement declaration and market promotion.
