The first domestic set of fully surfacing-welded Hastelloy welding materials (E309L+C276) used for a PTA hydrogenation reactor: In March 2021, the hydrogenation reactor for the integrated petrochemical project undertaken by Lanzhou Heavy Equipment for Jiangsu Jiatong Energy Co., Ltd.—which involves an annual production capacity of 5 million tons of PTA, 2.4 million tons of new functional fibers, 10,000 tons of benzoic acid, and 5,600 tons of acetaldehyde—was successfully completed. Additionally, the PGA reactors for Shenhua Yulin Energy and Chemical Co., Ltd.’s 50,000-ton/year polyglycolic acid project have also been completed at both the Qingdao and Lanzhou bases. The Jiangsu Jiatong Energy PTA project is equipped with 2 hydrogenation reactors, each with a diameter of 5.6 meters and a weight of 570 tons. These reactors use special materials, with their inner walls fully cladded with Hastelloy welding materials (E309L+C276); such reactors are the first of their kind in China. The company analyzed the challenges in manufacturing, optimized production methods, and advanced technological innovation; as a result, it developed a surfacing method using Hastelloy C276, ensuring both the thickness and quality of the surfacing layer. The successful completion of this product marks a new breakthrough in the manufacturing process and technical capabilities for hydrogenation reactors in LANXI Heavy Equipment’s PTA plants.
It’s tough in the scorching summer heat! Keep up with heat prevention and cooling! Clarify the key tasks! Safety analysis must not be neglected! ----------------------------------------------The past decade has been a period of rapid development in China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! ------------------------------------------------------ 【Ministry of Emergency Management’s Special Inspection 2022】Summary Edition – Feel free to participate in discussions and self-inspections! ! ! ! https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=3418729 (Source: Huahai Chuanliu – Haichuan Network) Summary post for the 【Major Chemical Equipment in China】 series; being updated. https://bbs.hcbbs.com/thread-3366481-1-1.html (Source: Huahai Chuanliu – Haichuan Network)
