Reply rewards! ---------------------------------------------- The past ten years have been an era of great development for China's chemical industry. The emergence of many new processes, new products, and new equipment has also led to a great development in my country's chemical equipment, which has also promoted the rapid development of the petrochemical industry. Here we have collected and sorted out some of the achievements and breakthroughs made by my country's equipment companies in the large-scale and localization of equipment. Welcome everyone to share, discuss, and exchange, cheer for Made in China, and cheer for chemical equipment! ===================== In the 1 million tons/year reforming and transformation project of Zhuhai Changlian Petrochemical Co., Ltd., Longhui Company stood out among many competitors by virtue of its compact structural size, excellent operating parameters, and short manufacturing period. It won the bid for the design and manufacturing of the reforming feed coiled heat exchanger, and successfully signed the contract in October 2016. Since the start of the project, the leaders of Longhui Company have attached great importance to it, and relevant departments have fully cooperated. The design R&D center and the design company have continuously optimized the design plan. The equipment manufacturing branch has gone all out to rationally coordinate and overcome all unfavorable factors such as tight construction schedules, heavy tasks, and cold weather. They have given up holidays, divided into four groups to work 24 hours a day after the materials were received, and people were off the machine. It took 85 days to complete the project with quality and quantity, creating the "Longhui Speed" in the industry. The equipment has a diameter of 2.8 meters, a length of 12.6 meters, a total weight of more than 100 tons, and a complex internal structure. The shell is made of hydrogen-resistant and heat-resistant steel 14Cr1MoR(H). Welding is difficult. In addition, due to the cold winter, welding cracks will occur if you are not careful. For this reason, the construction personnel specially designed and manufactured flame heating facilities and timely post-weld heat treatment to ensure the welding quality. In the core technology pipe winding process, strict quality control procedures are implemented to ensure the quality of each process, ensuring the overall quality and making the Longhui brand famous.
