Happy May Day 2024! Safety first **********************【Ten Years of Rapid Development in Chemical Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Forum Website) ***************** On April 29, 2024, the two acrylonitrile reactors, which are key equipment for Wanhua Chemical’s (Penglai) specialized engineering plastics production project and were manufactured by Zhanghuaji (Suzhou) Heavy Equipment Co., Ltd., were successfully delivered. It is reported that the acrylonitrile reactor delivered this time is the core unit for producing acrylonitrile, one of the three key monomers used in ABS plastics. It has a diameter of nearly 10 meters, a height of over 30 meters, and a net weight of around 500 tons. This equipment is large in size, complex in structure, and requires high precision. In particular, the two core conversion furnaces have a diameter of 3.6 meters and a total weight of 220 tons; they are to be delivered within 4.5 months, presenting a tight deadline and heavy workload. To ensure timely delivery, Zhanghua Machinery broke down complex processes such as \"original drawing creation, procurement of key materials, and preparation of technical drawings\" into smaller tasks and carried them out simultaneously, thereby completing the preparation of the main materials within one month ； By optimizing production processes, 24/7 continuous manufacturing is achieved; precise control ensures a first-time inspection pass rate of up to 99.9%, resulting in almost zero rework. In the end, relying on its extensive experience in manufacturing super-large reactors, its advanced hardware capabilities, and its advantageous location at the port, Zhanghua Ji carefully planned the project, organized production meticulously, and ensured strict quality control, thereby delivering the equipment three months ahead of schedule and fulfilling its commitment to \"addressing customers’ urgent needs and meeting their requirements.\"
