The heat treatment of the joint where the cylinder head and the tube sheet meet in the high-pressure methamine condenser, one of the four key devices for urea production manufactured by Zhengyuan Tower Equipment, was successful on the first attempt. Author/Source: Yangmei Zhengyuan Group; Date: 2020-10-22; Views: 15. The production of this high-pressure methamine condenser is nearing completion. The heat treatment of the joint between the cylinder head and the tube sheet is a critical factor affecting the quality of the equipment, as heating the material used in urea production is inevitable during heat treatment, and excessive temperatures can cause irreversible damage to the corrosion resistance of this material. Although there is prior experience in manufacturing such devices, it still represents a significant challenge for technicians who have not been involved in previous projects. These technicians sought guidance from senior engineers and experienced workers, studied the relevant standards carefully, and with the help of the senior engineers, determined the appropriate temperature and duration for heat treatment, as well as the temperature required to maintain the corrosion-resistant layer. Through the collaborative efforts of all departments, tasks such as installing electric heating elements, setting up thermocouples, and applying insulation material were completed successfully. This ensured that the heat treatment was successful from the first attempt. The successful heat treatment of the joint at the high-cold seal head in just one attempt secured valuable time for the timely renewal of the tower’s certification. With the maturity of Zhengyuan Tower Equipment’s urea production technology, the monopoly held by a few companies over the four key components used in urea production in China has been broken. This has laid a solid foundation for expanding the range of products manufactured by Zhengyuan Tower Equipment, improving its production capabilities, creating new sources of economic growth, and achieving further success. Under the guidance of party committees at all levels, Zhengyuan Tower Equipment will continue to innovate and produce high-quality products, thereby providing new impetus for the development of the non-standard equipment manufacturing industry in North China and across the country.
