This is just a starting point; more participation from everyone will make things even more lively. Haichuan becomes better with your involvement; we welcome everyone to join in the forum discussions. Be careful with fire as the heat increases in July. -------------------------------------------- At 18:18 on October 26, 2015, the joint venture between Hubei Yihua and Shuanghuan Technology, Xinjiang Yihua, successfully commissioned its 80,000-ton/year melamine production facility, which cost 870 million yuan, and began producing qualified products. This project is the group’s first melamine plant to be completed and put into operation. It utilizes the high-pressure process developed by the Italian company Tecnogas; it represents the first installation based on Tecnogas’ fourth-generation technology, and it is the largest melamine production plant of its kind in the world. The completion and operation of this project have enabled the expansion of Yihua’s industrial chain in Xinjiang, increased the added value of its products, enhanced the competitiveness of the enterprise, and will generate significant economic benefits.
On August 31, 2016, Xinjiang Xinxinxin’s melamine production plant, which utilizes Italy’s Eurotech fourth-generation technology, was successfully put into operation
Xinjiang Xinlianxin’s melamine production facility utilizes advanced fourth-generation European high-pressure non-catalytic technology; it falls under the category of fine chemicals. There are as many as 3,000 key control points in this process, and the level of automation is very high. Neither in terms of facility construction nor production is any existing experience available to guide the work – everything has to be started from scratch. If there is a problem with even a single valve or pipe, the products cannot be produced. The personnel working on the triamine project embody the spirit of \"hard work, dedication to one’s job, and striving to exceed oneself.\" They work and eat on site during the day, and in the training rooms at night to study the principles of the manufacturing process and the installation diagrams; they carefully check each valve and fitting, with their daily rest time being no more than 8 hours. On August 7, 2016, the triamine system began to introduce ammonia; by August 31, the entire process was operational, allowing for the successful production of melamine products. In terms of the process, this was the most difficult drive in the entire history of Heart to Heart. During driving, issues such as severe vibration of the molten salt pump, high pressure difference in the purification system, and internal leakage in the stopcock occurred. Faced with the various challenges that arose during operation, they conducted in-depth analyses and repeated verifications, viewing each difficulty as an opportunity to improve their skills. By taking things step by step, they ensured that the triamine project was brought online on schedule.
On May 10, 2015, the project of Xinjiang Company to produce 60,000 tons per year of melamine produced by the high-pressure method (referred to as melamine) officially commenced construction. During the construction period, Siamine’s staff supervised the work on-site during the day and organized training sessions at night, reporting daily to the workshop about any issues that arose during construction. Each supervisor had a PID diagram and a single-line diagram available; the PID diagram served as the basis for construction, while the single-line diagram acted as a standard for it. While supervising, they compared the dimensions, materials, locations, and pressure levels of each pipeline one by one. In addition, they checked every weld on the pipelines and recorded all details. This thorough and meticulous approach prevented problems such as the use of incorrect materials for the process pipelines, improper piping arrangements, and poor welding quality.
