【Ten Years of Rapid Development in Chemical Processing Equipment】Hot-state Testing of Special Valves for Polyester Melt 650-2022

Thread Content

Witness the ten-year rapid development of chemical processing equipment; praise the prosperity and strength of modern China. Replies will be rewarded – discussions are welcome. ------------------------------------------- In the production processes of industries such as fiber optics and polyester, as well as biodegradable materials, melt filters are among the essential key devices. It is mainly used to remove agglomerated and gelatinous particles formed during the reaction process, coking products, as well as solid impurity particles introduced into the system during the preparation of raw materials and reagents. For nearly three decades, Xi’an Pump and Valve Factory Co., Ltd. has been dedicated to the production of valves and equipment specifically designed for the polyester melt industry. Valves used in this sector account for over 90% of all polyester valves used in China. Additionally, Xi’an Pump and Valve Factory Co., Ltd. holds the approval necessary for designing and manufacturing pressure vessels of Class A2. Whether it is in terms of industry technical knowledge, polyester production process technology, or capacity, processing quality, and manufacturing precision, all these factors provide a solid foundation for the design and manufacture of polyester melt filters. Due to the harsh operating conditions of polyester reactors, in addition to strengthening the regular inspections and tests during reactor manufacturing, thermal simulation tests are also required to ensure the reliable operation of the equipment over extended periods in its operational environment. Thanks to the successful completion of this hot-state system test, Xi’an Pump and Valve Factory Co., Ltd. has become one of the few manufacturers in the industry capable of carrying out both manufacturing and hot-state testing. It not only significantly improves the technical level of the enterprise but also enhances its reputation in the field of polyester fibers, thereby boosting the company’s market competitiveness in this industry.
