Guest speeches
Chen Xinwei, President of the China Chemical Fiber Industry Association, said in his speech that the healthy development of the polyester industry chain plays a decisive role in the operation and development of the textile and chemical fiber industry. In recent years, leading polyester companies have actively improved the layout of the entire industrial chain from crude oil-PX-PTA-polyester-textile, which has further strengthened the integration and scale advantages of my country’s polyester industry, reduced the risk of price fluctuations of chemical fiber raw materials, and is conducive to The sustained and stable development of my country’s polyester industry chain. With the rapid development of the industry, PTA and polyester staple fiber, as important components of the polyester industry chain, have also led more industries such as equipment and financial futures to pay attention to the development of the polyester industry chain. A high-quality development conference for the PTA and polyester staple fiber industry is held here to conduct exchanges around hot issues such as industry operations, new technology applications, green manufacturing, futures and options that are of common concern to the industry, and to accurately grasp the latest trends in the industry and promote new technologies and new processes. It is of great significance to develop and transform financial instruments to better serve the real economy and further promote high-quality development of the industry.
Zhu Xiaofeng, deputy general manager of the sales department of Zhejiang Jiuli Special Materials Technology Co., Ltd. and director of Huzhou Baoti Jiuli Titanium Welded Pipe Technology Co., Ltd., said in his speech that Jiuli Special Materials, Baoti Jiuli and related units are PTA and other Participants in the localization of production equipment and materials. In many domestic PTA projects, Jiuli Special Materials has served as the main supplier, providing stainless steel and nickel alloy pipes, heat exchange tubes and other products. In terms of special materials used in PTA devices, in addition to providing a large number of titanium welded pipes for PTA surface coolers, Baoti Jiuli also introduced YishengNew Materials Company in 2020 The domestic production of PTA oxidation condenser titanium welded pipes provides titanium welded pipes. Jiuli Special Materials and Baoti Jiuli hope to make more contributions to the localization of PTA devices in the future.
Cooperation and joint construction base licensing
Zhejiang Jiuli Special Materials Technology Co., Ltd. is a national high-tech enterprise specializing in the production of industrial stainless steel and special alloy pipes and fittings. Its subsidiary Huzhou Baoti Jiuli Titanium Welded Pipe Technology Co., Ltd. has built the country’s leading positive pressure cleaning plant for corrosion-resistant and high-precision titanium welded pipes for PTA, and has 8 fully automatic titanium and titanium alloy welded pipe production lines, including form welding The unit, sizing, straightening, heat treatment, cutting and finishing, underwater airtightness, non-destructive testing and packaging and storage equipment meet the process requirements of INVISTA and have unique advantages.
Based on the demand for corrosion-resistant high-precision special alloy pipes in the chemical fiber upstream PTA industry and the advantages of Jiuli Special Materials in the production technology and product quality of special alloy pipes, the China Chemical Fiber Association and Jiuli Special Materials have cooperated to build the “PTA Used “Corrosion-resistant high-precision special alloy pipe R&D and production base” actively provides high-quality and reliable basic materials for the construction of my country’s PTA industry and contributes to the localization of PTA device materials. At the meeting, the awarding ceremony of the “Corrosion-resistant High-Precision Special Alloy Pipe R&D and Production Base for PTA” was held.

Forum report
Fu Wenjing, deputy secretary-general of the China Chemical Fiber Industry Association, and Zhang Lingqing, secretary-general of the Polyester and Polyester Staple Fiber Professional Committee, chaired the morning and afternoon forums respectively.
Industry operating status, futures market and industry trend outlook
New requirements and suggestions for high-quality green development of the PTA industry under the “dual carbon” goal
The “dual carbon” goal in the new era puts forward higher requirements for the green and low-carbon development of the PTA industry. Dr. Yu Juan, deputy director and associate researcher of the Textile and High-Quality Development Research Office of the Consumer Goods Industry Research Institute of the CCID Research Institute of the Ministry of Industry and Information Technology (China Electronic Information Industry Development Research Institute), sorted out the policy system and roadmap for green and low-carbon development at home and abroad, and analyzed The energy consumption and carbon emissions of my country’s chemical fiber industry were analyzed. At present, the transition from relative carbon reduction to absolute carbon reduction, from high-carbon economy to low-carbon economy, from energy conservation and emission reduction to pollution reduction and carbon reduction, from dual control of energy consumption to dual control of carbon emissions has evolved. It has become a new trend and new requirement for my country’s industry and PTA industry to achieve green and low-carbon development under the “double carbon” goal. She gave a detailed explanation.�Achieving the best use of materials; the second is energy integration, more optimized thermal energy integration, efficient recovery and utilization of oxidation reaction heat, refining preheating and crystallization systems, etc., the PTA device has changed from a traditional net input of electric energy to a net input of electric energy. output, greatly reducing the comprehensive energy consumption of PTA production; the third is system integration, the integration of PTA and PET, the integration of PTA and high-pressure steam boilers, etc.
Introduction to localization capabilities of key components of PTA equipment
Sun Wenqiang, assistant to the dean of the research institute of Zhejiang Jiuli Special Materials Technology Co., Ltd., introduced its organizational structure, talent construction, scientific research equipment, standard patents, etc., and demonstrated its The nationalization of key components of PTA equipment provides a support system and R&D and production strength. Among them, Jiuli Steel Laboratory is a CNAS-certified laboratory, Moore Joint Laboratory, and TÜV Rheinmetall Materials Testing Collaborative Laboratory. The first phase of the steel laboratory covers a total area of more than 2,600 square meters. It has four testing rooms: metallographic and microscopic analysis room, mechanical property testing room, chemical analysis testing room and corrosion performance testing room. It has 200 large and medium-sized equipment with advanced performance. It has multiple sets and has the Thermo-calc&Dictra software specially developed by the Royal Swedish Institute of Technology for thermodynamic and kinetic calculations. These software and hardware can record material data and achieve full traceability through the QMS system; they can provide one-stop supporting services to shorten the supply cycle; and combine test data and manufacturing processes to continuously improve product stability and reliability.
