(China, Guangzhou – April/October 2025) – The 138th China Import and Export Fair (hereinafter referred to as the "Canton Fair") is set to grandly open at the Poly World Trade Center Expo in Guangzhou. As a leading enterprise in China's pressure vessel manufacturing sector, Xinglong Pressure Vessel Manufacturing Co., Ltd. (hereinafter referred to as "Xinglong Company") is fully prepared to make a significant appearance. The company will debut its latest range of high-end, high-efficiency, and high-safety pressure vessel products and solutions, demonstrating the exceptional achievements and innovative vitality of "Intelligent Manufacturing in China" within the industrial equipment field.

　　In industrial production, food preservation, medical experiments, and other fields, nitrogen is used as a protective gas, and the stability of its terminal pressure directly affects product quality and process safety—insufficient pressure during welding can lead to inadequate protection, pressure fluctuations in food packaging can cause nitrogen leakage, and laboratory analysis requires constant pressure to ensure testing accuracy. However, traditional nitrogen tanks often face the challenge of “high initial pressure but rapid terminal pressure decay” during long-term use: as nitrogen is consumed inside the tank, pressure gradually decreases. When it drops to the equipment's operating pressure, frequent replacement or refilling is required, which not only affects production efficiency but may also lead to quality issues due to unstable pressure. Xinglong's self-pressurizing nitrogen tank addresses this challenge through technological innovation.
