Application of Songjiang Metal Bellows in the Fujian Zhangzhou Damin Food Coffee Line Project

Founded in April 1995, Fujian Zhangzhou Damin Food (Zhangzhou) Co., Ltd. is a professional enterprise engaged in the deep processing of natural plant products. As the world’s largest producer of tea extracts and the third-largest producer of natural plant extracts globally, Damin Food has obtained multiple international certifications such as ISO9001, HACCP, and ISO14001, and serves as a supplier to numerous multinational food and beverage companies in Europe and the United States.In the coffee production line project of Damin Food, there existed challenges related to pipe expansion and contraction under high-temperature and high-pressure conditions. Failure to effectively manage these changes could result in damage and failure of the pipeline system, thus affecting the overall operational efficiency and safety of the production line.To address the aforementioned challenges, Shanghai Songjiang Vibration Absorber Group Co., Ltd. provided high-quality metal bellows and single rubber expansion joints for the project. These metal bellows possess the following characteristics:

High Elasticity and Flexibility: Metal bellows effectively absorb and compensate for pipe expansion and contraction caused by temperature changes, preventing stress concentration in the pipeline.
High Temperature and Pressure Resistance: Manufactured using high-quality stainless steel materials, metal bellows can work stably for a long time under high-temperature and high-pressure environments.
Easy Installation: Modular design facilitates convenient installation and maintenance, reducing downtime of the production line.

Since the installation of metal bellows, the pipeline system of Damin Food’s coffee production line has operated more stably, significantly reducing failures and maintenance costs caused by thermal expansion and contraction. Specific effects include:

Improved Production Efficiency: Reduction in unplanned downtime of the production line, enhancing overall production efficiency.
Extended Equipment Lifespan: Effectively alleviated stress on the pipeline system, extending the lifespan of pipes and related equipment.
Enhanced Safety: Application of metal bellows has reduced potential safety hazards under high-temperature and high-pressure environments, ensuring the safe operation of the factory.
