GB-standard spiral steel pipes - ASTM A252

The structural integrity of large-diameter hot-dip galvanized spiral steel pipes is a key factor contributing to their widespread adoption in industrial ventilation. The expansive diameter of these pipes allows for the efficient conveyance of a significantly larger volume of air, a critical requirement in vast industrial setups like automotive manufacturing plants, steel mills, and large - scale logistics centers. In automotive factories, for example, during the painting and assembly processes, a multitude of volatile organic compounds (VOCs) and dust particles are generated. The large-diameter pipes can rapidly draw in and exhaust these pollutants, maintaining a clean and safe working environment. The unique spiral welding technique employed in production plays a pivotal role in enhancing structural strength. This method results in a homogenous and robust structure, distributing mechanical stress uniformly throughout the pipe wall. As a result, the pipes can endure the fluctuating pressures and constant mechanical vibrations inherent in ventilation systems without succumbing to deformation or failure. In power plants, where ventilation systems operate continuously under high - temperature and high-humidity conditions, these pipes remain resilient, ensuring the stable operation of the plant's critical systems.
