In industrial fluid control systems, the reliability, durability, and adaptability of valves directly determine production efficiency, safety levels, and operating costs. Traditional metal valves are difficult to cope with media containing particles, strong corrosion, and high wear. However, ceramic knife gate valves, with their advantages in ceramic materials, scientific structural design, full field adaptability, and economic efficiency, have broken through the limitations of traditional valve

The emergence and widespread use of metal corrugated tubes, corrugated expansion joints, and corrugated tube heat exchangers have made corrugated tubes an important application field for connecting, compensating, and heat exchange components. They have broken through the scope of instrument elastic components and are mainly used in pipeline systems in industries such as power, metallurgy, petrochemicals, and central heating. They serve as flexible connections and thermal compensation components,

According to the material of corrugated pipes, they can be divided into two categories: plastic corrugated pipes and metal corrugated pipes.
