What are the future development trends of flame - retardant bellows?

China began to introduce plastic corrugated pipe production lines in the mid-1980s. Currently, among the plastic corrugated pipes that have been developed and applied in China, 80% are HDPE corrugated pipes. 

HDPE double-wall corrugated pipes will play a significant role in the field of buried drainage due to their excellent performance-price ratio, and they have a broad market prospect. The application of HDPE double-wall corrugated pipes in China first started to be promoted in the field of building drainage. In particular, the advantages of these pipes in the field of buried drainage are gradually being recognized, and they have already been widely applied in some regions. 

In recent years, the usage of HDPE double-wall corrugated pipes has increased rapidly. Judging from the current level of pipe irrigation in China, agricultural drainage and irrigation is a huge market for HDPE double-wall corrugated pipes. With the continuous development of the application and construction technology of HDPE double-wall corrugated pipes, the demand for these pipes in these fields will gradually increase. 

On the other hand, as an important part of corrugated pipes, flame-retardant corrugated pipes have undergone more than 80 years of development and research. Especially in the past 40 years, due to the demand of the polymer industry for flame-retardant corrugated pipes, they have developed into a large series of products. The development trend of the global flame-retardant corrugated pipe industry is moving towards non-toxicity, harmlessness, high efficiency, specialization, and compounding.
