In addition, because plastic pipes are mainly used in infrastructure construction areas such as communications, construction, gas supply, water supply, and drainage, the long project implementation cycle has led to a long period of settlement and large -scale liquidity. The pipeline production capacity ratio is unreasonable.

For small and medium -sized enterprises, the cost of production can be used by centralized procurement. In order to compete for the market, some companies use price -driven strategies, especially some small enterprises to dump their low prices with inferior products.

Plastic granulator: Driven by relevant national policies, in recent years, the development of the Industrial Twin shaft shredder machine domestic plastic pipe industry has shown a strong growth trend and has become the main force of the domestic plastic processing industry. my country's technical level in the plastic pipe industry is weaker than developed countries, and there is still a gap between scientific research forces and funding. strength.

The price war has intensified and is in a vicious price competition. Due to the blind investment and excess capacity of low -end products, its malignant effects have begun to appear. In addition to the original gas pipes and heating pipes, the application of polyethylene pipe market for alien forces has also begun to enter the urban and rural drainage pipe and pipeline market in recent years.

Domestic plastic pipe manufacturers have entered the era of micro -profit. At present, the pipeline and pipeline production capacity ratio is about 15: 1, which is far from the normal application ratio of 8: 1, and there are few types of pipelines.
