What is the current status of PVC pipes?

Since the 1980s, China has introduced thousands of different types of PVC pipe extrusion production lines, and large pipe manufacturers such as Dalian Shide, Zhejiang Yonggao, and Shanghai Tomson have emerged. At present, there are more than 600 manufacturers of uninterruptible power supply (rigid PVC) pipes and fittings in China, with a total production capacity of more than 1.1 million tons per year. There are more than 30 manufacturers with a production scale of more than 10,000 tons/year, and more than 60 manufacturers with a scale of 5,000-10,000 tons/year. The production equipment of uninterruptible power supply pipelines and pipe fittings has basically realized localization. In China, polyvinyl chloride pipes were developed earlier than polyethylene pipes and polyvinyl chloride pipes. There are many varieties, excellent performance and wide use, and they occupy an important position in the market. As of the end of 1999, there were about 2,000 plastic pipe production lines in China, of which about 15% were imported equipment. In 1999, the production capacity of various plastic pipes in China exceeded 1.65 million tons per year, and the actual output exceeded 5 million tons, of which polyvinyl chloride pipes accounted for more than 50%. In recent years, among them, the rise of medium PVC pipelines in the national construction production lines is more than 60% of the American construction pipelines, including construction pipelines and 60% of the American construction pipelines.

PVC pipe

At present, the application of plastic pipes in my country has made great progress not only in quantity, but also in varieties and specifications. For example, UPVC pipes have reached more than 90% of the construction drainage applications in some cities. In recent years, most UPVC pipe companies have achieved very good benefits. During the "Tenth Five-Year Plan" period, the popularization and application of plastic pipes were mainly UPVC and PE plastic pipes, and other new types of plastic pipes were vigorously developed. By 2005, in the nationwide new construction, reconstruction and expansion projects, 50% of building drainage pipes will be made of plastic pipes, 20% of urban drainage pipes will be made of plastic pipes, and 60% of building water supply, hot water supply and heating pipes will be made of plastic pipes. 50% of urban water supply pipes (below Dn400) use plastic pipes, 60% of township water supply pipes use plastic pipes, 50% of urban gas pipes (medium and low pressure pipes) use plastic pipes, and 80% of construction wire sheathing pipes. 80% use plastic pipes. It is estimated that plastic pipes of more than 20.5 million tons, of which plastic pipes of more than 5 million tons, 60% of the water supply pipes in villages and towns, 60% of plastic pipes, 50% of urban gas pipes (medium and low pressure pipes), 50% of plastic pipes), 50% Plastic pipes, 50% construction plastic pipes, 50% construction plastic pipes, 80% construction wire sheathing pipes, 80% construction plastic pipes, and 80% construction plastic pipes.

At present, there is not a single county in China that has full-pipe irrigation, and most areas of the country lack a basic understanding of irrigation. Therefore, increasing the publicity and promotion of PVC irrigation in rural areas has great potential.
