HDPE double-wall corrugated pipes have a wide range of applications and my country’s industry concentration needs to be improved

HDPE double-wall corrugated pipe, referred to as PE corrugated pipe, refers to a pipe with a double-wall corrugated structure made of high-density polyethylene as raw material. Compared with other structural pipes such as concrete pipes and metal pipes, HDPE double-wall corrugated pipes have the advantages of low production cost, lightweight, long service life, good toughness, and high pressure resistance. They are widely used in highways, municipal drainage, chemical plants, mining areas, It is widely used in farmland, power system and other scenarios.

High-density polyethylene (HDPE) is the raw material of HDPE double-wall corrugated pipes. High-density polyethylene has the advantages of good chemical stability, good low-temperature toughness, good electrical insulation, and acid and alkali resistance. It is widely used in pipes, membrane materials, building materials, fiber products and other fields. In the early stages of industry development, my country’s high-density polyethylene market as a whole was in short supply, and products were highly dependent on imports. In recent years, with technological advancement, my country’s high-density polyethylene production capacity has further expanded and output will increase, which provides favorable conditions for the development of the HDPE double-wall corrugated pipe industry.

As a new type of plastic pipe, HDPE double-wall corrugated pipe is widely used in many fields. In the agricultural field, HDPE double-walled corrugated pipes can be used for drainage, irrigation and water delivery, etc.; in the municipal field, they can be used in drainage pipe networks and power grid construction; in the construction field, HDPE double-walled corrugated pipes can be used as underground drainage pipes and ventilation pipes. , sewage pipes, etc.; in the chemical industry, HDPE double-wall corrugated pipes have corrosion resistance, acid and alkali resistance, etc., and can be used for chemical wastewater discharge.

According to the “2023-2028 China HDPE Double-wall Corrugated Pipe Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that in recent years, in order to promote rapid economic development, the country has attached great importance to people’s livelihood issues such as the renovation of old communities and rural domestic sewage treatment, and has introduced many solutions to the problems. Against this background, the application demand for HDPE double-wall corrugated pipes in my country continues to grow, and its output has also increased, reaching nearly 500,000 tons in 2022.

There are many HDPE double-wall corrugated pipe manufacturers in my country, and the market competition is fierce. Weixing New Materials, Gudi Technology, Xiongsu Technology, Jinshi Pipe Industry, Xicheng Environmental Protection, Jinbo Pipe Industry, Jinpeng Pipe Industry, Dongxing Pipe Industry, Diyang Plastic Industry, Ruiqi Plastic, etc. are the HDPE double-wall corrugated pipes in my country. major producers. Ruiqi Plastic focuses on the production of HDPE large-diameter double-wall corrugated pipes. Its annual production capacity reaches nearly 160,000 tons, ranking first in my country. However, at present, my country’s HDPE double-wall corrugated pipe industry has low entry barriers. The market is dominated by small and medium-sized enterprises, and product quality is uneven. This is the main challenge facing the development of the industry.

Industry analysts said that HDPE double-wall corrugated pipes have excellent performance and are widely used. They are expected to become a substitute for traditional concrete pipes and metal pipes in the future. product. However, at present, my country’s HDPE double-wall corrugated pipe industry has low concentration, the market lacks leading companies, and product quality is uneven. In the future, with the continuous improvement of industry standards and the improvement of the technical level of local enterprises, my country’s HDPE double-wall corrugated pipe industry will gradually develop in the direction of high quality.
