The market demand for PERT II pipes is strong and my country has an urgent need for import substitution.

PERT type II pipe, also known as type II heat-resistant polyethylene pipe, is made of high-density (hdpe) polyethylene and hexene copolymer, using type II imported heat-resistant polyethylene raw materials. PERT is a copolymer of ethylene and α-olefin. It can be divided into PERT I-type pipes and PERT II-type pipes. Since the temperature and pressure resistance of type II pipes is better than that of type I, PERT II pipes have become the main choice for urban secondary heating in recent years. The material of choice for pipe networks.

PERT II pipe is a polyolefin thermoplastic with a transparent white color. Due to its unique molecular branch chain distribution structure, PERT II pipe has the characteristics of high temperature resistance, impact resistance, crack resistance and good strength. It is widely used in industry. It is widely used in civil building hot and cold water pipeline systems, drinking water systems, hot spring insulation pipes, high temperature ground source heat pump systems, urban heating systems, etc. Affected by the geographical environment, the penetration rate of floor heating is higher in the northern region. Therefore, the Northeast and North China are currently the main markets for PERT II pipes. With the acceleration of urbanization, there will be greater development space for the PERT II pipe market in the central and western regions in the future.

PERT II pipes were first commercialized by the American Dow Company. Later, as market demand increased, the number of companies entering the market continued to increase, including Dow Chemical, South Korea’s LG Chem, South Korea’s SK, South Korea’s Dalin, and LyondellBasell. Companies such as Erwin and Total have developed their own PERT II pipe materials, such as Dow Chemical’s Dowlex2388, LyondellBasell’s Hostalen 4731B, Total’s XRT70 and LG SP988, etc.

According to the “2022-2026 China PERT II Pipe Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center It shows that due to limitations of polymerization processes, catalysts and other factors, my country’s polyolefin pipe materials are still mainly general-purpose, and the output of PERT II pipes is low. In 2020, my country’s PERT II pipe consumption will be about 150,000 tons. The current market mainly Rely on imports. In recent years, with the acceleration of modernization and urbanization, the market demand for high-end pipe materials has continued to increase. However, my country’s production capacity of high-end pipe materials is insufficient, and there is an urgent need for domestic replacement of PERT II pipes.

At this stage, domestic companies engaged in the research and production of PERT II pipes mainly include Yangzi Petrochemical, Qilu Petrochemical, Lanzhou Petrochemical, Dushanzi Petrochemical, Tianjin Zhongsha, etc. Domestic PERT II pipes include YEM4705T of Yangzi Petrochemical, QHM32F of Qilu Petrochemical, Daqing Petrochemical’s DQDN3712, Tianjin Zhongsha’s PE100RT, etc. As research continues to deepen, some domestic PERT II pipes have reached the international leading level, and the pace of domestic substitution of PERT II pipes has accelerated.

Industry analysts said that compared to Type I pipes, PERT II pipes have better temperature and pressure resistance, and with market demand Upgrading, PERT II pipe market has great room for development. Restricted by factors such as polymerization processes and catalysts, the output of my country’s PERT II pipe industry is low, and the current market still relies on imports. In future development, relevant companies should accelerate the research and development of advanced catalysts, optimize or develop new polymerization processes, and then gradually realize PERT II pipes. Domestic production of pipes.
