The anti-static and flame-retardant components of polyethylene pipes used underground in coal mines are uniformly distributed throughout the pipe body, so the anti-static and flame-retardant performance indicators will not be affected by long-term use. The anti-static and flame-retardant properties meet national standards and are suitable for flammable and explosive environments underground.

Plastic well casings are lightweight, corrosion-resistant, durable, and inexpensive. In foreign countries, especially developed countries, over 80% of water wells use plastic casings. The future trend in the water well field is to use new materials for well construction to solve corrosion and scaling problems, especially corrosion problems in high-salt areas. PVC-U plastic pipes have the advantages of low cost, no corrosion, and long service life, so they have broad application prospects and market. Does not pollute water quality High burst strength, good seismic performance Inexpensive pipe materials, low well construction cost
