PE Pipe

PE pipe is a thermoplastic piping product made primarily from polyethylene resin through extrusion molding, and is categorized into HDPE, MDPE, and LDPE based on density. These pipes feature good chemical resistance (resistant to various acids, alkalis, and salts), outstanding flexibility (elongation at break over 350%), strong low-temperature impact resistance (remains flexible even at -60 °C), and good hygiene performance (compliant with drinking water standards). PE pipes use heat fusion to create seamless, integral joints. Specifications are denoted by outer diameter × wall thickness (e.g., DN200×11.9 mm SDR17), and working pressure can range from 0.4 to 1.6 MPa. They are widely used in municipal water supply and drainage (especially buried pipelines), gas distribution (yellow and black pipes), agricultural irrigation (e.g., drip systems), industrial fluid transport, and subsea pipelines. With a service life of over 50 years, good resistance to ground settlement, and convenient construction (can be coiled for transport), PE pipes have become a preferred material in modern piping infrastructure projects.
