PLASTECH PLUS INC. offers PE pipes ranging from ½" to 63" in diameter. Because of their unique physical characteristics, PE pipe products are widely used where other materials cannot be. For instance, HDPE Water Pressure Pipes can be connected by a process called butt fusion, where the ends of the pipes are heated and joined together. This can be used in trenchless applications where digging is difficult or impossible. Black HDPE and Yellow MDPE gas pipes are used for natural gas transmission, where a zero leak rate is crucial.
