Berlia Hdpe Pipes Exporters in Delhi Consider the following features of HDPE Pipe: EXCELLENT FLOW CHARACTERISTICS. Because polyethylene is smoother than steel, cast iron, ductile iron, or concrete, a smaller PE pipe can carry an equivalent volumetric flow rate at the same pressure. It has less drag and a lower tendency for turbulence at high flow. Its superior chemical resistance and “non-stick” surface combine to almost eliminate scaling and pitting and preserve the excellent hydraulic characteristics throughout the pipe service life. www.berliapipes.com
