Product Introduction
Ductile Iron Pipe C40 ,C30,C25 is made of ductile cast iron, and it is commonly used for potable water transmission and distribution. It is characterized by the spheroidal or nodular nature of the graphite within the iron. It has excellent anti-corrosion performance, good ductility and easy installation, and this pipe has high bright surface without bump, no black spot, no cracks and flat weld seams.
Features
Ductile Iron Pipe C40 ,C30,C25 increases the mechanical properties of cast iron, increases plasticity and toughness to obtain a higher strength than carbon steel. The comprehensive performance of ductile iron is close to that of steel, and it can be used to cast some parts with complex force and high strength and toughness requirements.
