Malleable iron pipe fittings VS Ductile Iron
● Material properties:
Malleable iron pipe fittings: Malleable iron pipe fittings is a pipe-fitting material made from malleable cast iron, which involves heating to plastic temperatures and then cooling to form a structure with greater strength and toughness. Malleable iron pipe fittings is highly deformable and can be cold-worked or forged to obtain the desired shape and properties. 2.
Ductile Iron: Also known as ductile iron or ductile cast iron, ductile iron is a cast iron material whose strength and toughness are improved by adding magnesium alloys during manufacturing. This makes ductile iron more ductile and tensile than traditional gray cast iron while maintaining the excellent fluidity of cast iron.
● Strength and ductility:
Malleable iron pipe fittings: Although Malleable iron pipe fittings has higher strength and toughness, it may be slightly less intense than ductile iron in some high-pressure and high-load environments.
Ductile iron has good toughness and tensile strength and is suitable for water treatment, water supply systems, and other applications involving high pressures and loads.
● Areas of application:
Malleable iron pipe fittings: Suitable for general real estate and construction applications such as air conditioning, heating, ventilation and generally low-pressure piping systems.
Ductile Iron: Ductile iron is commonly used in hydraulic engineering, sewage treatment and industrial piping systems due to its excellent toughness and corrosion resistance.
● Cost considerations:
Malleable iron pipe fittings: Typically, it is a more cost-effective and affordable option for some general-purpose low-pressure systems.
Ductile Iron: Typically relatively expensive, but its performance and longevity provide a better return on investment in applications requiring greater strength and corrosion resistance.
The choice of ductile or malleable iron pipe fittings fittings depends on specific application needs and budgetary considerations. During the manufacturing process, we need to consider the properties of both materials to ensure safe, reliable and economical operation of the piping system.
