Zhongtong HDPE TUBO Sistema Fornitore Professionale
Tubi in ghisa sferoidale, crafted from ductile iron material, are renowned for their core attributes: exceptional strength, remarkable corrosion resistance, and straightforward installation. The process involves adding a nodulizing agent during casting, transforming the iron’s graphite into spherical shapes, significantly enhancing the mechanical properties of the material.
Tubo in ghisa sferoidale
The primary advantages of ductile iron pipes encompass:
Tubo in ghisa sferoidale
Alta resistenza: Ductile iron boasts significantly greater strength than gray cast iron, con una resistenza alla trazione superiore a 420 Mpa, rendering it suitable for high-pressure applications.
Eccellente resistenza alla corrosione: Ductile iron pipes surpass steel counterparts in corrosion resistance, offering a service life of over 50 anni e resistenza a vari ambienti corrosivi.
Facilità di installazione: Ductile iron pipes feature flexible joints, streamlining installation, reducing construction time, and resulting in cost savings.
Cost-Effectiveness: While the initial cost of ductile iron pipes may be higher than gray cast iron pipes, their extended service life and minimal maintenance requirements translate into superior long-term cost-effectiveness.
