\n CAST IRON PIPES OF CURTAIN CAST IRON<\/span>\n

Ductile Iron Pipes<\/h1>\n <\/div>\n<\/section>\n\n
\n
\n\n
\n

General Description<\/h2>\n

Ductile Iron Pipes (DI Pipes) are one of the most reliable and timeless solutions for water, wastewater, industrial fluid transportation networks and special infrastructure applications.<\/p>\n

They are made of ductile cast iron, a material that combines the high mechanical strength of steel with the resistance of cast iron to corrosion and subsoil stresses.<\/p>\n

The pipes are produced in accordance with international standards EN 545, EN 598 and ISO 2531 and are used in water supply, sewage, irrigation, industrial installations and fire protection networks.<\/p>\n <\/div>\n\n

\n

Key Advantages<\/h2>\n\n

High mechanical strength<\/h3>\n

Malleable cast iron pipes feature:<\/p>\n

    \n
  • Minimum tensile strength \u2265 420 MPa<\/li>\n
  • Yield strength \u2265 300 MPa<\/li>\n
  • Elongation up to 10%<\/li>\n <\/ul>\n

    providing excellent behavior in traffic loads, settlements and seismic actions.<\/p>\n\n

    Long lifespan<\/h3>\n

    The expected lifespan exceeds 100 years when appropriate internal and external protections are applied.<\/p>\n\n
