Inti dari pipa baja besi cor adalah pipa besi ulet, karena pipa besi ulet memiliki esensi besi dan kinerja baja, sehingga disebut ini. Grafit dalam pipa besi ulet ada dalam bentuk bola, dan ukuran grafit umum adalah 6-7 kelas. Dalam hal kualitas, diperlukan bahwa tingkat spheroidisasi pipa besi cor harus dikontrol pada level 1-3, dan laju spheroidisasi harus ≥ 80%. Oleh karena itu, sifat mekanik material itu sendiri telah lebih baik ditingkatkan, dan memiliki esensi besi dan kinerja baja. Setelah anil, struktur metalografi pipa besi ulet adalah ferit plus sejumlah kecil pearlite, dan sifat mekaniknya bagus, sehingga juga disebut pipa besi cor.
Fitur: Ini memiliki esensi besi, kinerja baja, kinerja anti-korosi yang sangat baik, daktilitas yang baik, dan pemasangan yang mudah. Ini terutama digunakan untuk pasokan air dan transmisi gas di perusahaan industri dan pertambangan kota.
