Katup Globe Dupleks
Struktur mikro katup globe baja tahan karat dupleks terdiri dari campuran fase austenitik dan fase ferit. Oleh karena itu, baja dupleks memiliki sifat baja tahan karat austenitik dan feritik.
Globe valve duplex menggunakan bahan stainless steel yang memiliki ketahanan lebih kuat terhadap korosi dibandingkan dengan grade katup stainless steel yang umum digunakan, yaitu katup 304 dan katup 316. Duplex stainless steel valve banyak digunakan di berbagai industri seperti industri kimia, desalinasi air laut, pembuatan kapal, industri petrokimia, industri minyak dan gas.
