Katup Periksa Duplex<\/h2>\n

WDL Duplex Check Valve<\/strong> provides automatic prevention of reverse flow for process systems that need high strength with resistance to chloride pitting and stress-corrosion cracking. Duplex stainless steel combines austenitic and ferritic phases for chloride service that requires higher strength than 300-series stainless steel.<\/p>\n<\/section>\n

    Catatan Pemilihan<\/h2>\n

    Pilih 2205, 2507, atau jenis baja lainnya berdasarkan kadar klorida, suhu, tekanan, dan tingkat ketahanan terhadap korosi lubang yang dibutuhkan.<\/p>\n

    Pastikan arah pemasangan, laju aliran minimum, tekanan retak, risiko benturan, dan penurunan tekanan yang diperbolehkan.<\/p>\n<\/section>\n

    Pertanyaan yang Sering Diajukan<\/h2>\n

    Why select Duplex Stainless Steel for this check valve?<\/h3>\n

    Baja tahan karat dupleks menggabungkan fase austenitik dan feritik untuk aplikasi yang terpapar klorida yang membutuhkan kekuatan lebih tinggi daripada baja tahan karat seri 300. Kesesuaian akhirnya bergantung pada kondisi proses secara keseluruhan dan komponen katup yang dipilih.<\/p>\n

    Informasi apa saja yang diperlukan untuk proses seleksi?<\/h3>\n

    Sebutkan ukuran, nilai tekanan, komposisi media, konsentrasi, suhu, standar sambungan, metode pengoperasian, dan jumlah yang dibutuhkan.<\/p>\n<\/section>\n
