Flensa buta digunakan dalam koneksi dua flensa untuk memblokir peralatan pipa, seperti pelat padat, atau pelat baja yang biasa digunakan.Tujuannya adalah pengujian tekanan peralatan pipa, pengujian kebocoran, penyegelan pipa.
Kisaran ukuran pipa produk dari " hingga 96", kisaran grade flange dari 150 # hingga 10.000 #.Produk flensa buta memiliki permukaan liner sambungan lidah dan alur yang cembung atau annular.Produk flensa buta tersedia dalam seri A (MSS SP44) atau B (API 605) dan memenuhi spesifikasi ASME/ANSI B16.5 dan B16.47.
Empat proses produksi utama adalah penempaan, pengecoran, pemotongan dan penggulungan.
Pengecoran flensa
Casting flange, bentuk dan ukuran blanko akurat, volume pemrosesan kecil dan biaya rendah;kelebihannya adalah dapat membuat bentuk yang lebih kompleks.
Flensa palsu
Forging flange umumnya mengandung lebih sedikit karbon daripada casting flange tidak mudah berkarat, penempaan streamline yang baik, organisasi yang padat, sifat mekanik yang lebih baik daripada casting flange.
Potong Flensa
Diameter dalam dan luar dan ketebalan flensa dipotong langsung di pelat tengah, dan kemudian lubang baut dan garis air diproses.Flensa yang dihasilkan dengan cara ini disebut flensa potong, dan diameter maksimum flensa tersebut dibatasi pada lebar pelat.
Flensa digulung
Proses pemotongan strip dari pelat dan kemudian digulung menjadi lingkaran disebut rolling, sebagian besar digunakan dalam produksi beberapa flensa besar.Setelah penggulungan berhasil, pengelasan, kemudian perataan, dan kemudian pengolahan garis air dan lubang baut.
