Detil Produk
A zirconium blind flange is a non-bored flange designed to seal the end of a piping line, vessel opening or equipment nozzle where future inspection, maintenance or system expansion may be required. Because zirconium offers outstanding resistance to many organic acids, alkalis and chloride-bearing media, these blind flanges are widely selected for chemical processing, acetic acid production, tanaman farmasi, offshore systems and specialty corrosive services.
SASA FLANGE supplies forged and machined zirconium blind flanges in standard and custom dimensions with strict process control. Available documentation and inspection include chemical analysis, pengujian mekanis, pemeriksaan dimensi, pengujian PMI, EN 10204 3.1 sertifikat dan ketertelusuran nomor panas penuh. Pengeboran khusus, special facing and non-standard thicknesses can be produced to suit project drawings and service requirements.

Inspeksi Produk
1. Pemeriksaan Komposisi Kimia
Chemical composition inspection is performed to verify the zirconium grade conforms to ASTM requirements for UNS R60702 or R60705. Spectrometric analysis and review of mill data confirm control of Fe, Kr, Hf, oksigen, nitrogen and hydrogen limits. This ensures the flange material has the required corrosion resistance and suitability for aggressive chemical process environments.
2. Pengujian Sifat Mekanik
Mechanical testing confirms the flange forging meets specified tensile strength, kekuatan hasil, persyaratan perpanjangan dan kekerasan. Test coupons are evaluated according to the applicable material standard and heat treatment condition. These checks help ensure the blind flange has adequate strength for bolted closure service while retaining the ductility needed for safe installation and operation.
3. Inspeksi Dimensi
Pemeriksaan dimensi mencakup diameter luar, ketebalan, lingkaran baut, diameter lubang baut, dimensi menghadap, raised face height and overall flatness. The sealing surface finish is checked to match the gasket requirement of RF, FF or RTJ design. This inspection is essential for proper alignment, leak-tight assembly and interchangeability with mating flanges made to international standards.
4. Pengujian PMI dan Pengujian Hidrostatis
PMI testing is carried out to confirm positive identification of zirconium alloy grade and to avoid mixed-material risk during production and packing. When specified, hydrostatic or assembly pressure verification is performed at system level or as project requirement. SASA FLANGE menyediakan EN 10204 3.1 sertifikat, inspection reports and heat number traceability for complete documentation.
