Inspeksi Produk
1. Pemeriksaan Komposisi Kimia
Chemical composition inspection is carried out on the Hastelloy B2 raw material and, jika diperlukan, on the finished flange to verify compliance with UNS N10665 persyaratan. Key elements such as nickel, molibdenum, kromium, iron and carbon are checked against ASTM limits. This process helps confirm corrosion-resistant performance and prevents off-grade alloy substitution in critical project supply.
2. Pengujian Sifat Mekanik
Mechanical properties testing verifies that forged Hastelloy B2 material achieves the specified tensile strength, kekuatan hasil, elongation and hardness after heat treatment. Test samples are reviewed according to relevant ASTM requirements or project specifications. These tests confirm the flange has sufficient structural integrity for pressure-retaining service, welded assemblies and demanding nozzle or vessel connections.
3. Inspeksi Dimensi
Pemeriksaan dimensi mencakup diameter luar, membosankan, panjang hub, long neck profile, ketebalan, lingkaran baut, bolt hole diameter and facing geometry. Raised face or RTJ groove dimensions are checked carefully to ensure gasket compatibility and correct assembly. This inspection is especially important for long weld neck flanges used on vessels and equipment where transition dimensions must match design drawings precisely.
4. Pengujian PMI dan Pengujian Hidrostatis
PMI testing is performed using portable analyzers to confirm the alloy identity of Hastelloy B2 before shipment. When specified, hydrostatic or assembly pressure testing is arranged to verify pressure integrity in finished systems or special fabricated components. SASA FLANGE dapat menyediakan EN 10204 3.1 sertifikat, material test reports, inspection records and traceable heat numbers with the delivered flanges.
