Ürün Denetimi
1. Kimyasal Bileşim Denetimi
Chemical composition inspection is carried out on the Hastelloy B2 raw material and, gerektiğinde, on the finished flange to verify compliance with UNS N10665 gereksinimler. Key elements such as nickel, molibden, krom, 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. Mekanik Özellikler Testi
Mechanical properties testing verifies that forged Hastelloy B2 material achieves the specified tensile strength, akma dayanımı, 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. Boyutsal Muayene
Boyutsal inceleme dış çapı kapsar, delik, göbek uzunluğu, long neck profile, kalınlık, cıvata dairesi, 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. PMI Testi ve Hidrostatik Test
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.
