Inspeksi Produk
1. Pemeriksaan Komposisi Kimia
Chemical composition inspection verifies that the forged nickel alloy used for the flange conforms to the specified grade such as UNS N06600 atau N06625. Raw material certificates are checked and laboratory analysis is performed when required to confirm alloying elements including nickel, kromium, molybdenum and other controlled elements before production release.
2. Pengujian Sifat Mekanik
Mechanical testing is carried out according to the applicable material specification and project requirement. Tes yang umum mencakup kekuatan tarik, kekuatan hasil, elongation and hardness to confirm the forged flange material has adequate strength and ductility for high temperature and pressure service. Results are recorded and linked to the heat number for traceability.
3. Inspeksi Dimensi
Pemeriksaan dimensi mencakup diameter luar, ukuran lubang, dimensi hub, ketebalan, lingkaran baut, bolt hole quantity and hole diameter. Sealing face type and finish, including RF height or RTJ groove dimensions, are checked against ASME, EN, DIN, JIS, GB or approved customer drawings to ensure proper fit-up and sealing performance during installation.
4. Pengujian PMI dan Pengujian Hidrostatis
