Inspeksi Produk
1. Pemeriksaan Komposisi Kimia
Chemical composition inspection is performed to confirm that the duplex stainless steel used for the flange meets ASTM A182 F51 requirements. Key alloying elements such as chromium, nikel, molybdenum and nitrogen are verified against the specified range to ensure corrosion resistance, mechanical strength and compliance with the mill test certificate.
2. Pengujian Sifat Mekanik
Mechanical testing is used to verify tensile strength, kekuatan hasil, elongation and hardness of the forged flange material after heat treatment. These tests confirm the material has achieved the required duplex structure and strength level for pressure service. Test results are reviewed against applicable standards and included in the quality documentation package.
3. Inspeksi Dimensi
Pemeriksaan dimensi mencakup diameter luar, diameter dalam, ketebalan flensa, lingkaran baut, bolt hole size and quantity, and facing details. Untuk flensa sambungan pangkuan, fit-up with the mating stub end is also checked to ensure free rotation and proper assembly. All dimensions are verified according to ASME, EN, DIN, JIS, GB atau gambar pelanggan.
4. Pengujian PMI dan Pengujian Hidrostatis
PMI testing is conducted using portable analyzers to confirm duplex 2205 material identity and prevent grade mix-up in critical projects. While flanges themselves are normally not hydrostatically tested as individual components, hydrostatic pressure testing can be arranged as part of assembled spool or project requirements. EN 10204 3.1 certificate and traceable inspection records are provided.
