Inspeksi Produk
1. Pemeriksaan Komposisi Kimia
Chemical composition inspection is carried out to verify that chromium, nikel, molibdenum, nitrogen dan elemen paduan lainnya memenuhi persyaratan tingkat dupleks atau super dupleks yang ditentukan. Raw material certificates are reviewed and laboratory analysis is performed when required to confirm compliance with ASTM, EN or customer specifications before production release.
2. Pengujian Sifat Mekanik
Pengujian mekanis memverifikasi kekuatan tarik, kekuatan hasil, elongation and hardness in accordance with the applicable material standard. For duplex and super duplex flanges, these tests help confirm the required strength level and proper heat treatment condition. Test results are recorded against each heat number and included in the quality documentation package when specified.
3. Inspeksi Dimensi
Inspeksi dimensi memeriksa diameter luar, membosankan, ketebalan, dimensi hub, lingkaran baut, jumlah lubang baut dan diameter lubang menurut ASME, EN, DIN, Standar JIS atau GB. Sealing face finish, raised face height and RTJ groove dimensions are also inspected to ensure fit-up accuracy and reliable gasket sealing during installation.
4. Pengujian PMI dan Pengujian Hidrostatis
PMI testing is used to confirm material grade and alloy identity for duplex and super duplex flanges before shipment. Pengujian hidrostatik dapat diatur sebagai bagian dari perakitan pipa atau persyaratan proyek khusus. SASA FLANGE menyediakan EN 10204 3.1 sertifikat, traceable heat numbers and inspection records to support end-user and third-party verification requirements.
