Detil Produk
Hastelloy lap joint flanges are backing flanges designed to be used with a compatible stub end, allowing easy alignment and dismantling in piping systems handling highly corrosive media. Compared with integral flanges, the lap joint design reduces replacement cost in alloy piping because the flange does not contact the process fluid directly when matched with the correct stub end material. These flanges are widely used in chemical plants, platform lepas pantai, flue gas treatment, acid service and high-purity process lines.
SASA FLANGE supplies Hastelloy lap joint flanges in standard and customized dimensions according to ASME, EN, DIN, JIS, GB and project drawings. Each batch can be delivered with chemical analysis, pengujian mekanis, pemeriksaan dimensi, pengujian PMI, EN 10204 3.1 certificate and full heat number traceability to support critical industrial procurement requirements.

Inspeksi Produk
1. Pemeriksaan Komposisi Kimia
Chemical composition inspection is carried out to confirm that the supplied Hastelloy flange material matches the specified alloy grade such as C22 or C276. Test results are checked against the applicable ASTM or ASME standard limits for key elements including nickel, kromium, molibdenum, iron and tungsten to ensure corrosion resistance and material conformity.
2. Pengujian Sifat Mekanik
Mechanical testing is performed in accordance with the applicable material specification to verify tensile strength, kekuatan hasil, elongation and hardness of the nickel alloy material. These tests confirm that the flange blank or forged material has the required structural properties for pressure service, fabrication reliability and stable performance under demanding operating conditions.
3. Inspeksi Dimensi
Pemeriksaan dimensi mencakup diameter luar, ketebalan, membosankan, lingkaran baut, diameter lubang baut, number of holes and overall tolerance according to ASME, EN, DIN, Standar JIS atau GB. Untuk flensa sambungan pangkuan, special attention is given to fit-up with the mating stub end, smooth rotation during alignment and correct flange face geometry for site installation.
4. Pengujian PMI dan Pengujian Hidrostatis
PMI testing is available to verify alloy identity on each flange or batch using portable spectrometer or XRF equipment, helping avoid grade mix-up in critical service. Hydrostatic testing is generally applied to assembled piping or special flange components when specified. SASA FLANGE persediaan EN 10204 3.1 sertifikat, inspection records and full traceability documentation with shipment.
