Flanges & fittings for chemical processing: 316L, Hastelloy C-276, Inconel 625 for aggressive media. Full MTC traceability. Quote in 30 minutes.
High-alloy forged flanges engineered to withstand aggressive organic and inorganic acids, alkalis, and toxic chemical process media across fertilizer, polymer, and fine chemical plants.
| Material Grade | Specific Application & Fluid Service |
|---|---|
| Hastelloy C-276 (UNS N10276) | Hot contaminated mineral acids & wet chlorine |
| Inconel 625 (UNS N06625) | High-temperature organic acid processing |
| Super Duplex 2507 | Phosphoric and nitric acid streams |
Every flange manufactured for Chemical Processing Industry Flanges is forged from 100% prime tested steel billets with complete melt-heat traceability. Remax Forge performs Spectro chemical analysis, tensile testing, yield strength verification, elongation measurement, and Brinell or Vickers hardness checks according to ASTM A105, A182, A350, and ASME Section II standards.
For critical fluid handling and high-pressure duties, we execute Positive Material Identification (PMI) testing using calibrated XRF analyzers, Charpy V-notch impact testing at design minimum temperatures (down to -46°C for A350 LF2 or cryogenic conditions for austenitic alloys), and grain size examination compliant with ASTM E112.
Non-destructive examination (NDE) procedures including 100% Ultrasonic Testing (UT) for internal defect detection, Liquid Penetrant Inspection (LPI), and Magnetic Particle Inspection (MPI) are conducted per ASME Section V specifications.
Every dispatch is accompanied by an EN 10204 Type 3.1 Mill Test Certificate (MTC) detailing complete chemical, mechanical, and heat-treatment batch records. Independent third-party inspection (TPI) by global authorities including Lloyd's Register, Bureau Veritas, DNV-GL, TÜV, and SGS is routinely facilitated upon project requisition.
A: 316L covers general chemical service. Step up to Duplex 2205 when chlorides or higher pressures are present. Select nickel alloys like Hastelloy C-276 for severe hot mineral acids, wet chlorine, or where stainless steel fails.
