Every flange manufactured for Water Infrastructure 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: Remax Forge produces standard ASME B16.5 and B16.47 flanges up to 60 inches, which fully meet or exceed AWWA Class D/E pressure ratings. Custom AWWA flange dimensions are manufactured upon request.
