Description de produit
Stainless Steel Weld Neck Flange ANSI B16.5 Class 300 316L Forged ISO Certified PMI Tested RTJ Face 1 to 8 Inch

Stainless Steel Weld Neck Flange – ISO Certified & Fully Tested
WNRLN manufactures high-integrity stainless steel weld neck flanges backed by rigorous quality certification and comprehensive material testing. Designed for critical high-pressure applications, our 316L weld neck flanges deliver exceptional reliability with full documentation and multi-level inspection protocols.

Quality Certifications
  • ISO 9001:2015 Certified: Our manufacturing facility operates under a fully certified quality management system with annual third-party audits
  • PED 2014/68/EU Compliant: Products meet European Pressure Equipment Directive requirements for CE marking
  • EN 10204 3.1 MTC: Full material test certificates documenting chemical composition and mechanical properties for each heat
Testing & Inspection Protocol
  • PMI (Positive Material Identification): 100% PMI testing using X-ray fluorescence (XRF) analyzer to verify alloy composition and prevent material mix-up
  • Hydrostatic Pressure Testing: Each flange tested at 1.5x rated working pressure to verify structural integrity and leak-tightness
  • Ultrasonic Testing (UT): Volumetric examination to detect internal discontinuities in forged material per ASTM A388
  • Dimensional Inspection: Full dimensional verification against ANSI B16.5 tolerance tables using calibrated CMM equipment
  • Intergranular Corrosion Test: ASTM A262 Practice E testing available upon request for sensitization resistance verification
Technical Specifications
Standard ANSI/ASME B16.5
Pressure Class Class 300 (PN50)
Material ASTM A182 F316L
Size Range 1" to 8" (DN25 to DN200)
