ASME B16.5 Stainless Steel 304 Plate Flange DN100 Class 150 with Full Certification

The ASME B16.5 Stainless Steel 304 Plate Flange DN100 Class 150 is a cost-effective flat face flange solution for general industrial piping systems. Manufactured from UNS S30400 austenitic stainless steel with full quality certification documentation, it delivers reliable performance for non-critical and moderate service applications.

• EN 10204 3.1 Material Test Certificate: Complete certification with chemical composition analysis, mechanical properties (tensile strength, yield strength, elongation), and heat treatment records included with every shipment
• 100% PMI (Positive Material Identification): Every plate flange undergoes positive material identification using X-ray fluorescence spectrometry to verify grade conformity and prevent material mix-up
• ISO 9001:2015 Certified Manufacturing: Produced in an ISO 9001 certified facility with rigorous quality management covering incoming raw material inspection, in-process quality checks, and final dimensional verification
• Hydrostatic Testing: Each flange is hydrostatically tested at 1.5x design pressure per ASME B16.5 requirements to verify structural integrity
• Dimensional Inspection: 100% dimensional verification including flange thickness, bolt circle diameter, bolt hole size, and facing finish against ASME B16.5 tolerances

Flat face plate flanges provide full-face gasket contact for even load distribution on mating flanges, typically cast iron or non-metallic. They are the most economical flange type and are widely used in low to moderate pressure applications where cost efficiency and reliable sealing are prioritized.

Water treatment plants, HVAC chilled water systems, fire protection piping, general industrial process piping, irrigation systems, and utility services. Suitable for applications operating at ambient to moderate temperatures with non-cyclic loading conditions.
