Key Advantages of Our SS 304 Flanges
Exceptional Forging Quality
Forged under strict thermal regimes to guarantee uniform grain flow, zero micro-porosity, and reliable structural integrity.
Perfect Sealing Faces
Flange sealing surfaces are machined with precise concentric or spiral serrations to assure a secure, positive seal under pressure.
Mill Certification & Traceability
Supplied with certified test reports demonstrating chemical makeup, hardness readings, and ASME dimensional compliance.
Interactive SS 304 Flange Weight Calculator
Select your flange specification below. This calculator uses standard ASME B16.5 dimensional references combined with a density of 7.93 g/cm³ (specifically adjusted for Stainless Steel 304/304L alloys) to give an approximate theoretical weight.
Figures are theoretical estimates based on standard ASME B16.5 approximations for reference only; final certified weights are confirmed at the time of order against the applicable dimensional standard.
Typical Industrial Applications
- Chemical Processing: Refineries, pharmaceutical flow lines, and transport pipelines dealing with organic chemicals.
- Food & Beverage Processing: Hygienic processing pipelines where cleanability, product safety, and zero oxidation are mandatory.
- Water Treatment & Desalination: High-volume municipality networks, water storage hubs, and light saline reverse osmosis setups.
- Power Generation Plants: Steam line connections, non-critical process loops, cooling water networks, and auxiliary pipelines.
