What We Do
Supplying precision pipe flanges for critical industrial applications nationwide.
Flanges.IO is a full-service pipe flange supplier serving the petrochemical, oilfield, and waterworks industries. We maintain a comprehensive inventory of ANSI, API, and AWWA flanges in over 50 material grades, enabling us to fulfill orders quickly from stock without the lead times associated with mill-direct procurement.
Our product range covers all standard flange types including weld neck, slip on, blind, threaded, socket weld, lap joint, orifice, and specialty configurations. We stock sizes from 1/2" through 60" in pressure classes from 150 to 2500 per ANSI B16.5 and B16.47, as well as API 6A flanges for wellhead applications and AWWA C207 flanges for waterworks service.
Beyond standard catalog products, Flanges.IO provides custom flange manufacturing for non-standard sizes, materials, and configurations. Our manufacturing partners maintain ASME certifications and comprehensive quality management systems. Every flange ships with full material traceability documentation.
