Flange Quality Assurance

As an ISO compliant manufacturing company, we perform both in-process and final inspections to ensure flange quality. In addition to traditional dimensional measurement equipment, we use high-end laser devices to verify tolerances. We offer non-destructive testing (NDT) on flanges for the most stringent applications to confirm they are defect-free. We provide material traceability and inspection reports to document that our products meet the highest standards of excellence.

We leverage numerous fabrication methods, including plate burning, CNC and conventional machining, automated flange drilling, robotic welding with automatic positioning, and many other state-of-the-art technologies to produce flanges with precise tolerances and fine surface finishes. Our expertise spans all flange types, including blind and reducing flanges, spectacle and paddle blinds, O-rings and Victaulic rings, adapter rings, and many other custom flanges. We can provide thermal stress relief, die-stamp/etching identification markings, and apply protective coatings, all in-house.
