Large diameter flanges can be manufactured out of any steel material grade. They come in flange faces that include:

RTJ (Ring Type Joint)
RF (Raised Face)
FF (Flat Face)

Some of the most common applications for the large diameter flanges are for subsea / onshore pipelines and ASME pressure vessels.

Custom made large diameter flanges can come as large as the customer requires and made to their design specs. Our extensive heavy-duty manufacturing capability combined with a large inventory of plate stock allows us to meet the most complex and challenging quality and delivery requirements. 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.

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.
